my truck wont go until i hit lockup and then she will go go go! but until it acts like it is slipping is that the tc? fulid is good and fresh it has been like this for over 30k which i put on it in less than 3 months pulling hard.....even transported a boat almost 2000 miles that weighed 18k no problems once it hit lockup any help? also i will not downshift? and all my toys are unpluged......

 

It says pot in place of tps in your sig, what is that?

 

Potentiometer(spelling) I think. More reliable.

 

yeah lil red ie right.....but i have it unhooked right now trying to find out whats wrong i took it to a shop and they said it needed to be rebuilt that is pure BS i have put over 30k on it in less than 3 months like it is and it has not got any worse now those are towing miles i transport boats from fl to ca on a regular basis...

 

Since it won't down shift sounds like the valve body is acting up, and not giving enough press to the tc to get you going.

 

WHy don't you give me a call and we can talk about exactly what its doing and see what we can do from there. A few things come to mind but the description just isn't as precise as I would like.
