Anyone know what an automatic shifts at (RPM wise at WOT) for a 94 TA? The reason I ask, at WOT, it shifts a little past redline. Doesn't seem like a stock setting to me, but then again, what do I know?
I noticed today my shift point from 1st to 2nd was 6000 rpms. Now I accidently pulled the adjustment pin when the throttle cable broke so I'm not sure about how it is set. I was going to post a question here as how to set it but I hadn't got around to it yet.
2002 Electron Blue Vette, 1SC, FE3/Z51, G92 3.15 gears, 308.9 RWHP 321.7 RWTQ (before any mods), SLP headers, Z06 exhaust, MSD Ignition Wires, AC Delco Iridium Spark Plugs, 160 t-stat, lots of ECM tuning
Not sure if this will help anyone, I lowered my shift points for the 1-2 shift, and the 2-3 shift. My car really responded to that, most likely due to the 3.73s as well. I found that the elevated shift points were winding out the motor past the optimum recovery point.... That's the point in the rpm range immediatly after the shift when the motor is forced back into a lower rpm. Ideally, on a gearshift you want the motor to be in it's torque peak or just a hair below when it settles into the next gear. I haven't had enough time to dial in the 3-4 shift. I spent most of my time dialing in the first 1/8 mile and haven't found out if the car traps better winding out 3rd or shifting into 4th before the traps. Gotta love the LT-1 torque.
Also, you can't really depend on the factory tach being very accurate. It may say 6000, but it is likely 5800. There is a certain percentage of error, lag time, etc. that is hard to nail down with the factory tach.
