I have a 99 5.3 and i would like to know what kind transmission rebuild kit i would need to get. I plan on really modifying my engine, so i need to have a tranny that can take it. Does anyone make part kits to strengthen my tranny, or who makes complete trannys for this purpose?

 

FLP, give them a hollar. the have a nice setup for our trucks.
