Hmm so popped the trans pan off the dipstick is a pita but got it out as a whole one piece. Will separate it later.
Tested the solenoids and solenoid b the one im the back by itself is dead.
Idk if the chart you gave me is off or not but when i tested it at the tcu pin 12 gave me no reading which ended up being solenoid b not a when i dropped the pan. Just letting you know fyi from my testing.
Either way the solenoid is bad.

Here's a new AW4 Solenoids ID pic. Thanks for the heads up.

So how many qts should the tranny take i read about 4qts since i dropped the pan and changed the filter too. Thats what i put in 4qts
I drove it around for like 10min and checked the level on idle in neutral and its at the "ok" mark should i add a lil more? Its not even at the 2nd hole or do i maybe have to drive it for longer n then check it
Other than that the problem is fixed and was not really hard to do. Only the dipstick was a lil tricky since mine was seized up so i had to heat it up and rotate the pan around to pull out the dipstick with the pan.
Putting it in was actually much easier than i thought it would be. Put the pan on, fed the dipstick through the top lined it up used a piece of wood and mallet hit it and it popped into place and bend the bracket back n bolt it up.

Bad tcm
So I did all the checks on your TCM test proceedure and I got the correct readings according to the specs provided, a couple a bit more or less but really close. That means my TCM module is bad right, that would fit my “one morning jeep just wouldnt shift by itself” symptom right?
Yes, you can test the TCM inputs, including the solenoids resistance, from the TCM connector.
It's a PITA but worth the effort in order to eliminate any bad input.
You'll need a digital Volt/Ohmmeter and a safety pin.
Refer to the connector pinouts and procedures images below.
Gain access to the TCM by removing the plastic trim panel and the steel knee blocker from under the steering column. The TCM is located just to the right of the steering column.
Remove the connector from the TCM.
Read the pinouts and procedures before beginning
For the resistance readings remove the battery NEG post connector (reattach for voltage checks).
The red entries on the pinouts are my notes.
Use the safety pin inserted in pin cavity 24 on the TCM connector for attaching the meter - probe. Makes it easier to probe the other pin cavities with the + probe.

Unfortunately, this thread is over 6 years old and I'm pretty sure CCKen is no longer with us. Sure miss him.
