Well i finally got my car ripping at 10psi with the afc and bigger injectors and 2 hours after i got it out of the shop the tranny went. there wasnt any problems with the clutch or tranny when it went in but when it came out it as winding and poppin out of third gear then it just went i cant even put it into gear now. should the tranny hold up for 10psi? im so pissed i cant belive this

Sounds like you broke the 3rd-to-4th shift fork. That sucks man!

sounds like they had fun with your car when you werent there

should our tranny be albe to take 10psi without beating it because i know i barely ever even get on my car. i know they beat that thing.

Sometimes trannys just go. Anything that is a machine or a part can break at any time. And HRC runs 25 psi on their RS with a bigger turbo so the answer is yes.

what did they do to your car in the shop? see if you have clutch fluid, they might have forgotten to bleed it if they did empty it.
