uhhhhh HELLLLL.
OK matt I went to drive the jeep today just pokin round town and
here is what I feel...
When from park to drive it goes normal 1-15 was ok then it bucked

when I let off gas it let the transmission rev up... if that makes sense, not the MOTOR as the RPM's did not increase at all

i THEN noticed if I gently apply pressure on the gas pedal you can hear the tranny and motor line up together and then engage and I can go until I let off the gas again then same thing...

NOW when I put in reverse... it automatically goes into that mode sounds like grinding though... I have no reverseit sounds like the gear reduction is to low for the engine to engage the tranny or something....

drop the pan...check for debris...

[XJ4IV]

pan dropped... totally free of ANY debris!! yeah the oil was nasty but whatever... so Matt told me to shoot the solenoids with brake parts cleaner and "exercise" them... did that and reinstalled em, checked over the filter and decided that needs to be replaced... more tomorrow

How much detail do you want :)

[prcjeep]

uhhh. well i guess enough to determine if I could manage a rebuild on my own or at your shop...

TCM shot so I ran the solenoids through on off toggle switches witch worked well except that I gotta flip the switch to switch the gears I wonder if I can run this kind of set up through a home made paddle shifter one side Be cylinoid 1 on and off the other side be solenoid 2 on and off I know I have to keep cylinoid 3 on a toggle for the TC what does everyone think? Any Opinions will be very appreciated.

I have wondered how an AW4 works. Still do.

Your TCM sends power to your first solenoid for Park reverse neutral and 1st it sends power to your first and second solenoid for 2 and only your second solenoid for 3rd and none for 4th your third solenoid turns on and off your torque converter .
