my durango began shifting erratically yesterday, it was fine on the way to work then did not want to shift from 1st to second without letting off the gas then it would try to down shift right away, i was able to limp it home and after finding this board i changed the output speed sensor on the trans to day. The transmission does shift firm and does not feel like it is slipping but the problem, although improved after the new sensor, stills seems to be there. Witch sensor would you guys suggest changing now> TPS or the rear speed sensor on the axle, or do i suck it up and just do both ?
thanks in advance

 

problem has changed now after a real test drive it will shift out of first gear if i let off the gas completely but still hangs in first if i dont. Then when i went to park the truck it now will not shift into park. I would really appreciate some insight thanks

 

this morning it shifts into park but will not start from park only nuetral, replaced the 3 easy sensors no change, goes to the mechanic tomorrow i guess, anyone have any idea what it might be?

 

did you break the Throttle Valve Cable, or is it hung up?

 

cablw is intact cannot even get into park manually at the trans

 

i could really only see the rod to the top of the tranny the tvc is that in side the tranny?

 

tranny pan came down today for those interested, its seems i had actually lost second gear, the head on the tension bolt for the belt the shifts into second actually fell out and into the pan, anyone seen this before? after dropping the valve body and reinserting the head im going to call it for lack of a technical term, and adjusting the bolt and the belt all looks normal, just got the valve body back in, should be back on the road tomorrow and we will see if its fixed

 

reinstalled part, put valve body back in ajusted belt and all seems well, actually shifts better than it did before hope this thread sheds some light if someone else runs into this issue.

 

Thank you for the update, I am glad to see you are back on the road!

 

Back up for now, now we will see if the repair holds. The belt looked good i just dont think its been adjusted turning any of the tranny services ive had done.
