Gear help

So I had a set of 3.73s installed, did the speedo correction and everything else, but ever since the install the shifting at normal driving and downshifting from a slow roll hasn't been right at all. It goes through second gear really fast at normal driving, and almost feels like the tranny is slipping when you put light pressure on the gas pedal at a slow roll. Could this be a tune/gears issue or is it a tranny issue?? Any help would be appreciated.

When you say you did the speedo correction, do you mean you reflashed the PCM with the new gear ratio?

Possibly a converter issue or maybe you need to adjust you shift points.

This isn't going to fix your speedo from being off. Your still going to running high mph wise and be off

How should I go about adjusting this? All I have is a handheld tuner *hypercrap*, and I don't really have access to any tuning program.
