TCM 02 Durango
#12
You'd think.. Some are great. Most are bull**** just looking for money backed by jokers.
Thankfully I take my vehicles (all three, ford, gmc, dodge) to future ford fleet. They'll do anything at reasonable costs. Sadly the local dodge dealer I only use for warranty work (2012 ram). They wanted to charge me (01 durango) $1,600 for rack and pinion replacement and redo whole brake system. At the time I lived in Texas and I got that prior quote in Cali where I live now while on vacation. Anywho drove back home to TX an dodge dealer did work for $750. Now that I live here in Cali like I said, I just use that joke of a dealer for warranty work..
It's a shame.

I found a TCM from an 04 Jeep for $36 or something like that. I figured it would be cheaper than getting it re-programmed anyway so I just bought it and changed mine out. Its been working great since. I can't remember which year they had the rough shift issues and some other software issue that they had an update for but I think I read that the 04 year was clear of any issues or problems like that already so thats why I went with it. I do notice a difference in MPG and engine RPMs at highway cruising speeds for sure.

4.7...idk the Trans. But I did some more research on another forum, and found that IF the PCM/ECM has 4 connectors instead of 3, then the vehicle SHOULD already have been equipped with 5 speed. Then I Google searched the year, make & model. In all the YouTube videos I've found online the description states that earlier models & UPTO 2002 (all those vehicles had a MAGNUM cover I saw in EVERY video) suppossedly HAVE a TCM/TCU. BUT the specs I found for the 02 DD SLT 4X4 V8 4.7L (NOT a Magnum) came factory 5 Speed Transmission in the Google spec search?!?! At least in mine does??? My ECM/PCM was changed little over a year ago, due to ex wife using it while I was away on business and came back to multiple error codes. Error codes were as follows.... ABS, E. BRAKE engaged when it wasn't, and speedometer wasn't working. So I ordered a new ECM skinned/coded, changed out every sensor, & multiple other fixes.....and it still didn't fix the problems. Finally broke down and Had to take it to the dealer. $1900 later it was operational again. Still don't know what the dealer did to fix the problems. But.... I noticed that my MPG was ****tier than befsaid issues. Was getting around 16mpg, now I'm at 10.6mpg. Hence when I saw these fuel alternatives videos, I figured it would help me out. But... that's why I saw that my truck doesn't have a TCM/TCU, and why I started digging in to finding out what/why my truck is an "ANOMALY".

So, how many plugs on your PCM?
You can also try running a build sheet for your truck here. (all caps please, it doesn't like lower-case letters)

My ECM/PCM has 4 plugs. And as I found out that 4 plugs equals 5 speed, and 3 plugs equals 4 speed. So I guess I will just need to drive it more often to let the ECM/PCM relearn the fuel consumption usage. It's NOT a daily driver being a V8. But I may need to change that for a few months to verify if that is in fact the problem.
this information was included in the post you quoted earlier in this thread. . . . . . not sure why you had to return to google to figure that out.
although 2002 was a transition year, the 4-5 speed change was made mid-year so it COULD have either setup depending on when in 02 it was made, im not sure when the cutoff was.
