I’m wondering if there is a specific trans mount I need in able to use the Spohn LS1 swap crossmember with my 2000 4L60e. I have two mounts and neither are quite right.

The mount I originally had on my 700r4 – the bolt on the bottom is not long enough.

The mount that came with the 4L60e – the bolt is long enough, but the diameter is too large.

I guess I could enlarge the holes on the crossmember but there isn’t that much material to begin with. Any suggestions?

 

Its designed around a poly trans mount that uses bolts inside, not studs like the stock rubber

Mod it or run a different mount, your call. Any will work
