  Sam and Mike were very rude and refuses to work on my car. They clearly don't know what they are doing and are clearly trying to scam people without doing any sort of work. You can go to any other local mechanic shop in St Louis and not be treated poorly. 0/10 stars

  I can’t say enough about the excellent service and customer service! I was in and out. Up front with pricing so you know what to expect. Great locally owned shop!

  10/10 would not recommend. I took one of my vehicles here for a simple transmission rebuild (2012 Silverado.) The owner and service advisor were nice, but they need to double check the type of work their technicians are letting out the door. While I was doing normal maintenance on the truck a few weeks later, I decided to take a peak around the transmission and it was very aggravating to see the job I was given. 1. My factory exhaust was cut to remove the transmission (which does not need to be cut, just faster for labor time) and tried to weld it back in place, which is now left with an exhaust leak. Picture attached. 2. The vent tubing was not reinstalled properly. Picture attached. 3. The transmission was over 1 quart low on fluid, dipstick tube was never reinstalled correctly, along with bell housing bolts loose. 4. A few months later I was stranded at work from my starter not engaging the flywheel. To find out there was a bolt missing and the other one was loose. (Starter is removed to remove the transmission) thankfully I was able to tighten the bolt that was there and get to the auto parts store. 5. Around 40k miles later the truck would not move in drive or reverse. I called and was told it only had a 3yr/36k warranty and basically just “sorry.” I wasn’t going to post this review and just take this one as a loss but I’d hope someone reads this before taking their vehicle here. I imagine they just install transmissions from a reman supplier. This does not fix the known issues for these types of transmissions and leaves you stranded as I was. I thankfully found a reputable/knowledgeable transmission builder that got my truck back on the road in no time with a quality rebuild and great results.

  They ran up my coverage and left me with a problem that wasn't even the issue at all I'm hearing noise for my transfer and transmission

  I’ve wasted weeks with my car just sitting at this business. The men Sam & Mike just continue to lie and give me the run around. Def don’t recommend women trying to do business here! I took my business elsewhere where they wanted to actually work on my vehicle. Certified Transmission actually tried to charge me $9000 more than what I ended up paying. Took my business to Al’s in Edwardsville. Night & Day how much more educated and business minded Al’s is. I’m thankful I found a business that wanted to actually do the work and not make almost $10,000 profit!! Oh and the day Al’s received my car the got started working on it! Unlike certified Transmission who let it sit almost 3 weeks without a plan.
