oka i think i found the problem i got the tranny out of a 99 and i put it in the 2000. i read some were that something needs to be swaped i belive it is the silonid pack is that correct

 

Does the transmission shift into 3rd gear at all. 45 to 55 mph?

 

every now and then i try not to push it untill i get the problem fixed

 

everything was identical except the gov. pres. sil. sensor those connectors are diffent other then that its all the same.

 

The sensor was changed to the plastic sensor,however with the 8 pin connector disconnected, it still would manually shift....

I'm just asking, did the old transmission shift at all into 3rd gear? Or not at all?

 

the old tranny had no forward gears at all when i pulled the pan there was metal chuncks in the bottom of the pan it was toast. the tranny that i put in the truck was working just fine and worked great till the motor went. it has less then 20000 miles

 

Another thing to try is to disconnect the transmission throttle cable.....Now be careful here, because the transmission IS GOING to slip with throttle above light acceleration( would be a good idea to place rear axle on jack stands)....If trans will shift to third , then you know you have a throttle linkage concern....( also be careful moving the gear selector while rear wheels are off ground)

I have a 4.7 v8 dodge durango slt and i have reverse first and second but no 3rd or above. Ive replaced the input and output speed sensors ive replaced the governor pressure sensor and the the whole solinoid pack on the valve body still nothing. Any other ideas?? Im at my breaking point on what to do next

 

You are posting in over a 3.4 year old thread. But it's time you take it in and have it monitored with pressure and electrical.
