Question: will lt1 t56 fit ls1?
Answer: The LT1 T56 saw its hay day from 1993-1997 before it was replaced by the LS1 version. ... He includes a new input shaft specifically for the LS1 T56 transmission, a new front plate and all the shims that you could possibly ever want. The part number you'll be ordering is "LT1/LS1," that's it, pretty simple to remember.
