My Adventra LX8 has done 340,000 km & has the original auto in it, untouched. It has done plenty of towing as well. I tow a rather heavy car trailer, best tow car I've ever had.
I'd be looking at fitting a trans cooler & finding another repairer.

I dunno, I reckon the 4L60E/4L65E are made out of cheese and carrots compared to the BTR, I blew the 4L60E in my Caprice at around 120,000km, lost 3rd and 4th gear.
Although I did rip skids in it and put it down the drag strip a couple times, on the last run it did the big flare on the 2nd to 3rd change
Then overtaking on the highway a couple years later, kick back to 2nd, then it bashed the limiter and suddenly no 3rd or 4th gear, only had 1st/2nd gear and no 3rd/4th.
If you're gonna tow with it then I reckon the entry level shift kit to increase the line pressures + a large trans cooler would be the go to make it live a bit longer.
