Looking for many shops in Sacramento, found RTP transmissions the BEST in town! Literally! I had okay experiences with other trany shops in Sacramento. If you want quality work, good service, and respect. You come to Johnny! He is the guy who will take the time to listen to you and expand you understanding of transmissions. Brought in my 1999 f250 to get the trany rebuilt. Johnny explained every detail on what he was going to change. He also improved the transmission from common failures. Best money investment I have ever made in my life. Johnny is very straight forward and honest with his work! Thank you! Definitely recommend this place 10/10!!!

Very satisfied with the work I had done at this shop. I had a Mercedes and also a truck transmission rebuilt. Very trusted Mechanic and highly skilled, the timing and price was perfect Id recommend to everyone and rate 10 star. Thank you for the good work 👍

Excellent service and value and diagnostics. John did an amazing job replacing my clutch and other issues I had on my Tacoma. He found and fixed a problem that I was stumped on and now my truck drives amazing. Would definitely recommend

Great quality work at affordable prices!! Totally recommend this transmission shop to everyone!

Good 👍 👍

The attention to detail by this Technician is outstanding. John is a master of his work. He built a transmission for my Toyota that is bulletproof. Johns customer service was far beyond my expectations. Johns communication throughout my experience was great. He will get my business anytime I need it. Highly recommended! Thank you Sir for your expert work. This industry needs more people like you!

Transmission is working perfect I appreciate the time you put into it. Definitely recommend you to anyone I know that needs a trans done. Thanks John. Sincerely Ryan D.

The best spot in town to get your transmission rebuilt or worked on. John is meticulous and masters his craft. He is always reasonably priced as well. Don’t go anywhere else.

Rebuilt my 48rfe out of a 2005 dodge 2500 John is very meticulous. What more can you ask for than to have it hold up to high demand work. Good job John!Update...I guess I am the guy that can tear up a steel ball with a rubber hammer. Hauling to heavy of loads caused a tear up! I am luck John is super experienced and was able to get my truck in for a heavy duty rebuild! Lesson learned listen to the guy who knows, thanks again Mr John!

John built my 4R100 trans out of my 2002 Ford 7.3L. He increased the clutches in every gear, machined parts to update weak spots, replaced common failure parts with new updated ones, installed a billet cover triple disc torque converter, installed a custom shift kit, replaced my trans cooler, and installed my aftermarket trans filter all for less than then the other shops wanted for a stock rebuild. We talked several times before I brought the truck in and was always willing to discuss what upgrades and updates he could do for my trans. John knows how to build performance transmissions and is a true craftsman. From what I experienced he seems to really care about the product he puts out. Truck runs great so far, I am very happy with Johns service. I recommend anyone in the market for trans work, especially upgraded diesel transmissions, to consider him. Thanks John your hard work.

Great service and not expensive👍👍

Best Transmission shop in town! Bring your Cummins with that slippin transmission by and John will fix it up for ya!

Best service, nice work,
