turbo 400 slips in 2nd gear

hi
i just rebuilt my turbo 400 and it slips in 2nd gear. i aired checked everything was good . put it in drive it holds 1st gear until you back off the accelerate then it goes into 3rd gear . if you change it Manuel from 1st to 2nd then it slips in 2nd
and 3rd good the engine brake works fine in all gears any help thanks

Sounds like the sprag is in backwards

it has some drive in 2nd then if you accelerate it start to slip

SPRAG: It's in backwards

thanks ill pull it a part

It's an overriding sprag (it works like a ratchet. it locks up in one direction and ratchetts (slips) in the other.

If it's in backwards it will work under low load, but slip when you get on it.



Good luck:D
