Works great
Jaca (Commiefornia) | September 12th, 2025
Easy to install, doesn't come with any reasonable mount bracket. But I installed into a 1997 GMC k1500 suburban, the sensor itself threaded right in to the pressure test port. Real easy, took longer to identify the factory light wire to tap into. You'll also need some wire and connectors.
trans temp gauge

the product is fine but the shipping was ridiculous - It's probably because of the virus and the demand on FedEx, but it took a week for my order to arrive.
Worked well with my other Auto Meter Guages
