Sorry, its been a long day, and I can’t organize my thoughts, so its going to be very messy, but I wanted to put in my knowledge from dealing with these Chrysler transmissions.

I wouldn’t say these transmissions are bad. They have a lot of mistreatment with the fluid used in them. Chrysler also published that dexron could be used in the transmission if ATF+3/+4 wasn’t available, which is absolutely not true, in a way, setting up a bad reputation for these transmissions.
Their main issue, besides the diff pin, is the control solenoid. The control solenoid has none serviceable filters which clog when you don’t change the fluid regularly.

Also, these transmissions only have clutches, no bands.

The speed sensor used on the transmission also controls the speedometer for the car.

The only way to diagnose these transmissions is to use a code reader to figure out what the transmission computer knows. Usually you first want to know what codes are stored in the transmission computer, and also the Clutch Volume Index (CVI) before you proceed with anything.

Also, its an overall fairly simple transmission, mechanically, with a ton of electronics to make up for the missing mechanical stuff. Rebuilding it might be cheaper than trying to replace.
