What type of Trans do I have?
06-07 monte carlo is FWD no RWD so they do not use the same transmission as the f body's
i believe the monte carlo is based on the grandprix, and i blew up 3 of those tranny's in my GTP
To answer your original question, its hit or miss with 4L60E's. I'm pretty sure it wasn't designed with 300+ hp in mind originally, and most people end up having to have it rebuilt even when their car is stock. Some have them last a long time, others (like me) go through several in just a few years. If you plan on serious mods, I would look at getting a built transmission, lots of good sponsors on here that can get you a bulletproof one made.
BTW, lol this is post 999.
