Just because it won't shift at WOT does not mean that after you let off a touch, it shifts, that you can't go back to WOT. Same with my 87 GN.
Never could on my car. I even added the B&M "upshift valve" and if I got to happy with the loud pedal, it would back into 3rd and run off of the tach. I eventually destroyed that gearbox (after 10 rebuilds) and got a new core, it turned out to be a 350 box and it would make the 3/4 shift while wide open. Then, I converted the car to a manual. My teal car is a factory 5.7 liter car, but it's now a 6 speed.
Yea, the cars that wouldn't shift were limited by third gear, the 5.7's would shift and they ran 150+ mph on top.
