My stock 4l80e is showing signs of age, slipping in third gear. It's in a 2500 Suburban, 115k miles, I have a 6400 pound travel trailer that I pull a few times a year, and a cargo trailer in that same weight range loaded, that I pull. This being AZ, the summertime temps are 110+, which makes things hot pulling up the hills (3k-4k feet elevation gain over 5-10 miles)
I'm thinking if I replace it, perhaps replacing it with a 6 speed from TCI Auto http://www.tciauto.com/tc/6x-six-speed-gm-automatic-transmission-850hphtml
Has anyone tried one of these six speed transmissions put into a 4l80e housing? Do you know if it's good for towing?
