Customer Reviews

See Why Dallas Drivers Trust Jaramillos Transmission

From quick diagnostics to complete transmission rebuilds, our customers count on us for honest pricing, fast turnaround, and dependable results.

Took my 2017 GMC sierra 1500 4x4 to replace the factory torque converter on my 6L80 transmission. Jaramillo’s transmission installed a new HD torque converter, transmission filter, new seals and even change the oil on my transfer case. Turnaround time was very good. Dropped off the truck and got it back the same day. Good pricing, Very knowledgeable. I highly recommended this shop!

They do very quality work at competitive prices. Customer service is excellent and is always great talking to them. They are the only shop I bring my transmission to now because as my hobby I restore classic cars. I would recommend them to anyone.

- Connor Spencer

Jesse was AWESOME at Jaramillo's. So kind and professional, they went out of the way to get us the best transmission at the lowest cost. They also worked fast to have my car finished in 2 days! So impressed, will use again!

- Maxwell Morrison

Jaramillo's Transmission is the best in DFW! They are a real Family business, and they treat their customers, and the vechicles they work on with respect.
