    Mine fried with about 315

    Lets say you go all out... get a built level 3 4l60e. Might hold that much.. but if you have 800 hp you have the money to do a built 4l80e conversion.

    and that is where the fun is at.

    Anyone that is running that much HP(over 400 IMO) is running on borrowed time.

    the t-56 is made to handle much more than 400hp boys and the rear is only a problem when u beat on it........simply going fast isnt beating on it

    Pretty sure it isnt MADE to handle but it can handle. I have seen in person 10 second 10 bolt cars. Same thing.

    Get a good rebuild with quality parts and dont ever worry again.

    First off, to pull in those upper gears requires horsepower. HP=More stress on the driveline. I was commenting on how the 10 bolts can hold a lot of HP and not break while some break on stock power.

    Upper gears in a STOCK tranny arent meant to handle that much HP.

    5th gear alone tops out at 181 MPH but I dont think any stock tranny has scene that.

    6th at 268 mph.

    kinda obvious.

    Last time I checked the original poster has an 02 trans am. Totally different setup, I dont see any torque tube under my trans am. As well as no 10 bolt with a 3.42 gear setup on a c5...

    Do some research on the internals of a t-56 that was used on the F-BODIES.

    Stock 1999 T56.
    Still in one piece....although I do figure it is on borrowed time.

    And I don't do high speeds. 5th and 6th gear are not meant for WOT runs.
