This is the rudest most crooked people i have ever encountered!! Always read reviews before you do business because it would have saved us time and money! Lots of money! Our gmc truck started running bad and randomly shifting into neutral while going down the road so we were referred to Slawson Transmission. We had it towed there on May 21. We were told it would be 5 to 8 days. After a few days he tells us its not the transmission but our transfer case was messed up and driveshaft needed a longer one. He told us he would try to do just the back of the transfer case for $700 but if it needed the whole thing it would be $1300. He said he doesnt do driveshafts and we have had that same driveshaft for over 2 years and has never had a problem with it being too short so of course were like if the transfer case is the problem then fix it and the driveshaft should be fine since its never been a problem. After 2 weeks we he says they are just now getting it on a lift!! Which is outrageous!!! He says it needs the entire transfer case and would be $1500 which jumped $200 from the initial estimate. We said fine since we just needed it fixed and back! 2 days later he calls us to come pick up on June 5! He said he doesnt recommend driving it since the driveshaft is short which we have been driving it like that with no problems for years. We go in and pay and pull out of the shop. A few minutes later it starts doing the same thing again. I call them at the shop to let him know and he says its because it needs the longer driveshaft! Which is ridiculous bc its never been a problem. Its always been shorter and never affected the driving or shifting. He tells us to put a driveshaft in it and it will fix it. So the next day we buy a driveshaft and fix that and surprise didnt fix the truck still does the same thing. We were baffled as to what the problem could be. So we call him and ask if he replaced the speed sensor and was told yes but with a used sensor. Since it was used we replaced it with a new sensor and the truck drives perfect. After calling him he belittled us saying we like acting big and bad on the phone but needed to face him man to man! Not very professional when all i wanted was a refund for fixing things that wasnt the problem and costing us $1500! He told us he would only give us $50 for the sensor that he says he replaced. After reading other reviews they are obviously scammers and like screwing people out of money! I hope everyone Steers clear or reads reviews and enters at your own risk! We have filed with the BBB and will file a suit if nothing is done.
