Great site, glad I found it. Only my second post. I just got a 94 GT Convertible, off road H pipe, dynomax (?) muffs, 355 rear gear and Motorsports underdrive pulley's and K&N. My Q is, why do these little devils shift so quickly? I pull out into traffic and within a few seconds, I'm in overdrive already. Also, I know there were some problems with the automatics, my car has 49,000 miles on it, is it hard on the tranny to activate the overdrive bypass button in city driving? It sure sounds more beefy this way.
