torque converter going out

Asked by Nov 11, 2013 at 10:00 PM about the 1999 Pontiac Grand Prix 4 Dr GT Sedan

Question type: General

well as far as I know, because I am an engine and body guy not a tranny guy, I got two codes for my transmission. the first one being a torque converter slip, the second one being in the neighborhood of a long shift problem? From what I've found this usually means the torque converter is going bad. when I first start up the car It idles and runs fine I can drive it for a few hours or so but after the transmission have time to heat up to even operating temperatures It begins to shift really hard and I have rev variations while driving. My intent with this car is to beef it out to get better gas millage like a wrapped high flow exhaust, better intake, and a better ignition system. I was wondering if there were any 6 speed transmissions out there that I could put in to get better mpgs or If I have to stick with the standard 4?
