slip in a 400 THM
Hello, All
Just a quick question I have a THM 400 if it is "manual" shifted
it works great no slip ( also has a B@M shift improver kit) ...i know NOW that it is bad ......DOH any way back to the problem if the car is left in "D" and allowed to shift for herself it will accell normal in 1st when it shifts to 2nd at 40 MPH or so it will quit accelling and the engine wil start to rev with the car not gaining any more speed ????? what the heck is going on?? if i put her to WOT it will act normaly any ideas ?????
