when i drive down the highway and accelerate then decel, it constantly throws my truck into limp mode but does not show a code. i hook up my cheap code reader and hit erase it runs fine again. im told the cause is from the transfer case, but when i get codes there tranny codes p0746 p01174 p02563 p0700 p0763. what could be the cause?

 

Is trans fluid level correct? do you have a programmer on truck? Could be a problem with the pressure switch manifold, low fluid level, or trans slipping.

 

I know I have a transfer case seal leak not very big. And I had the ECM rest and it still did it. But I haven't noticed any slipping
