We limped back to a local KOA for the weekend while Jon and Rose searched for a re-manufactured transmission. "Nothin' local" We decided to hang out at a great KOA for weekend and Darrell & Bonnie fresh back from two weeks vacation started on rebuild after Jon with SOME help from me removed unit from RV.

This is not the first time I have relied on NATCO Transmission for service. And will not be the…read morelast. This place just recently changed ownership, and the new ownership had a very high bar to achieve just to maintain the service excellence I had received in the past. My 2021 suburban with GM's pathetic failure of a 10 speed has been having shifting issues for a long time. I had taken to the stealerships a few different times while under warranty and ofcourse they claimed it was fine every time. Now that the warranty expired, if failed. GM, of course, is refusing to make things right - so while exploring legal action, I still need to get it back on the road. So I brought my Suburban to Shaun (the new owner of Natco). Shaun and his entire team took excellent care of me, made the repairs and got me back on the road. They have secured theribbon of excellance !! Thanks to all of you and NATCO.

Today I stopped in spur of the moment because my Subaru Forester was making a racket due to a loose pipe that would not stay on it's bracket. In less than 20 minutes, they had fabricated a permanent fix for my problem and didn't even charge me. Last year, they replaced a heat shield at substantial savings after explaining my options.

Just 2 miles of Hinckley, MN (on Hwy 35) our wipers hit each other and the driver's side (of course) wiper got caught and bent up and looked like a triangle, not a blade. 2 miles later we turned off the highway to look for a wiper. When my hubby spotted Slim's, he decided he'd rather pay to get a new one installed than buy one & try to get it on himself (in the wind/wet snow) & said he'd probably be fighting with it for a while. We pulled into Slims and one fo the guys took a look at it, looked at their stock for wipers & found he didn't have the right size. He called Napa and had the correct size delivered in less than 5 minutes. He installed it and double checked the wiper action for both. Seeing that the other one was running too close, he also adjusted that one. $20.00 later with great service and a quality wiper, we were on the road in less than 20 minutes total. Was impressed enough that I decided to write up a review the same day. Thanks to the guys at Slim's Service. PS. We got some gas too, even though we still had 2/3 of a tank. We had no problem with the gas running slow or the pumping action. I used to have a car that had that problem but it was the angle of the piping in the car that lead to the gas tank & let the gas bubble. That happened at many stations. Our Kia doesn't have that problem at all.
