Paid to have a transmission rebuilt 03/31/2022. It is now 05/18/2022 and the transmission is not done. The owner, Jeremy, will not answer his phone or messages. No one at the place of business either. I am out $1000.00. Next step is to notify the police, file a report, and take him to court if he can not give us a call back.

Update: the transmission held up great a year and several thousand miles later until we sold the truck. It handled towing a large uhaul trailer cross country, and several other towing trips without issue. Shifted better than ever until the day I sold it. However, I did find out that the rear main seal (which is exposed when pulling a transmission) began to leak literally the day I sold it, came home to a puddle of oil where it had been parked. I cant say for sure if they replaced it wrong - its an older truck and I was using high mileage oils which swell seals to reduce leaks. So it could be from age, bad oil, bad luck, or a bad install and I cant say for sure. Still, i had a good experience and trust that if i was still local they would have taken a look at it. Jeremey and John were awesome. They were able to give me a estimate for my vehicle over the phone that was pretty accurate. It was half the cost of the dealer quote, with a comparable warranty to boot. My 2006 GMC truck was done a week early - they work on so many of their transmissions that they even had the parts on hand. They even put in a few upgrades to prevent any more issues down the line and no additional cost. Dont be put off by the shade-tree-mechanic look of their shop when you pull in - these guys know their stuff and are super passionate about their work.
