How much power can a stock L36 transmission handle?
Well, it'* like the title says, how much power from the engine can a stock L36 transmission take without biting the dust?

100 ft-lb of torque.
just kidding.
depends. some here have died stock, others have held up to more abuse...
<edit> i don't think i've seen 95naSTA have a tranny swap yet, and he'* prolly our fastest L36 around, so hopefully he'll chime in if he has any dyno info to share...

I know buck531 (L36 lumina) over at clubgp put down 233hp/251 tq with a stock tranny and intense GEN1 LSD with higher 90k+ mileage. It didn't last much longer than that dyno though.
And TimberWarp (gpgt) has been running a csc kit on his stock tranny/diff for a while now.
Those setups are both geared to higher end power unlike the m90 with it'* monster low end torque. So they are a little more friendly.
I've read over and over that the differential on the 4t65-e is the major weak link. Also, the internals are said to be very similiar between the -e and -hd. Swap the 4t65-e diff for the 4t65-hd one and you should be able to handle much more power.

4T60-E swap to HD Possible 4T65 HD
I have a 96 bonnie se with a 99 l67 swap and it finally started taking out the stock tranny .
I can still drive it for about 300 miles or so with no trouble then sometime i have issues just driving in the city for about 30 miles . It starts with over drive going out then eventually 4 and 3 . then after the call cools for about 30 mins its gtg . Not to sure what the issue is but the tranny fluid did get burn alittle :( and it leaks some out of the driver side . But i want to do the swap before it finally goes . I want to atleast do the 4T60-e hd swap and MAYBE the 4t65 hd depending everything that is involved with it .
Also is it bad idea to run with the supercharger by pass closed at all time . Sadly it has improved my gas mileage and the low to mid throttle torque is awesome but not to sure if it will aid in premature failure of anything
