Torqueflite taking too long to shift into 2nd gear

RockinRobin said
727 torqueflite reverse manual valve body. Builder cranked up the pressure a little for me for firm shifts.
I have the shift light set to 6400rpm but my data log shows that the shift happens at 7200 rpm. It feels to me like it shifts right when I move the shifter, which I am banging on pretty hard (B&M Megashifter). Been like this ever since I switched to EFI that has datalogging (about 3 years ago). If it was slipping I think I would have material in the pan.
2nd to 3rd shift happens at same rpm as shift light. I want shift at 7000, so my workaround has been to lower the shift light to 6400 and basically guess at the 2nd to 3rd shift.
I do not want to spend money on a tach with multiple shift lights or spend $$$ on a different shifter. Is there a band adjustment or something else I can do?

Whose valve body and what line pressure are you running? Is the valve body low band apply? Also what is your front band adjustment at, along with second gear ratio lever? Is there any “flare up?” when you shift 1-2 or does it seem to happen firmly? Also, what gear ratio is the trans? Is it stock ratio or does it have a 2.74 low gear in it?

Do you leave with both hands on the steering wheel? Or one on the shifter ready to shift after you leave the starting line. Depending how fast the car wants to come out of 1st gear, could be where the increase in rpm is. So it could be a combination of things and there could be nothing wrong with your trans. In my own experience, I watch the tach and the shift light is there to remind me to shift if I am steering the car because it tried to go left or right off the launch.
