4L80 vs 6L80 bellhousing size

Hi all,
I don't have or know anyone with a 4L80 so I was wondering if anyone knew if there was a difference in the bellhousing size of the 4L80 vs 6L80? Thanks in advance.

Ben

Re: 4L80 vs 6L80 bellhousing size

Hey Ben, the bell housings are the same size I believe. What is larger is the case just below the housing. On the 6L80e bell housing it doesn't get as small at the shifter linkage are as the 4L80e.
I can get you a picture of a 4L80e but would have to be later tonight.

The picture is the rear view of a 6L80E

This is the rear view of a 4L60E.
Not sure this helps but thought I would add it.

Maybe this will explain it.

It went into a c10 with a 2 piece drive shaft.

Thanks for the help all, they appear to be the same size or at least very close.

Much appreciated!

Ben
