So about 2 weeks ago i was taking some girls for a ride (in my truck..) and i went to launch her. Left around 35PSI and it left but in about 10ft i heard a loud pop and everything went into neutral. About 2 seconds later the truck is back in drive and I'm driving it home. So i lock it up and then i end up snapping the output. Now i got it back and went to race this guy last night. i left around 30 PSI with a fresh output (not billet yet $$$) and it did the same thing. I'm still driving it today though so i cant help but think the pop and the output arent related? Anyone else ever heard of this??? Never had this problem till the twins


Mods. 7x.013, 62 over 75, edge, meth, built Trans w/ billet input.

 

So update. I talked to my trans guy and he said its possible for the shift fork in the TC to disengage under hard launches??

 

so update... snapped output on 2nd gear lockup yesterday..... stock shaft survived one 1/4 mile run.... going billet now. maybe this was my problem.
