I have a blazer with auto trans 4L60E. How complicated is it to drop in a carbed SB 400? Specifically, how is shifting, Rpm, Trans pressure, speed etc. controlled?

 

Didnt somebody just ask a similair question recently?Guys you cant run a carbed engine with an eletronicaly computer controlled trans unless your willing to mod your wiring harness and whole bunch of $ and work.pre1st gen and 2cnd gen dont mix.There different beast.If you know alot about wiring and schematics you can get a 94-95 trans and ecm from a gm truck of the same year.The trucks have there own seperate control modules for the engine and trans.
