u can get the 02xx 400r turbo for free which is a way better trans they are good to 800 hp stock have most of the parts to build a 2000 hp trans out of them like the heavy duty 8 bolt pump which cost about 800 to 1000 to put in a trans

Bom dia muito bom o vídeo o conteúdo muito técnico e simples, abraço 🇧🇷

I am a retired mechanic you can take pieces of 90 degree angle and you can weld them together that looks like a big Square Lays potato chip when you cut these pieces of mangle together you can lay your valves in the group's this way you can take the valves directly out the exact way they came out about body because you do not want to accidentally turn the valve 180° the opposite way this will help you put everything in order so will you take valves out of the valve body you can put them in the exact order that you took them out of the valve body and place them on the tool then you can clean all the valves one by one I put them back into the valve up want you make sure everything goes and exactly the way it came out of the valve body easy homemade tool that I've made I have several of them they work really good you do not want to accidentally put a valve in backwards this could cost shifting problems the valves and springs will stay in place just how they came out of a vehicle and you do not have to worry about the valves and springs rolling around on the metal table hope this ideal help people that are working on Transmissions it is also very important to clean all parts thoroughly it only takes one particle to stick a valve in a valve body I've always use mineral spirits hot water and blow-dry with the compressor that's always work for me we have to be very clean when you are rebuilding a transmission Parts need to be clean and dry

New subscriber!!!!!

Great build. I really like the Smart Tech input drum, the Sonnax reaction tube and Smart shell. One thing I found that would make your build a little better is a torrington bearing that replaces the one remaining thrust washer behind the pump. I can't remember who did the bearing kit but I would think the bearing is available by size. This helps support the gear train a little better when we take the endplay down to .005.

Hmm very interesting I'll definitely look into that

Hi man, I love it how advanced you are. Few suggestions from me is Drill the Band release hole to .101. Also there is a rule of thumb, your 2-3 and 3-2 feed holes always have to be the same size. Also bang the torlon checkball before installing to the plate to ensure 100% seal. A lot of the times when you put torlon checkball in the separator plate, you can see light coming thru. Now for 4th acum in the case, leave the guts out and bang a steel checkball in the feed hole. More lube to rear planets = profit. You cant make 4-th too firm. Also, always block both 3-2 valves inboard and save the yellow spring to use inside the AFL spring if you dont have the transgo one. You cure a huge leak with this overcomplicated stuff on downshifts. Also use the Superior K0136 directional valve instead of 3rd check capsule. It's so ultimate. If you're low on vacuum on AFL, you can use oversized Central Valve bodies valve. Use fitzall valve to the TCC Isolator. There is a few things i learned from you. Thanks for your vids mate! Best regards.

I agree with the band release. I don't do the accumulator block in 4th for personal reasons, lol but it is a way to do it. Thanks for watching and the advice I love hearing other builder methods. Keep up the good work btw sounds like you love the 4l60e as well.

All good mods, but could you tap and Loctite a set screw in the feed hole for 4th accum, so if someone else ever does a rebuild they have the option to unplug it. used an old steel check ball to indent the separator plate for the torlon ball to sit in, dont hit the torlon checkball. I.m no pro builder but have learnt a lot off the internet thanks to the help form all you guys.

Thanks for all the tip and part recommendations. To return the favor consider drilling a hole in your take to put the input shaft through when loading the input drum. Anything that make it a little easier right?

Unless its a corvette i just cant justify all that over a 4l80e i mean i rebuild my 4l60e and put like $400 maybe $500 into it but thats me doing all the work

if u know what ur doing u can get the 02xx 400r turbo which is good to 800 hp stock but people run up to 1200 hp on them and u can get them for free i got 4 setups last year with the 450 hp 454 from 6,000 to 58,,00 miles on them all working perfect

Hi David I have a question for you Any reason why didn’t you use the pin less accumulator pistons I know you like those ones Please advise It will help me out for my high performance transmission built Nice work like always David Awesome videos too Bless

Do more 4l60e builds..

Is there any particular reason you aren't soaking your frictions before installing them? Won't they run dry for the first bit of start up? I know it takes a little time for them to completely impregnate with fluid and I figured it was the right practice to soak them until they stop bubbling before installing.

I really enjoy watching your videos. I just finished a 6L80 in a 2014 Silverado, My scan tool does not have the option for the quick relearn, Will the TCU relearn on its own eventually, or do I need to take it to the dealership?

Did the tcc valve you installed make it non PWM. Also what does those abuse plugs do?

@expressautotransmissiondav4207

2 жыл бұрын

Sorry I just seen this comment. The valve is not for pwm delete but with the valve and other vb changes it can be made on off. The abuse plugs act as blocks in the valve train. When they are over abused they begin to leak and cause cross leaks.

Awesome video ,is using the Sonnax pinless accumulators better than stacking two pistons in 3rd I’ve heard of this mod how does it affect shift feel?

@expressautotransmissiondav4207

2 жыл бұрын

The problem I have with the stacking is it still can have a leak around the center of the pin. Typically once it's stacked it shouldn't move hardly at all so it shouldn't in theory wear the pin hole. Either way the pinless accumulator doesn't change shift feel but does aid with preventing cross leaks for each side of the accumulator.

Awesome video! Thank you for all the build details. A lot of guys on here tell you what they do, but not how or why. This is along the same lines of what I want to do with my 09 Silverado. I've had 3 different local guys rebuild my transmission once each in the last 3 years.. all of them blew up a couple of months after their 1yr warranty expired. 🤬 I figured, I'm pretty mechanically minded, and I do most of my own other car repairs. Why not try to do this myself and do it right. LOL. But I do have a few questions if anyone would care to answer, I would appreciate it. With this higher HP setup, woud it be nessecary to put in a higher stall converter? Would I need to upgrade my rear differential for the highter HP? Are there any modifications that need to be done to the truck's computer for it to accept the changes. Or is it just plug-n-play? I'm just looking to make it a bit more heavier duty than just a factory build. Thanks in advance for any help.

You could tap the 4th instead of pounding in a checkball in case you ever want to go back--use a 5/16th - UNF (fine) or a 1/16 NPT (tapered pipe.) Then leave the piston & spring out and you'll get increased oiling to the rear. Which TransGo kit are you using, the SK 4l60 or the HD2? The SK the 1-2 piston goes in facing out. I usually go with the SK 4l60 kit and add the 7CS spring kit and save about $30.

I am certainly no expert on transmissions, but I recently watched a video on SummitRacing’s KZread page about the importance of the angle relationship between the engine and transmission. They showed how to measure it and adjust it. It just seems weird that you have had 3 failures in 3 years. Sure seems like it’s happening a lot to not be caused by something else than poor build.
