I finally finished up installing the 700R4 in my 67 GTO. Everything is buttoned up and appears to be running great most of the time.
The problem I have is that once it is warmed up, been driven for about twenty minutes or so and I am cruising around at town speeds. The transmission shifts through all four gears quickly and the engine bogs down. I will be at 25 MPH in fourth gear. Now this doesn't happen for the first 20 minutes or so. During that time it shifts like you would expect.
