Extremely helpful, very easy to talk to which is rare these days. Given they did not make any money from me but still provided that high level of professionalism I had no choice but to leave this review. Highly recommend.

Today I popped by Action Transmission looking for knowledge. Even though they were busy, one of the gentlemen came out and assisted me immediately. He was patient and helped me figure it out and understand the problem. I was happy with the service and will definitely use them again.

Had a nightmare of a time trying to diagnose a couple issues with my supposedly rebuilt tranny. Turns out the previous shop did a shoddy job putting it back together after some warranty work needed to be done. Took it to Action and they re-rebuilt proper for me in really good time. I think they painted the trans case black for me too. Nice surprise. Very happy and impressed. If you got a ornery 47re bring it to these guys, they'll get it going.

So I called around for a problem with my differential and every shop recommended Jeff so I finally gave him a call. Right off the bat he was super informative and had me setup and ready for my appointment. My truck was in and out within an hour of my appointment time and he gave me a thorough breakdown and let me say, I've never had such a good experience with a mechanic before. 10/10 would recommend!Thanks for your awesome service!

Came recommended. they explained what they were going to do but said they weren’t for sure how long it would take until they got it opened up. They gave an estimate and said if they got it done quicker they wouldn’t bill me for the full price. I didn’t think they would, but they came in under the estimate! Work was well done and I also asked them to check a few things and they let me know it didn’t need to be done. I wouldn’t have known the difference and they could have made some more money off of me but they were honest. Ill be back.

Had a great experience with Action, probably some of the best customer service in the industry. They went above and beyond what was required of them and were very honest about the work they did and explained everything well.They also looked into an issue that was mentioned to them and gave feedback regarding it as well.Would definitely recommend as the service and price are some of the best around.

Honest, knowledgable, and friendly. These guys are the real deal. I've had several different vehicles repaired there throughout the years. The best Transmission shop around. You'll be dealing with one of the best if not the best transmission builder of our generation. Jeff is well known in the industry and often ends up fixing or helping to fix the vehicles that the other guys can't seem to figure out. Jeff and Bob are both guys that will go that extra mile to help out. They are fair and the rates are more than reasonable. This is the kind of shop you recommend to your friend's and your family. It's a small business built on quality work and a positive word of mouth reputation. I can't say enough about these guys. Stop in or call for an appointment. They'll take care of all your driveline needs. They'll even tell you if they notice any other issues and where you might be able to get them addressed. This is a 5 Star plus rating.
