Ok so I recently installed a reman engine and dr evil tranny, everything is good except the one two shift at wot it wont shift out of first?? I thought it was the tv cable at first but even with it set as loose as it can go its still the same thing, the tranny shifts through the gears no problem at part throttle. any ideas??

 

Rather then getting our opinion, why don't you just call Dr. Evil and ask him?

 

Call the builder.

If he is still using the stock style governor pressure solenoid, if it is sub par quality or used it can become flooded at full throttle and wont up shift.
