After a few passes the other night, I'm thinking I need to tweak my 47RH shift points.
My 1-2 shift happens at ~3500rpm, 2-3 is about 3200rpm. I'd like to get the 1-2 closer to 3000-3200rpm without changing the 2-3 shift point. I'm guessing that's going to require a spring change inside the VB? Is it more than that? My line pressure @ WOT is 190psi or so.
I have a lock-up switch for OD, but it won't lock at WOT, so I just let it shift on it's own. But, it hits at about 2900rpm, I'd like to get that up around 3200rpm also. My TPS was 3.6volts at WOT, I've raised it to 4.0 volts. Is that going to help, or, is there something else in there that's going to govern the max shift point for OD.
I'm usually trial and error from week to week, but the track is closed for the next few weeks, so I'd like ot get an idea what to expect before then.
