“Good company. Did some business with them back in 2011 or 12?? They were awesome then and still awesome now. This order this time around took a bit to ship so I emailed them and they were quick to get back to me and shipped my items out that same day. Great company, great staff and great service.”

“The man who picked up the phone was helpful but could not check the product for damage before it left. I also requested directions for the install and there was none available. They sent a QR code for directions with the package and it was a bad link. Be up front and change the picture to a non- powder coated housing. This is false advertisement on the website.”

No worries at all! Could you please reach out to us directly through our website or customer service line? We’d be happy to help you find the exact part you need and get it sorted out for you! 😊

Emailed a confirmation that everything was correct and asked if i needed any further assistance. Absolutely recommend this company and the conversion to anyone with a dodge transmission.”

“The ATS Thermal Bypass Valve was suggested by a co-worker a few months ago. I looked it up knowing that the 68rfe has always had problems. I was already having about everything you could buy for a 2021 Ram 3500, installed. The bypass valve sounded good and was inexpensive so I bought it. The delivery was quick and the installation even quicker. So far I have seen 30-40 degrees cooler transmission temperatures, although I haven't pulled my trailer yet. I am happy with the product and have suggested it to multiple friends.”
