Can't be happier with the professional, reasonable cost, and expedited care they gave us. Even felt confident enough to drive all of us to Dallas (200 Mi+) after the 5-hour drive home from Suwanee. Happy to report, it is running perfectly, and I will let my son take it back to college without any worries about the transmission. Absolutely top-notch service, they even got to us with a full schedule of other jobs. They included the warranty. There was an opportunity to treat us differently, but they helped us like family. Thanks so much for treating us so well. Couldn't speak more highly of an auto mechanic shop. I would recommend them to anyone. Thx. BTW, I am a very capable mechanic myself. I put a 1999 Dodge Durango engine into a 1964 Plymouth with a 1973 Dodge Ram 727 Tourqeflite, and a 1973 Dodge Swinger rear end, 3.91 Sure-Grip so I have some experience in this area. Highly recommended. 5+ stars https://williamstransmission.net/

Mark went above and beyond to get my old truck back in good shape. I called him to verify he did…read moreTransmissions, and after assuring me he could. He told me he was able to go get the truck himself, saving me the trouble of having a wrecker tow it in. He contacted me a few days later letting me know what the trouble was and what it cost, but also brought to my attention several other issues that would soon take the truck back out of action. I work from my vehicle so I told him to go ahead and complete the other work too. He finished everything in a prompt manner, and for a fair price. I will use his shop for my future vehicle repairs for sure!

so I took my 2006 dodge diesel to owner mark... was told he could rebuild transmission for 2500…read more.. well after it was all said and done it actually cost me 3,500.. was told I have a 1 year or 12k mile warranty.. after only 3 months and less than 2k miles later the transmission stops shifting entirely.. mark said he would fix the problem.. took it to him, after 3 days he called and said it was a mechanical problem and he would have to rebuild transmission AGAIN... 3 weeks go buy, he tells me on a Thursday that it will be done the following Monday, witch was yesterday.. so yesterday ,Tuesday morning, I call at 9am, he tells me it is a valve body problem and he should have it done soon.... later the day he calls and begins telling me my transmission is not the problem, he tells me I have a bad PCM causing the transmission to not shift... and that it wont be covered... so already not trusting him, I said I wanted to have and see a better explanation... in person he tells me my truck threw a code P2509.. witch is causing my problem... I took truck immediately to a dodge dealer and had codes ran.... P2509 Is a generic code for a battery not having a full charge and has ABSOLUTELY NOTHING to do with transmission.. dealer the ran a diagnostic on transmission and found that the TRANSMISSION Governor press sensor and solenoid was bad ... so in conclusion... this place is a scam, they lie, and don't honor their word

Stay away from this place if you value your time and money. This shop took 7 months to build a…read moremotor that I ended up taking to another shop to have fixed from the sloppy work done. Mark broke a bolt off in the main crank cap from the side. Then he did not put 2 bolts in the rear oil pane which goes into the LS rear cover instead he filled them with rtv silicone. When building a LS motor you have to use new head bolts because they are a torque to yield one time use but he used old bolts and charged me for new ones. Then he cut into the reluctor wheel while grinding on the crank so that had to be replaced. silicone was coming out everywhere so I could not trust it and I had to go to a better shop to have it checked. Motor has to be torn down and rebuilt, and parts replaced that Mark messed up. He thinks a person will not go through the trouble to sue him but for what I paid him and having to pay another shop to fix his sloppy work we will be going to court. There is alot of people saying the same thing and having issues with getting stuff done in a timely matter. Those good reviews are more than likely his people trying to off balance bad reviews. The review here on this page about a car breaking down at night and waiting until they opened is crap. Anyone really doing work with Mark is not getting anything fixed in that time frame so beware of the BS post here talking good about this shop. The crew je has now are not real trouble shooters so these posts are crap, The ine good mechanic he had died last year now he has guys going throught the motions with Mark being pulled in different directions to the piont the quality is no longer there. The review of the transmission repair is crap too he does not build or fix them. He might pull one and put one back in that someone else fixed but Mark does not build or work on transmissions so that review below is crap. The review the person posted here about going from California to Virginia is crap because this shop is no where near the highway for them to come off hwy 40 and find Marks shop out in the middle of Nicoma Park is absurd. There are many shops near the highway. Fake positive reviews. Cheap price is cheap work because you will end up spending more later to fix the work they do at Marks Machine Shop and Repair in Nicoma Park, OK. I attached pictures so you can see I am not lying.

After I got my truck back, the rear end started making noises and the driver side wheel was getting super hot. Took it back to them and it turns out that they overnighted the wheel bearing when they were reassembling it. They had to replace the hub assembly because the extreme heat damaged it. A while after getting my truck back, something snapped in the rear of the truck and it wouldn't move. Took it back and they said the carrier in the rearend broke. They assured me that it had nothing to do with the previous work they performed or had anything to do with the previous mistake they made with the over tightened bearing. Then they called and said it turns what had happed was the driver side axle(where that over tightened bearing was) snapped. Again, they said it had nothing to do with the previous work or mistake. When I went to pick my truck up, I asked again if the extreme heat from the over tightened bearing had anything to do with it and he said no. Then I asked for the old axle so I could have it looked at. He found part of the axle, but couldn't find the part that broke off. He looked around for a few minutes with no luck, then said he'd just text me when he found it. I told him it had to be around here somewhere and said I didn't mind waiting. After a while, it turned up. It looked to me that it broke off about where that over tightened bearing was. It had grease on it, so he put it in a plastic bag and took it out to my truck. I cleaned it off when I got home and it looks like it got hot at the break point cause it's a little discolored. The break point is also in the area where the hub assembly was damaged from the over tightened bearing. Maybe a coincidence, but it sure don't feel like it.
