I put a rebuilt tranny in my 84 hot air car and it doesn't shift as expected.
The 1-2 shift is perfect. Right feel, right rpm shift point, but the 2-3 and 3-4 shift are very soft and happen almost immediately. So in a typical slow acceleration (with wife in the car), it might be in first gear for say 4 to 5 seconds, but its only in second for 2 seconds before it upshifts to 3rd, then another 1 or 2 seconds later its in 4th. These shifts are much sooner than I would expect. It goes into OD lockup as expected around 45mph.
If I manually upshift it, it will hold the gear as expected until I upshift to the next one.
Is this a problem with the governor, or is it TV adjustment, or maybe something else entirely? I've followed the procedure and believe I have the TV adjusted properly and the trans rebuilder provided a new governor, but it really didn't change anything.
