ATI is a name I have known for decades, and I'm sure they please some of their customers some of the time. However, this is about my experience with their customer service. I needed a transmission controller for my 4L70E transmission. The 4L70E has different "flavors" that use different electrical connectors. So I wrote ATI, told them exactly which transmission I had, and asked which of their controllers would work for me, if any. This was the response: "Our references show that is [sic] is compatible with the 4L70E." Didn't say which of their controllers, and didn't inspire any confidence. Very poor.
Tip for consumers:
Ask their customer service a question or two BEFORE you buy, to see what kind of support you'll get AFTER you buy.
