Search. A few in depth threads on this. A lot faster than waiting for a proper response.

The Google, she knows much. Id just mod the auto or sell it and buy a stick personally. If you are an 04 especially you should leave it alone. Those transmissions are good for over 700hp in stock form.

I have a 99 and loved the automatic until with 4.10 gears until I supercharged the car I think its too much power for the trans cause its not working near like it did before the charger.. under boost it will not shift into second gear unless I let off the throttle almost completely.. but normal driving it works great

What sort of aftermarket cooler did you put on the trans? Did you do the J-mod or a shift kit? Did you do a full fluid change to include flushing the converter? The automatics in the 99-03 cars can take more power than the motors can. The 04 has what basically amounts to a built trans right from the factory in the 4R75W.

The car in this video is running a totally stock low mileage 3650. Was waiting for the input shaft to blow up and swap to a 26 spline but apparently it never gave up the ghost. You be the judge lol.

Your auto died because you put a ton more power through it and didn't do anything to help keep it cool or better lubricated. With a J-mod and a good dual fan B&M cooler that trans would likely still be alive and kicking.

The 3650 is fine. Just because you know someone who had a bad experience doesn't mean they are all garbage.

Also if your goal is to go fast in a straight line, keep it auto and swap in a fresh trans and an aftermarket stall converter. You'll run better 1/4 times with that setup than you will with a stick all other things being equal.

My trans didn't die yet but I'm afraid if I keep running it she will die.. I like going to the track but I enjoy playing with the manual better.. I only been driving the car boosted for almost a week and in normal driving its fine heck even 3/4 throttle it fine but full boost forget it
