Does anyone think this could be the cause of rough shifting in a 2008 with the 4 speed? I had a buddys dad who works at the local dealership look at it, no fluid problems or leaks. He is talking about reprogramming it. Anyone have similar problems?

It throws no codes or lights or anything.

 

I have the 08 3.7 Big Horn with the SAME EXACT PROBLEM! but haven't looked much into it, mine shifts hard (not hard hard but you can notice it) from 1-2, every time if i accelerate hard, and when its cold out it shifts rough from 2-3 (rarely) not all the time...other than that, i haven't contacted the dealer about or looked into what the problem with it is.

 

Xdak is there a chance you can take a vid to compare a lil

 

There really isn't a way to show it in a video, you have to be in the truck to feel it.

 

Same here, I hope to get mine flashed/reprogrammed soon. I'll let ya know.

 

Alright sounds good! thanks a lot

 

I guess it's better to have a hard shift than a soft shift. If it's a soft shift the clutch packs wear out quicker.

 

Mine will hold 3rd gear from 35 to 55. Won't shift no matter what I do...

 

how is it possible to have a 4 speed these days, you have no overdrive?

 

i hear ya
