Inliners International Forums General Discussion Drive Train 4l60e differences

I was at the junk yard browsing through the stack of transmissions when I noticed the different factory tags on the 4l60e transmissions. One had 8SHD on it, the other 6SHD, and 8FBD was on one that looked to have a Trailblazer bellhousing.

Is there any major differences between them all, or are they just designation tags for things like; van, truck, car, etc...

This may help:

Cool link. It looks as though the numbers have more to do with the year of the trans than anything else. Good to know though!

Thanks.

I've noticed while doing harenesses that the TRS is different between the model years. Little thing that could turn into a PITA down the road.
