.. As I've said several time I worked at a dodge & Jeep stealership from 2002 to about 2009.. I was a service adviser when these trans would not shift it was most of the time . The governor pressure solenoid and the transducer.
... Sad to say I didn't want to just change these items. So I was stupid and took mine to a shop that I thought I could just get to swap trans for me. Well he didn't check mine and ended up just pulling the trans out and taking it to a trans shop he'd made a trade with . The trans guy pulled my trans apart & found nothing wrong . So he replace the paper gaskets and the seal kits and put it back together. Then it was reinstalled and it would still not ship so they checked the solenoids and low & behold that was what it needed . So I got another 250.00 of parts an it now shifts good . But it did come home with a leak on the pan.
......... I hate taking something to a shop . And I sure knew better. .. Napa now has one of those parts .
