trying to hold my limped trans together for a few more months and fulfill my need for speed at the same time... C3's are toast so ive only been racing until 4th is topped out. no sign of wear or problems in gears 1-4 and converter feels perfect. curious about how much abuse stock clutches (besides C3) have been able to take. thanks

Well since the C1 and C2 clutches have 50% apply at best; they won't hold much.

If your going into the trans upgrade c1-c4, trust me I went with a kit that just upgraded the c3's along with some pump mods and I ended up smoking my c1s.

Ended up costing me much more in the long run.

Its not like there is 1 clutch pack used for every gear....and C3 is "5th gear"

the allison doesnt work that way. If one (or more) clutchpack is/are completely smoked you arent gonna go anywhere. If C3 is smoked, its not like the trans will work perfectly fine in everything except 5th gear........

I can build it for you as well, im not sure how far you are from me..
