Matt, I certainly appreciate the referral! We do offer the bolt-on bracket kits for the 99-07c GM Trucks. However, I just want to clarify that our kit is not the one that was featured in the original video, as we have had some confusion among a few customers about that. I do not believe that seller from the PerformanceTrucks.Net Forum is still around, but he was not affiliated with us and our kit does differ from his a bit. Unlike his kit, our kit centers the cooler in the grill opening rather than offsetting and our brackets are powder coated silver, rather than left raw aluminum. Our kit includes all mounting hardware (stainless steel), but DOES NOT include any solution for adapting the OEM cooler lines. A universal plumbing kit is included with the 40K cooler, but we do not supply the quick connect style fittings or a compression fitting to adapt the line. I typically do not advise the use of compression fittings on transmission cooler lines due to the risk of collateral damage in the event of a failure. However, if someone is set on using one, I highly recommend the use of a steel Swage-Lok style compression fitting over a brass compression as the bite force is substantially higher. We do offer braided stainless PTFE trans line packages that are designed to replace the entire OEM line assembly an run directly from the transmission to the front mounted 40K cooler. These may be overkill for a lot of applications, but I at least wanted to mention that solution for guys looking for a 100% direct-fit bolt-on package. Our bracket sets are not bolt-on for the 2007-2013 model trucks as those trucks use a welded lower brace unlike one that is bolted in place like the 99-07c trucks. Our kit can be used on the 07-13 models, but would require cutting the OEM lower brace/bracket off and using self-tapping hardware to mount our lower bracket which is designed to occupy that space. Additionally, some clearancing of the foam bumper support padding may be required in order to clear the line set on those models.

I just got mine from Glenn's along with the 6AN hose / radiator bypass kit.

Tip: tie a piece of string or fishing line to old line before pulling out. Once old line is out, tie the string to the new cooler line and use the string to pull the new line back into place.

I did this and it's a great upgrade! I recommend pulling the bumper (just 4 bolts) to make it easier to flip around the transmission lines.

Man what a lifesaver... just blew up my 6l80e last week and while im replacing it i wanted to do the cooler so i bought this exact one! And now you're going to show me how to do it. Also didnt know about the retrofit to keep stock lines!

Wow, I should have done this on my wife's '09 before towing a TA enclosed trailer across the country last June. I thought the stock cooler would have been enough, but it ran hot quite a bit in the mountains and in the heat of the day in the Great Plains. Keep the videos coming!

I spit my coffee out when I watched that 😂

I've watched this before, but I am now doing this, and rewatching it has helped me tremendously. Thank you for the link, I just ordered it and I will let you know how it goes.

That Lucas additive has been great. I put it in...through the dipstick tube, and it did take FOREVER. But the clunk in park to reverse and a slight slip in 2nd disappeared in the 4L60 in the same Tahoe of my other comment. No slips or problems since I did a fluid and filter change and added it in. I thought the tow would eat it up and have to add more, but it was great and still no problems. I wish I added it during the fluid change but I thought the change might have solved the problem initially. I also taught my wife to use the parking brake and let the truck stop before shifting into park or reverse and it hasn't come back. Well over 180k miles on it and still going strong.

This is a great upgrade. Also had my TCU and PCM tuned for firmer shifts. Great package together. I also use Lucas on a very low, mileage transmissions. It’s a great preventative maintenance.

I very much enjoy and appreciate the accuracy in which you portray the joys of mechanical projects. The things we will do as men to save money and pride.

Instead of installing both transmission lines you can cut the hard line on both ends of the leaky rubber part. Flare the ends of the metal lines and use rubber line to hook them back together. (Be sure the rubber line is marked TOC and isn't fuel line. TOC= Transmission Oil Cooler)

I added the largest Derale stacked plate cooler with fan onto my 2003 Savana Van. Mounted it under the chassis and bypassed the radiator. I was in the South so no severe cold winters. Delivered bottled water so was waaaay over payload to start the delivery day. I had the 4L60E rebuilt, when I was ready, at 400,000 miles. Trans temp was always 40*-50* less than the coolant temp. The only downside was that I had to replace the cooler twice because of leaks. Out of warranty of course. So, the lesson to learn is to get a trans cooler no matter what. HEAT is what kills transmissions.

I've had awesome luck with all my 4L60E transmissions. I built one up for my latest build. The problem isn't so much the design, it's GM cutting corners so the trans doesn't last as long. Metal checkballs pass through the separator plate on the valve body. Then you burn up clutches. One some older 4L60E's the sun shell also tends to brake (I think they fixed that on later ones). Lastly, not catastrphic but the plastic accumulators tend to crack. These all can be fixed for a few bucks... If you have a later model 4L60E with improved sun shell, then simply lowering your service pan on trans and replacing checkballs with plastic, and accumulator with pinless metal will get you pretty well there. Otherwise, 4L60E trans is pretty awesome. You can also throw a boost valve in the pump while you have the pan down. Most of newer ones come with a corvette style servo too. They are actually rock solid after you do a few simple fixes like that. If you crack the case open you can go with a wider band, and some slightly improved clutches. It's a solid design.

Friend you are Awesome. You are not afraid to change anything on your rig. Very helpful

You're colourful language makes this video so relatable LOL

I put one of those Tru Coolers on my 04 Jeep GC a couple years back with a trans temp gauge. Even crawling through the rocks in AZ the trans never got over 180, cruising down the freeway sees it at around 160.

Cardboard is the best thing to put under the truck - you can slide in/out of it way easier and super easy to fold up throw away when done.

Glad you didn't edit out the part where it leaked. That's real life. Not like watching some BS show on TV where every bolt comes out without effort and everything fits the first time. Thanks for the video.

I used the brackets when I did the Tru-cool on my truck but made up -6an lines and bypassed the radiator and put a temp gauge inline. The cooler makes a huge difference for sure to help the 60e live.

I don't know if you have done it yet, but changing out the power steering cooler is also a great change. The top loop of the OEM coolers, at least up here in the north east, have a tendency to rust out and cause a leak.

Listen to me when I tell you I don’t know a damn thing about cars. But I love this series. You inspired me to just clean up and upgrade my car myself. I’ll definitely be installing that back up camera and touch screen radio. ❤️

That "dead plug" is actually the ambient tempature sensor.

I know this an older video but a helpful tip for anyone using a compression fitting, put a dab of never sneeze or pipe dope on the compression sleeve before you put it together. It lets you get it a little more snug

Great idea with mixing before filling

So cool. Great video and editing!

I just installed a derale 13403. It’s way easier than the tru cool to install. You can mount it right where the stock one is and use the existing lines and factory fitting. No crappy barb fittings or soft hose. It’s rated for 37k btu’s so just a little less than the tru cool. With it being a stacked plate it’s built stronger and is a smaller footprint letting your radiation get cooler. You just need an adapter to go from the big inlets in the derale to the smaller factory fitting. I then used 4 flat corner brackets from Home Depot and some self tapping screws to attach to the existing frame. So easy!

They make compression fittings for brake line. I have used them on a few of my vehicles. Not the ones for brakes but general compression fittings.

really torn between this 40k or a smaller unit with a fan for cooling the trans in my 12 tahoe. It's high mileage and the temps are way too high for my liking, even when not towing. Changing the fluid helps initially but they do creep...and once that fluid hits a 220*, it gets there pretty quick from then on out until you change it again. I can appreciate both the work you document and the frustration you show...real life DIY struggles.

Watching you struggle with that bag made me lol. I remember changing thise lines for my 86 z28 and it came in a bag just like that. So the bag featuring cursing was about the same. 😂

I cant believe I actually installed one of these 40k trans coolers to my 09 Cobalt 2.2 😂, they were known for having overheating issues I'm heavy traffic so I bought one of these and installed it inline with the radiator cooler. Before the install transmission temps would spike over 230°F but after the install it never once got hotter than 180°F. Now I'm debating if I should install one on my 07 Sport Trac just to help it chill out lol

The best technical difficult reference!!!

I wish I knew about this channel before I changed my lines. Lol I had plenty of technical difficulty moments. All the work is for purpose and you bring us along. Subbed.

New not always good! That leak sucks after all the fight with those lines. Glad it worked out.

I kid you not I installed one of these on a 09 Chevy Cobalt 2.2, the transmission temps never went higher than 180°F even under heavy stop and go traffic lol. Gonna get another one and install it on my 07 Sport trac inline with the factory aux cooler.

That sensor that looked like a dead end plug is a temp sensor for your mirror

Love it keep making tahoe videos

for the bad oil lines, you can just cut out the rubber hose pieces and then with a Dremel, keeping the metal oil line intact, Just cut off the metal clamp and use two "constant tension springs" in place of the proprietary metal clamps. What happens is over time, the rubber hose shrinks and the propriety clamps stay the same size and it leaks, constant tension spring clamps fix the issue. Buy new hoses to replace the bad ones at your local auto store, taking a piece of the old rubber hose for reference. So four total for one rubber hose, I have been running my Silverado with that fix for over 4 years now without it slipping off.

Excellent video. One question for you. After installing the trans cooler did you notice your engine temp being higher? I know the stock engine temp gauge sucks and is not that accurate, but any difference you could tell or see? I have a 03' Z71 Tahoe and I am looking at buying the cooler and the install kit as you have done. I pull a 7x16 enclosed cargo from time to time and I will be pulling a boat to Lk. George there in the Adirondacks in August. By the way I live in NC. Electric fans are in the near future so that should help with the radiator surface area being blocked by the trans cooler.

That lucas stuff, best if you warm it up next to a heater vent to thin it out and flow better. For future reference

Cool I really enjoy your videos!! Nice work!!

You should add a remote trans filter, beats the hell out of dropping the pan.

Matt thanks for the video. Be aware that the affiliated link you have for the cooler is for the model number LPD47391 which DOESN'T have the cold weather bypass which is required for vehicles being driven in temperatures below 32F. You may want to check which model you installed or fix the link. I just found out the hard way by following the link. They sell people the LPD47391 from the link and describe it as having the bypass. LPD4739 has the bypass. I learned this once it showed up and I read the box. I see were you live so you might take a look at yours just in case I plan on pulling 7500 travel trailer so I need it to be right. Right now there is a $50 dollar difference between the two.

You should think about changing out the power steering cooler as well. Mine looked like yours just before it sprang a pinhole leak and pissed fluid everywhere, luckily I wasn't far from home. If you have the hydroboost brakes as well it's all on the same circuit. If you lose power steering, no brakes either.

Id say use the old trans cooler as powersteering cooler??that should work no?

Tech tip. If you get ciips out. Give them a squeeze. Or better yet replace them. 01 lumina did flush. Refilled and on test drive popped a line. Clip gave out. Dont reuse if budget allows or if clip goes to land of lost socks and 10 mm. Just buy a handful from GM

Have you done the trans temp gauge upgrade on the stock cluster? I will attempt it on mine this week and see it if works. I heard/read somewhere that 2004-2006 are wired from factory with trans temp but they just don’t have the gauge. So all you would have to do is add a stepper motor, new gauge overlay and a needle and it should work. Fingers crossed.🤞

Nice video. Is that not too much cooling during the winter outdoor temperatures? Do you partially block it off in the winter when not towing like they do on big highway transport trucks?

This video was exactly what I was looking for.......ie, the links you posted were money!

Could you provide the part numbers for the transmission cooler lines? I want to add the cooler but use the factory cooler lines.

Do you run the same amount of oil with the cooler? Or can you increase the amount if you add a cooler?

What are you guys doing for the hookup of the lines of my truck didn't come from the factory with the external cooler only the internal radiator cooler? Buying extra tubing and using the barbs with the hose clamps or getting the GM fittings? If getting the GM fittings like Matt did what lines then?

I highly recommend since you plan on towing to get a corvette servo it goes into the side of the trans (don’t even have to drop trans or anything and is less then 50$). It’s firms up the shift. Depending on budget I would also recommend getting a custom tune done by a reputable tuner. Explain it’s a daily and you do plan on towing and he can help with the trans lasting as long as possible.

Brad Miller if the 4l60 takes a dump you can build it up with the sonnex updated drive shell and the 5 gear planetary set, did that to my brothers chevy express, 5 years later, lots of city driving and it still shifts smooth and strong.

So I'm hoping you will answer this question, I've seen other videos where they have bypassed the radiator with the true cool cooler and they are getting much lower temps, My question is does your tahoe have a transmission temp gauge in cluster,and if so what temperatures are you achieving now?. Considering doing this to my 04 Silverado and bypassing the radiator for the cooler temps otherwise the transmission temp Will still be the same as before with a stock cooler, with this true cooler installed due to the thermostat controls the temp of antifreeze running thru radiator. I have found a kit online that replaces stock lines And stock cooler with high compression braided lines as well as the true cool but we're talking $450, As opposed to roughly a little over $200 on the kit you did. I did just have my 4L60 rebuilt back in October And I want to extend the life as long as possible.. Thank you in advance for answering my question

@LsxMatt did you choose to replace your trans lines? Mines are good, so I’ll use rubber hoses to do the trucool installation.

Do you know the size of the fitting used to be able to keep the factory lines ???

With the trans cooler are you adding more oil or same amount as stock?

Do You have to change the lines when adding a transcooler or could you just replace the transcooler or add a transcooler if your truck don't have one

Doesn't it block your engine radiator and require extra transmission fluid? How do you get a accurate reading on the transmission dipstick now?

Have a question about your efan install what are the differences in a 01 mine works but only with a toggle switch and only one pin 42 is able to be hooked up

Hey Matt nice video just did my install yesterday....but now the trans won’t even get over 100 with driving any advice?

Can you please help chucke2009 with his hero 7 Hey is stuck using 480p quality

Have you noticed the engine temp raise at all, since the trans cooler blocks the airflow to the radiator? I live in So. Cal. (hot weather)

I'm doing this now because my radiator cracked and I just found out my trans fluid going into my coolant radiator. I don't quite understand it yet. My trans fluid goes into my radiator then into its own cooler than back to the tranny??? Why not just use the whole radiator for coolant and a larger seperate trans cooler. I see the radiators come both ways with and without trans fluid going to them. Anyone know what's what? Or best route to go if changing both radiator AND trans cooler.

Does the radiator get hotter since the larger cooler blocks it from the air flow.....?

On GMT-800 trucks (2001 Silverado 1500), do you have to purge air out of the Tru-Cool Max Transmission Cooler?

You can put Lucas transmission bottle in boiling water to heat it up so it comes out a lot easier

I have a 05 avalanche and hate the fact that it doesn't come with a trany cooler except for the one in the radiator. I live in south Texas. Does anyone know of a kit to add one

What did you use to cut the line? Can you please post a link if you can? Maybe Amazon?

How has the trans held up over the years. Using my truck to tow as well just want to get an idea of what to expect

LsxMatt hey man I have a question on the cooler position. Doesn’t it need to me mounted with the inlet and outlet facing upwards? Saw another video where someone was speaking about that cooler isn’t a “self bleeding” cooler made to be mounted with the outlets facing down.

I installed this on my 2001 tahoe... Trans fluid is now WAY too cool. I need to put that thermostat bypass in, did you eventually install the bypass? I'm thinking to splice it into the rubber section behind the core support.

With a bigger cooler isn't it alright to have a little more fluid seeing more will be in the actual cooler itself ?

How do you order the brackets from performance truck??

My 2003 towing 7,160# briefly reached 210°F on I-84 east of Pendleton with air temp at 78°F,,,, with factory cooler

do i need the thermal bypass if i live in Omaha, Nebraska?

How is the Tahoe holding up with the tru cool since the install ?

Where did you get the new transmission lines can you send me the link? PLZ

4l60E 2700 High stall Torque converter, Performance clutches and gears... Everyday driving no tow with heavy acceleration every now and then. hwy and city more hwy. SUV mid size is this cooler needed???

Nicely done kid!

What fluid did you use in the 4l60e?

@lsxmatt would you ever do a electric fans conversion and Instead of having it running a clutch fan on the Tahoe?? For better cooling on towing. If you do I would like to see a video from you of it, so keep doing videos I like them and they do help. Thx

Mine works great , but still would love to have the 4L 80 trans just to pull up hills better.. hard to find though.

Would painting the tru cool cooler black effect its cooling ability?

If you use the specified transmission fluid for your transmission you should not have any slipping or any other problems with the transmission for at least 220,000 miles(from New). As soon as you start adding other fluids to your transmission you will find it will wear out faster and have problems sooner(like slipping, etc).

Is the cooler bracket still available?

You may as well start looking for a 4l80..no regrets and it handles power much better and you can tow in O/D..atomic fab has a better price in the 40k bracket..
