i have a 99 durango 5.2l i just bought and im having issues with the tranny ive checked the other forums and downloaded troubleshoots from here and my first question is the battery size detrimental to transmission shifting issues?

 

Battery SIZE shouldn't matter, battery condition can cause some interesting problems though.... Of course, low voltage in the system will wreak all sorts of havoc, as the PCM depends on good voltage to get accurate readings from the various sensors.

What is your trans doing? (not doing...)

 

It hesitates into reverse and it continues to shift uncontrollably unless it's ( i assume) getting the correct amount of throttle. This is the first dodge I've owned do it's hard to put a finger on where to start

 

Shift uncontrollably? What do you mean? Is it shifting early? Late? Too often? Not at all??

 

It can't pick a gear

 

Probably just an electronics problem....... Change the fluid/filter, adjust the bands, and replace the governor pressure sensor/solenoid.
