GM 6L80 Transmission Information Thread

Just getting back to this Nick, thank you sir! I will ask for some specifics. Was just talking to my neighbor (ex-mechanic now engineer), he thinks the Billet torque converter is over doing my stock engine and for the amount of towing I do. I tow my bass boat once a week 30 to 100 miles. Its maybe 3500lbs. The Tahoe is currently a little sluggish while towing the boat and would like some pep. Thoughts? Thanks again.

$2800 is for a complete overhaul, torque converter plus $1200 r/r so 4$k...not bad if so..

Yes sir. Aus-Tex Transmission. They have great reviews and seem reputable.
Am I overdoing it by getting the Billet torque converter?

I hope this is the correct place to ask this question, if not I apologize. I just had my 6l80 transmission replaced on my 2007 Yukon Denali with 147K miles by the chevy dealer Bill Roberts Bolivar MO, for $5600. When I got it back yesterday, I tried the manual shift mode and it does not do anything. I called the service advisor and he said that had nothing to do with the transmission, that it would be a problem in the buttons on the column. So, if I take it back it will be more money. Should I try to troubleshoot myself using the videos and 14 pages of posts on this forum, or should this have been part of the replacement?
