My wife and I were traveling through Colorado on our way to my granddaughter's wedding in Cedar…read moreCity, UT. As we left the RV park in Colona and proceeded north through Montrose, we started to experience issues with the gears on my motorhome. We were at Townsend and 9th when the gears skipped to 3rd and we knew we were in trouble. The first transmission business we called didn't work on motor homes but they referred us to AATCO. We called and explained our situation to Missy. Missy got Lance on the phone and while he didn't guarantee he could solve the problem, he asked us to drive over so he could scan the device on our motorhome and look at our transmission to diagnose the problem(s). Lance truly saved the day! He found that a bolt had come loose and we had lost all of our transmission fluid. While some businesses might have put us off for a day or two or three, Lance and his crew got to work on our motorhome. They replaced the transmission fluid with several quarts, secured the bolt and had us drive around to make sure the problem was resolved. Sure as shootin ... Lance and his crew at AATCO resolved our issues in probably less than two hours and were able to send us on our way. Today is Wed., Oct. 8th, 2025 and even though this issue set us back a few hours, Lance made sure we'd make it to my granddaughter's wedding on Saturday. We initially thought the worse. We thought we'd be stuck in Montrose for another day or two and we thought we'd face a hefty bill for the repair. But AATCO's fee was incredibly reasonable and fair! I cannot say enough about Lance, Missy and the rest of the guys at AATCO except "thank you! thank you! thank you! for getting us on our way and for taking care of our transmission on the fly!!!!" I HIGHLY RECOMMEND AATCO if you happen to have any vehicle issues!!!
