I have pics of a th350 (i think?) and wanted to know how to ID them. I want to know what to look at and how to determine if its a usable tranny for a swap into a thirdgen. [I already know about using either the kit to use the 700r TS and the other option of using the long tailshaft to install.] Im more concerned about finding a tranny that can be used on either of those install options.

I have pics of a few connections on this thing. Why would it have an electrical input looking connector??

Anyway here are some pics, all info is appreciated....

Anyway to tell anything about convertors?

 

Long tailshaft unit?? 9"

 

the tranny in the pic is a th350 lock-up unit. the bell housing bolt pattern fits a small block or a big block chevy. the electrical connector on the drivers side is the connector for the torque converter lock-up. the switch on the passenger side i don't know what it is. i have not seen one on a th350. the tailshaft should be the long tail shaft. torque converters are usually best if replaced. you can't really tell anything about a tranny without taking them apart. without that it is a crapshoot. lock-up units are heavier than the non lock-up units. the tranny in the pics can be used for the application you want to use it for, but most go with a non lock-up unit for performance applications.

 

this may help
