Need to know if a 99 3.8 6 Cyl camaro transmission will fit up to a 98-02 LS1 V8?

 

It almost does. It is the same tranmission i think except for the bell housing. I think the bellhousing has to be bigger to hook up to the LS1. Either get a new bell housing or sell your tranny to get the V8 tranny, probably be less costly and less strenous.

I'm pretty sure about this, someone back me up here.
