Guys with fast 6 spds, what do I need to keep from breaking them
What do I need to do to keep from snapping input or output shafts? I am thinking of having them cryo-treated. Has anyone else out there had this done? By the way, I am building a 383 motor with plans to spray it, I need to know what I have to do to keep from putting in an automatic. Thanks a bunch

The torque arm is relocated. No, I havent broken anything yet, except for that damn 3-4 shift fork...keeps getting stuck in 4th gear. I just know that sooner or later I'm going to have trouble with breaking output shafts. I've heard of a few done before, but I dont know the exact point power-wise that I am going to start breaking stuff.

~775rwhp (haven't dynoed it since going from 150 to 200hp nitrous) with still intact T56. I am getting it rebuilt with the Viper output (and ?input) shafts this winter to see if it's up to 900-950rwhp! If it breaks: G-force 5-speed.

Improper TA pinion angle is the biggest cause of broken input and output shafts.
One of my friends just ripped apart his input shaft. I think he set up the Sphoon TA with too much pinion.
Anyways, D&D is designing a kit to convert the f-body 27/28 spline input shafts to the viper/03 cobra 31/32 spline. Suppossed to come out sometime next year.
Either way, the t-56 we just tore apart is getting sent off the get all the internals cryo treated. I'll let you guys know how it turns out.

GreenbeanZ28-
Mine keeps getting stuck in 4th gear also. When it first happened, I thought it was the shift fork, so I replaced it with the steel unit. Then out of the blue, about 3,000 later, while I was just driving normally, it got stuck in 4th again. I wasn't even getting on it!!
I pulled the tranny out of the car about a month ago, but I haven't pulled it apart yet. I'm thinking I might have a bent shift rail or something. Anyone else have an idea as to what is wrong?? Thanks for everybody's help!!
