    This is on a 99 Tahoe.

    I was under it the other day and just figured it was a 4l60e until I saw it. Didn't snap a pic but... It has a large pan and what looks to be a removeable bellhousing like a manual tranny.. Is it a 4l80e by chance? or are the 4l60's just a different looking tranny?

    This Thaoe came factory with a towing package and all the coolers on it.....

    Could be.. I just assumed they were the same as a 700r4 except that they were electronically controlled.

    they are almost exactly the same, except that the 4l60e has the removable bellhousing. at least that is what i remember from working at the tranny shop.

    the early 4L60E look identicle to a 700r4. then in 96, gm went to a removable bellhouseing on them. they also went with a 6 round pattern for the adapter/tail shaft just like the th400 and 4L80E.
