did you bolt the torque converter to the engine before bolting the motor to the tranny? or did you slide the TC foreward after the engine and tranny were together?

i bolted the torque converter to the engine first then the motor to the tranny

you don't need another tranny what you need to do is get the trans cleaned out by a professional to check for damage and buy a new torque converter.

I did the same thing with my 429 and c6 combo only I had 2nd and no 3rd.

what you will have to do next time is put the TC on the Transmission, make sure the slots line up and push the TC as far as it will go almost against the back of the bell housing before getting the motor anywhere near the transmission.

also if you keep using it like that then soon enough you won't have any gears forwards or backwards. and I'm talking less than 50 miles

thanks for the help. a new tc is better than a new tranny
