Race trans, A&A brake( have yet to use it just foot brake it)
Made a pass at track, car just sat there like it was spinning/ slipping, went 1.90 60 foot, acts like it “ catches” then takes off.
Made another pass, same thing. Car always hooks, 1.45 ish 60 foot.
Drove it back to pits, all three forward gears seem to work just idling around.
Reverse doesn’t work, put car in park, want to creep forward

Any ideas? Trans has been in car several seasons, never done anything but change fluid

Sounds like a problem in the rear clutch, probably overpowered the Belleville spring and popped the piston out of its bore.

Could it be a sprag issue?

A failed sprag won't affect Reverse or make it creep forward in Park.
