Is there any way to adjust the shift points on a 47re trans? I've thought it would be nice for towing if it would shift sooner and tonight just for kicks i did a couple 0-60 runs and it badly needs to shift sooner for that. It took 10 seconds to hit 60:doh:

You can adjust the TV cable to adjust shift points but adjusting it so it shifts sooner especially if towing can be a really bad thing.

Ok, so why is that hard on it? I have a rebuilt tranny and different valve body if that makes any difference.

You can adjust the TPS/APPS cable at the top (google it/or theres a thread or 2 here that have the link ) - or you can bend the plate back on tranny to give an extra 1/2" inch on the kickdown lever - saw a builder do this. If you shift to early -> you lug the motor down in a low rpm range -> which puts more stress on everything including tranny ..... I think generally want to shift around 1700-1800rpm under light throttle. For racing ?? Dunno ....... would still think you want to get the efficient shift points (1700rpm) so your not lugging , but you may need more fuel and bigger turbo to push your acceleration into lockup quicker ... as long as your rebuild can handle it.

unless you have a BD pressure lock on it you are putting the power to it before you have given it enough throttle to move the governor lever on the tranny far enough to start increasing the internal pressures and thus potential of slipping cluthces.
