Service: 10/10 My primary contact was Mike, however I spoke with many other staff in person and over the phone over the course of a week after I had my Crosstrek towed in with a destroyed transmission system. Everyone was courteous, helpful, and responsive. The new transmission they procured was practically brand new and installed professionally. The experience they provided me as a customer was as excellent as the final bill and they are now my go-to shop for transmission and suspension work. Thus, I strongly recommend this business. When I had my car towed in, it was after hours, but conveniently they had an overnight key/car drop off system that was secure and easy. The lobby was clean, organized, and offered free cold water.

Had my vehicle being serviced at local mechanic and they notified me that the PTU (Power Transfer…read moreUnit) that is part of transmission on all-wheel drive vehicles was leaking badly and needed to be replaced. They did not work on transmissions and advised me to take it to a transmission repair shop. Called the Ford dealership and they told me to replace it would run around $3300. For comparison I called some transmission shops and got ahold of County Transmissions and spoke with Hampton. He told me that it would run $2300 including labor if it needed to be replaced. They had good reviews so I decided to take it to them and save the $1000. Took it there on a Monday and Hampton told me they would have it done in several days. By Friday had not heard from anyone so I called them and was told that it was next in line to be looked at which would be the following Monday. My vehicle had been there five days and had not been looked at. On the following Monday, Hampton called me and said that it did need to be replaced and to replace it would run $3200. This was $1000 more than $2300 as he had initially told me and about the same as what the dealership would charge. Mentioned this to him and he said that the $2300 was for a used PTU that they would get from a salvaged vehicle, and a new one was $3200. He had not told me this when I first called and I had of course assumed the initial quote of $2300 was for a new one. Didn't even know they would consider putting a used one a vehicle because how would you know it didn't have issues. In light of this new information and for the fact I feel it was a bait-and-switch, I decided to take my vehicle to the Ford dealership and have them do the repair. The dealership's warranty on the PTU was much better and I know am getting a genuine Ford part. With an independent shop am probably getting a cheap aftermarket part. If I moved to another city or say was traveling and had an issue with it, I could take my vehicle to any Ford dealership and they would honor the warranty. If County Transmissions had done the work, then I was out of luck. Had to take an Uber back to County Transmissions and pick-up my vehicle and then take it to the Ford dealership. This costs another $50 on top of the $50 Uber charge had already incurred when I took my vehicle there and had to take an Uber to get back home as I live far from them. I opened up my SmartTag GPS tracking app as had placed an Android SmartTag GPS tracking device inside the vehicle awhile back. Was very surprised to see my vehicle had been driven around Vienna and appeared they were using it to run errands as it was stopping at various locations. So in the end I was out $100 in Uber fees, they had my vehicle for a week and nothing was done after Hampton telling me they would get to it in several days, plus they apparently used it to run errands. I would certainly not recommend this company in light of everything that happened. Note: Saw that Hampton had posted a rebuttal on my initial review where he states that the initial quote was an estimate to repair the PTU, but this is not true. The PTU is something that is replaced, not repaired, and he gave me a quote of $2300 to REPLACE the PTU. Plus they didn't need to be driving it around to determine where the leak was coming from since it was obviously leaking when I took it in and it had to be replaced. When I called him on Friday he said they hadn't looked at it yet; however they had been driving it around before that Friday. He mentions that they have a shuttle service and I asked about this but was told it didn't go to where I live.

My husband and I had Kenny a mechanic at John's Automotive rebuild a Transmission for a 2001 Ford…read moreF350 Diesel. We were told that he would rebuild the entire transmission and that he would even upgrade the torque converter for us. My husband gets a call after he already has our transmission and Kenny tells us that they couldn't locate a new solenoid for the transmission and we would have to buy one and bring it to them. Next, we think all is good he had "rebuilt" it and was good to put into the truck, we get the transmission and realize it had the wrong torque converter in it. Kenny's wife tells my husband that he has to bring the transmission back to them as they messed up and put the wrong torque on it and another customer was bringing our torque converter back to them as they had mixed up another customers with ours. My husband drives an almost hour from Lusby to switch out the torque converters he then comes home goes to install the transmission in the truck to realize when he put the transmission fluid in, Kenny had installed the wrong gasket and 90% + of the transmission fluid we had just bought was on the ground. That was 16 out of 17 quarts that the truck took. We then went to Advance and had to buy the correct gasket to install. Mind you we had already spent $1,200 for the rebuilt transmission, $120 for the solenoid (that should have been included) $100 in transmission fluid and now $25 on the correct gasket (again which should have been included). We finally get the transmission in, with the correct gasket and it goes into 1st and 2nd gear as well as reverse, but it won't go into drive. We call Kenny only to be told it's an electrical problem. He then stops responding to my husband so I reach out as a "different" customer as a referral and of course I get a response. A few days later, Kenny his wife and a friend of his all come to our house and "look" at the transmission. They "confirm" it is electrical not the transmission that they "rebuilt". At this point we have spent everything we have to "fix" the truck as we don't have much money. A few weeks pass and we are finally able to get it to a mechanic for an inspection and low and behold we are told the transmission needs to be completely replaced. Hmmm we just had it rebuilt!! Inspection is another $140 to the price.... We get a 2nd opinion cost $120 and the mechanic looked at all the electrical work and says the transmission was not rebuilt. He gives us the codes he pulled up which says "NO FORWARD CONDITION WILL BE CAUSED BY ELECTRICAL OR SOLENOID FAULT AND WILL NOT SET DTC's SUSPECT FAULTY LOW SPRAG OR FORWARD CLUTCH. PLACE SELECTOR IN 1ST, IF VEHICLE MOVES SUSPECT LOW SPRAG FAILURE. IF STILL NO MOVEMENT, REMOVE PAN & INSPECT FOR CLUTCH MATERIAL (FROM FORWARD CLUTCH.) The truck of course would not go in gear. Kenny responded at that point and said to pull the transmission and bring it back to him. He and my husband could look at it together. We pulled the transmission and there was gray sludge and metal flakes in it. My husband sent the picture of it to Kenny and have not received a response from him since which was 2 days ago. We have spent alot of money still for a truck with a transmission that doesn't run. I would not recommend this shop to anyone. We put out way more money than intended to "fix" what they said was already fixed, however they did not fix it. If I could have given a 0 star I would have! These people are horrible! Do not let them do work for you!!
