Difference between 4L60E in Chevy V8 truck and Astro 4L60E?

[chemist]

Dumb question. Is there a difference between the 4L60E in a Chevy V8 truck and those found in our Astros? People on ebay are saying the ones out of Yukon and 1500 only fit those specific size V8 engines...

I don't believe there is any difference. My guess if any, would be the tail shaft which is easily swapped if need be.

I'm sure Locdoc and maybe others have the best answer, but I'd guess it would be the torque converter and maybe valve body that would be set up differently. I know lots of folks use the stock V-6 transmissions behind their V-8 swaps with good results. I'm not sure if it will work in reverse though.

Just a question I have...Is there a difference in the bell housing mount bolts between the 4.3 and the new LSx series 4.8L and 5.3L engines?

Yes, the ls series motors use the same 6 bolts, but add a seventh at the top of the bellhousing. This is also the case for the duramax diesel engines.
