The tall first turns off people with 3.xx gears.

Well the trans does great!!! But now i am back to my orginal issue when the built trans blew. I have a drive line vibration under heavy load... I measured my pinion angle and it is pretty far off. The driveshaft was at 0* and the rearend was pointing up 6-7*... I raised the tranny some to get it to -2* (pointing down to the rearend) and i added some 4* shims to the rear end.. The vibration is better but not gone... I am gonna order some different shims and go from there.

I used part of the HD2 kit, basically just the springs. I reused the stock separator plate, i just drilled the fed holes slightly bigger. I did not use the boost valve or the relief spring thingy... I used sonnax parts instead...

Do you think the stall speed is too low or too high? Honestly i would not want to go any bigger because i daily drive it... My wife is allready gonna bitch about it cause it stays in the upper RPMs now and it is louder..
