how much is too much?
Does anyone know how much added on power and torque a stock 1992 trans can take?
(without nitrous) so all the power is always active.

I've got the 4t60-e transmission and i know that it can handle up to 354 lb-ft torque. I emailed gm for those numbers. You have the 4t60-hd tranny so it'* gotta be more than that.

Of coarse this is with "extensive" modifications too mind you.

87-91 Bonnevilles had the 4T60, 92-96/97 had the 4T60-E & the 97+ had the 4T65-E.

RPM'* are your real issue with that transaxle.
400 is no problem with a well built unit but when it’* a high revving unit then you will find premature/excessive wear.

sorry for stealing the thread but...what is my tranny called in my 88le. it just says metric hydramatic div. of gmc on the pan. back to the topic...your stock tranny was made for being a grocery getter and not hot rodding so i'd say only 50 or so hp over stock but i dunno.
