UPDATE: Got my GM Remanufactured installed. I got an upgraded billet torque converter from Florida Torque Converters. I did all the work myself and it wasn't too bad. I got my Tahoe up on stands/ramps and used a nice transmission jack from Harbor Freight. It wasn't really that complicated or hard except for some of the stupid GM electrical connectors. I also flushed the cooling lines and replaced four O2 sensors since the exhaust was off. I had to flatbed it to the dealer for programming but so far, it's driving great. Temps, with an updated bypass are around 160 degrees in the 90+ weather we are having now. Total cost was $4400 + tax for trans, $600 + tax for TC, fluid, and a few specialized tools.
Thank you to
