AW4 Issue

[Kittrell]

Alright, so I am having a problem with this tranny. It's having shifting issues. Doesn't want to shift out of first or second without alot of work. The problem is more prominent trying to get into 3rd then second. I have to rev it up to about 4-5k and then let off the gas and most times that will do it. Though sometimes I find myself bouncing off the rev limiter. So I figured I would start simple and replace the TPS. Next thing to look at would be the TCU I imagine. Any input on the situation would be appreciated.

Did you check the fluid?

Did you check the fluid?

Yeah, I did all of the basic stuff.

adjust the T.V. Cable?

Disconnect TCU or TCU fuse and you can shift manually.

1-2 = 1
3 = 3
D = 4

You can eliminate tranny as problem and focus on electrical/adjustment issues. You can also drive w/o redlining - just no second.

Did you adjust TPS to specs.?
