I own a 96 Chevy Impala SS. I just bought it. It came with a professionally installed Supercharger from Procharger. When I floor it from 1st to 2nd gear (only happens from first to second), the car has a hard time switching gears. Let's say the car switches gears at 6000 rpms, it goes up to 6 and drops back down and goes up to 6 and drops back down and finally switches gears. I don't know whats wrong, and I was wondering if someone can help me. Sorry for my lack of knowledge on the topic. I hope this is enough information.

 

how much of a drop in rpm's

 

I'm assuming it's an A4?

How much boost?

If your RPM is dropping before the car shifts, it probably isn't a tranny problem, it could be in the motor. You might be having some belt slippage? I don't really know, I don't own an LS1 so I've never had any experiences with belt slippage

 

Is it a stock converter or aftermarket? Check your shiftpoints and your rev limiter. In some instances the stock computer has a hard time reacting fast enough when new mods(NO2, SC, H/C) have been installed and so the car hesitates to shift when it should.

 

Yea, just let the computer relearn.
