I’ve got a 76 cutlass supreme and am switching transmissions soon. I bought a tsi build turbo 400 and was wondering what all I need to do to make it fit. I know the yoke is different and I might need to lengthen the drive shaft. Anything else I need to know? TIA

 

The yoke is different and you need to SHORTEN the driveshaft. Unlike on the earlier cars, the e-brake cable does not need to change when moving the crossmember.

 

Also the t400 you bought needs to be for the BOP pattern- not Chevy.

 

You will also need a kickdown switch

 

I have a bracket for the kickdown switch if you need it, but I do not have the switch.
