The 2 speed SP tranny on my 66 has given up or will very soon. This spring I plan to replace it with a T400 SP. My understanding is the converters for the T400's came from the earlier two speeds. Does anyone know this info for sure? My concern is whether the bolt pattern on the original flexplate will match the converter from the T400 SP.
Thanks,
George

 

The switch pitch converters for the TH400 are larger in diameter than those for the Jetaway. The bolt pattern on the flexplate should be the same, however.

 

Thanks Joe, always good info.

 

The same flexplate was used on the 65-7 330, 400 and 425 engines.

Thx guys, this is what I needed to know.

 

Hey George, dont know if you are interested but a guy in the next town over has one pulled from a working car. I bought the motor a while back and hes been trying to sell the tranny. I think he was asking $150.. Let me know if you are interested and i will forward your email add to him.
