Ok guys, I have been reading all the AW4 threads and how to adjust it and how to check the solenoids. However, I dont think any of these are my issues so before I go and screw something else up I figured I would tell you what I have done......
Jeep is a 2000 XJ with 4.0 and Aw4 4x4 (2wd hi,4x4 hi,N,4x4 low) Np231 I assume.
Donor motor 4.0 pulled out of my wrecked 2001 (100,338 miles). Cleaned it and painted the block. Left the flywheel and torque converter on it (part numbers were the same from 01 and 00).
Disconnected everything and Removed the 4.0 in the 2000 XJ I bought (217K miles) that the owner told me needed a motor due to the head being cracked, washed the engine bay and installed the 2001 motor into the 2000. Used the TB off the 2000 motor as the 2001 TB idled real low so it was easier to swap TB's instead of all the sensors.
Jeep idles great, runs good, but when I test drove the jeep it seems that on normal cruising it stays in gear and runs up higher than normal into the RPMs but if I slightly let off the gas pedal it will shift up. Manually shifting the selector seemed not to make any changes.
Thanks to kastein on here I unplugged the gray harness near the dip stick, drove it in manual mode shifting up and down, and it drives and shifts as it should unplugged.
So now my question is the jeep drove/shifted fine before the motor swap so I assume I have a bad connection or bad ground as it seems to be a electrical issue. I have searched for a diagram but did not find one. So what connections grounds should I check or is there something I might be over looking?
Transmission wiring connections I know I unplugged:
1. Gray Plug at the oil dip stick and the black ones.
2. Grounds on the side of the motor above the oil dipstick
3. Two plugs on the transmission (one is crank sensor - other not sure)
4. Grounds on motor between alt and motor mount
And I did remove the transmission shifter cable but it went right back in the right position and selector shows all the right positions.
Im assuming I have a bad plug connection, a bad ground, or I'm over looking a plug undone somewhere. I'm not a automatic person so all of this is new to me.
Any help or idea's I can check would be appreciated.
Thanks
