AW4 Shift sequence
I have a question, I am not sure of the final shift sequence of my AW4 trans. Does the torque convertor lock up after the shift into 3rd and remain locked when going into 4th overdrive, or, does the trans shift straight thru to 4th and then the torque convertor lockup??? Does anyone really know the trans sequence?

Yes, 4th then lock-up on an 89. 87 was 1,2,3, lock, 4 no lock, lock.

Never knew the 87 shifted different...
I was wondering if a 88-90 TCU would work in 91-96 too, I miss the 25mph downshift when I drive newer jeeps.

Theyre the same box, with the same markings, and same plug... Im just wondering if theyre internally different and somehow wouldnt work.
The main thing I can think of is the renix tps reads "backwards" compared to a HO.

The TPS has two sides. The engine side works differently but are you sure the trans side does?
