Man I'm loving these videos on the durango..

I removed that little air horn there from the box, but it breaks. Plus I like my fix to it better I hot glued it back on and now it has no air gaps

Love the videos Martin I’ve done many Jeep upgrades thanks to you. I have been looking in to swapping my 4.7 to a stroker 4.0 I wish you could do a series on them many people could use some good info.

Ty for that info . That is awsume to know . I got this dakota from my deceased father

About to do this to my 2001 Durango SLT Plus 4.7

Great job Martin! my 02/03 deserves better and even if it should pull harder from 1st to 2nd gear, I'm liking it! No, I'm loving the whole idea because my Grand Cherokee was a Sept 2002 and to be quite honest, it just doesn't seem to shift like a 5 speed and I know how bad that sounds but hell's bell's, I want a Grand Cherokee that breathes fire and moves out smartly just like it has a hemi or an interceptor motor even if it has a 4.7 H.O. under the hood! It currently has 177K plus and i was going to have a fluid and filter(s) change and I was going to a trans specialist that's been in the biz since 1970 and ask him if the fluid pressure could be bumped up a bit just so that i don't have that slush bucket shift a going on! That type of shift started in about 400 miles ago and the the trans doesn't act like it has been abused but the trans filter does seem like it might seem a bit restricted although the fluid color is within reasonably good condition. Thank-You for that hot tip and regard all you video's to be valuable, through and through!!

Did this 2 years ago and it's good for keeping the engine at a lower Rpm at higher highway speeds (80+ mph). Only thing I've found is it almost eliminated 4th gear, in 5th it would almost always prefer to downshift to 3rd then back up to 4th for a second and then to 5th again to stay. I know 4th and 5th ratio are very close to each other but I definitely feel Chrysler could have programmed the TCM to utilize 4th a little better. It's funny though that the government mileage ratings for 01-02 are the same as 03-04.

I just took the truck to Arizona and back, with some hilling driving. The truck would shift into 4th most of the time on the hills which brought the RPM up 600 from 2000 at 70 MPH and only downshifted once into 3rd and that brought the RPM to 3300 to 3500 at 70 MPH. I have no completes, I love it.

Hey Martin ! I just grab myself a tcm from the junkyard off a 2004 Cherokee for my 2002 ram 1500 I installed it and I didn’t have any major issues only thing is the car has really long gears now as the ram I have has a 3.51 rear end

On my 99 Durango 5.2L 44re trans the tcm is integrated into the pcm. The 4.7 L V8 I think was the only style motor that had the separate tcm from the pcm for the trans. Sucks to would love to have 5 speed without having to do a bunch of mods.

Yeah, they need to do something about this section of interstate.

The TCM stores the band adjustments and certain pressures from the old transmission. Can’t be cleared except with DRB3. Also, it’s technically unlocking 6th gear. On upshifts, the 545 (they’re all a 545RFE) is programmed to skip 3rd. So 1, 2, 4, 5 on the old programming. And then 1, 2, 4, 5, 6 on the new programming. 3rd is only used on a downshift from any of the gears higher than it. Also also, the trans may shift extremely hard from 1st to 2nd when doing this swap and will return to normal when the original TCM to that trans is reinstalled. It won’t relearn to soften the shift. Another also, removing torque management will cause zero harm no matter what no matter what. A firm(er) shift in an auto reduces heat, slip and wear and will increase life.

The transmission is a 545RFE. It sounds like there could be a problem with the blend doors on your HVAC that could be a concern if you can't get to the blend door motor.

If you do get a CAI can I recommend Injen brand?? I must pre state you will have to relocate your cruise control servo motor as I did. Well worth it, and you may choose to do the TCM too just for space. Stuff you seem to like to do. All the other CAI’s I could find do not come all the way to the front right of the engine bay, they stop short of an extra bend right in front of the ECM and sit over the exhaust manifold, a lot of them do have boxes. The Injen brand one does come all the way to the front corner but does not come with its own box and a deflector shield instead that l did not use. I opted to make a box that pulls from a hole in the fender that’s already there. I should make a video about it, I think it came out well for homemade box.

You'll hear complaints about oh now my transmission is hunting for a gear well it's probably shifting more than it did before but of course it is you've just gained another gear so it's trying to keep it in the optimum torque range. So if you went to a 8 or 9 speed transmission how many times do you think it's going to shift then. And for a mod that cost less than $50 more like under 40 I think it's worth finding out if you like it or not. So later when Durango and Dakota went to the 545 are those people complaining that they have a 5 speed transmission and that it's hunting for a gear and wish they had the 45 instead I doubt it.
