When i broke my 3 GST trannies, it was never the Diff that broke. It was always the output shaft and the top of the 1st/2nd gear shaft. Has anyone ever had to take apart a 'built' tranny to see what was actually done in it? As far as i know, there is no company that makes aftermarket hard gears for these trannies. I know TRE does a process of shot-peening to harden stuff. I'm just wondering what they're actually doint to them to make them stronger. When i built mine, i always did it by the book with the endplays and preloads on the bearings. What usually killed my tranny was wheel hop though. It didn't break right at the time of wheel hop but wasn't long after. I had all the motor mount mods, etc.. and still couldn't prevent it. I don't think any tranny is built to withstand wheelhop.
