Greg is amazing. Ive used him the times now over the past 5 years. Great quality work and goes above and beyond. Very fast. Great prices. All around the my go to mechanic.

Greg did a great job. Weve had him fix our transmission and a few other things on our diesel truck. Does great work for a fair price. Definitely recommend him.

Greg is the best and most affordable mechanic in Greeley. He knows how to diagnose the problem right and fix it the first time. Only auto repair that my family will go to.

Went in for valve cover gasket on a v6 only the front was completed, never have I known only half the job to be done and charged 2 hours for a 15min job

First time here was recommended by a friend! Greg is very professional told me what my truck had right away told me how much and how many days, straight to the point. Finished the work as promised and Greg told me to bring it in 10 days later to check it for warranty to be valid, took it in was awesome checked it and told me everything was good! Truck feels amazing after he fixed my transmission, this is my mechanic going forward!!! Ford F150 transmission rebuild.

I love doing business locally and particularly with someone who knows his industry. Highly recommend.

Great service, fair price, very knowledgeable, and good sense of humor lol, its one of the few places in town that can rebuilt a rear diff in house. Very happy with the results.

Awesome company, although of happy customers here.

Greg is fantastic. He gets my cars in quickly and back to me quickly . He is always busy which I take as a good sign but sometimes takes a couple of days to get in. No complaints whatsoever on my part though. He calls before he does any work and always gives you your options on what you can do and very affordable. Im so happy I found this place and will be using him for years to come.

Greg was able to get my truck in right away and had it diagnosed and fixed the very same day. I couldnt be happier seeing how other shops in this town couldnt even figure out what was wrong with it. Unfortunately I wasted time and money with other shops but now I know who to go to! He takes pride in what he does and knows how to communicate with his customers!

I always take my car here. When I first moved to Greeley I had a very difficult time finding a reliable mechanic. Everyone I found was overpriced and could not fix my car in what I felt was a timely manner. I am a delivery driver, so it is imperative that I have my vehicle in good running condition and available at all times. Not only is Greg a great mechanic providing excellent customer service, he is also understanding of my situation. If you are someone like me who needs their car promptly without breaking the bank then this is the place for you!

This guy does amazing work and fixes it the first time right .

Greg is honest and fair. He communicates well and I trust his work. I would recommend him to all friends and family.

I just had my vehicle repaired for the third time by AA Transmission (clutch, starter, and radiator replacements). Gregs service is extremely fast, super friendly, and relatively inexpensive. Spread the word and give this man some business.

Greg, helped me out very quickly and his prices were affordable. Hes is awesome, look no further.

Greg is a great mechanic! Very knowledgeable! Got my car fixed!!I recommend this shop

Amazing service, job was affordable. My 2000 Dodge was having problems with the engine and Greg found the problem with ease. Great family-owned business.

Greg was very polite and they got my truck in very quickly and had it diagnosed quickly. I would highly recommend taking your vehicle to A A transmission.

Went to his shop today to get carrier bearings replaced and seen that the tranny mount was broken to so he replaced all of it for me Greg is honest and very respectful and has very good pricing and gets right to work on your vehicle I highly recomend his services

Very professional service and reasonable prices!!...highly recommended

Zero Stars. Took my car there for this guy to work on and he did work without my permission and then tried to overcharge me for parts and labor, when swapping out the new one he put in without my permission took less than 30 minutes. If I had realized this is considered business fraud in the car industry, I would have called the police and demanded my car immediately. He is lucky I did not realize this. He was attempting to force me into paying by doing the work without permission. Very fraudulent guy. He put the old part back in and I drove off. Sadly I should have drove off with the new part because could have with absolutely no repercussions. I have filed a complaint with the 19th District Attorneys Office concerning the Automotive Repair Fraud Act of Colorado.

Greg is a good mechanic with very competitive pricing. Took my truck in to get diagnosed and he managed to diagnose it and fix it all within a couple hours.

They fixed my 08 Silverado affordable prices I do recommend them

AA transmision was about the best in town and reilable fare priceing i called to get my tranny done in a dodge 1500 gave me a good price had it done and back in my hands in 5 days very nice people. greg is a awsome tech. i would use him again.

Greg replaced the tranny in my 2004 GMC Envoy at 211k, about 18 months ago. Ive put 11k on it since. No issues whatsoever. Greg showed me all of the damaged parts in the tranny and used higher end products for replacement. Just a great experience.

Good work but hes very expensive

Great mechanic. Trustworthy.

Very good service and very fast

Called at 10 am sat morning couldnt get me in for a simple oil change.

Good shop
