Automatic Transmission - Ok Here's the Deal!!!!!! "TCI 4L60E"

Ok just got the trans back 2-4 band broke!
But when i droped it off to the shop. For them to pull it out and put the new in. It ran perfect just no 2nd and 4th. But now with the new in my car is running SO RICH its fouling all my plugs out:bang: but if you goose it it clears up but when you stop it dies out.

Any advice would help thanks

OH yeah i'm running the jug and a tune plus i got real cold plugs (the car is built)

you may want to check and make sure that the O2 wires didnt get pinched between the bell and block

Ok thanks
