Took my 94 Ford Ranger to certified and they fixed it for close to nothing. I had previously had a former transmission shop employee drive my truck and he said the trans would have to be rebuilt or I'd have to get a new one. Certified thoroughly looked at my transmission and did several minor things. It runs perfect and I do not need a new one! Service was excellent from Don and Tony to Cindy and the mechanic Barry! Would recommend them to anyone.
