Okay, I've got a lot of good info from you guys on my 4l60e so let me ask for some more.

Lots of you have suggested I need a shift kit because these things are prone to early wear. I've got a B&M 28 K cooler on its way. I won't be out trying to kill any ricers, or anyone for that matter. I don't need to hold any gear to any RPM and I don't need to downshift at any RPM. The Tahoe is the family ride but if the tranny is prone to early failure a little preventative medicine would be money well spent, I just want to get what is truly needed for my usage. It will likely end up pulling a 23" camping trailer a half a dozen times a year but that's it. It's been suggested I get the Transgo shift kit for the 1993-up 4L60E, P/N 4L60E-HD2

This B&M looks like it does the same thing.

This B&M sounds like it does the same thing just not the ability to down shift at any RPM or hold a gear to any RPM.

If I'm not looking for high performance, just to help reduce wear on the transmission, do I need the higher end kit? If it's needed it would be money well spent but if it's not needed for my usage why go there?

Thanks guys.
