AW4 has to be driven like a manual tranny?

So, I know this is the YJ section however a lot of us have put the AW4 into our YJ's so I'm throwing this question in here as the XJ section is frequented much less often.

So for arguments sake, let's say this is an 1995 XJ aw4 that is in a YJ... with a 4.0...

Problem:

Jeep wont move when placed into "Drive". When manually moving through the gears the jeep moves when placed on "low" via the tranny shifter. Then moving up through the gears with the tranny shifter we can get to hiway speeds. "drive" works once the jeep is running on the road. When comming to a stop, jeep must be placed back into "lo" then 2nd, etc....

Any thoughts on this? Again, "drive" doesnt move until you get the jeep moving by manually shifting through the gears using the tranny shifter.

Doesn't that indicate a failed TCM?

Did you swap over any wiring, or splice any? I put a 96 AW4 / 4.0 setup in my 89. Used the complete harness from the donor XJ, including the transmission connections. There's a great writeup on wiring in an AW4 if you don't have the harness that includes it.

just throwing this out there, sounds like the TCU has failed.
