your SE is a 98, does it have the 4T60-E transmission? or whichver one is extremely light duty, and is rated to handle not much more than the stock engine makes? i know mine is the wussy tranny, you might want to invest in that if you are going to be putting that much power to the ground...or at least attempting to make it go to the ground.

I know the 4t60-e is light duty but out of curosity how much can it take horsepower wise and torque wise before something breaks

I e-mailed pontiac a couple years ago and they told me:

My '93 stock rebuilt 4t60-e blew up my 4th gear drum, welded my carrier, and burned up nearly every clutch plate in there with a 2.2 pulley, intake, and exhaust.

I replaced it with whats in my avatar

So can the tranny take 235 ft Lb or 354 ft lb??

So would that cam destroy my transmission?

Just wondering I still got to get my bonnie running but once she'* running I was thinking of adding a few modifacations here and there and wanted to know how far I could push it before something breaks

Well I emailed zzp about the cam

They said my transmission will be fine with a cam,exhaust and my intake.

After the cam I'll probably beef up my transmission. Where should I start?

What are you going to do? Don't throw a n/a cam in there if your going to go boosted later.

As far as the tranny goes, i think the diff is one of the weaker links. Engineered Performance has a clutch type LSD available. I haven't come across a review for that particular tranny though. The guy pontiac jeff there can put together gear ratio conversions for you too, but only if you buy the LSD with it. You have the option of 3.33, 3.43, or 3.73 final drive ratios. I've also head that the gear/chains are interchangeable between the 4T60s and 4t65s. So thier aftermarket solutions could work for you. I'm pretty sure they make Raybestos clutches for the 4t60 too. But if your close enough to zzp, you might want to have them do a rebuild for you. They have a 4T60 in thier 12 sec n/a gt.
