Well, I cleaned my MAF and the kick down seems to be working properly so I'm thinking that probably eliminates the TPS but, the transmission still shifts strange. It does it around 3rd gear at around 2100 RPM otherwise it is not that noticeable. Here is a link so you can watch what happens: http://www.youtube.com/watch?v=Y-NofFHPDGU P.s. my cruise control stopped working this night too (yes I already checked the vacuum lines, it no longer makes the clicking noise like it used to when I activated it). Any help is appreciated, thanks in advance!

 

I watched your video and the shifting seems completely normal to me. Mine shifts the exact same way. I also get 15 mpg and am happy with that considering the vehicle is heavy and is in 4wd all the time. Hope that helps you.

 

How many miles on the tranny and when was it last serviced?

 

I did do a transmission flush about 600 miles ago along with a filter change. The owner before me did not use dexron III when he replaced it, thankfully I caught it quickly and was able to solve the odd grinding noise which was a result of improper fluid. Ive also considered doing another flush and drain the whole system to make sure all of that other fluid is COMPLETELY out. I have another question for you all, when I start the vehicle on a cold day it takes awhile for the transmission to start shifting at its normal RPMS (usually much higher than normal). I don't know why it is doing this but, it will resume normal shifting after about 3-5 minutes (probably just warming up, but I want to check if anyone else experiences this). I've also asked some other p38 owners if it was normal for it to look like it is shifting 8 times, and they all said yes. I guess its normal, however weird it might be lol.

 

You might want to send me your tele number and I'll call you.
