2004 4x4 avalanche 4.11 rear differential rebuild Pleasant to deal with and got an estimate up front for my approval. 12 month parts and labor warranty. I was surprised that that they re a full service shop and can do just about anything. Talked to their mechanic and was impressed with his detailed knowledge. I am going to use them again.

I am so happy that you provide this… I am so happy that you provide this essential pre purchase service. Car owners do not really know the condition of the car they want to sell.

Looks out for the customers. Very friendly and knowledgeable staff. Kenneth answered all my questions without any hesitation. He took my truck in right away and when I got It back, it ran like a new truck. I would recommend Cottman Transmissions to anybody that needs auto work done right.

This business and family are simply THE… This business and family are simply THE BEST!!! I had severe transmission failure in my ‘86 Winnebago on my way through town, and was afraid it was gonna be real hard to find anyone to work on it. Betty Ann was exceptional with her knowledge and attention to detail with what needed to be done, while Clay (master builder) rebuilt my transmission back to perfect condition. They went above and beyond to help me in my stranded state and were more than fair with cost and time it took to complete the job. I’ve made mechanic friends for life with Cottman Transmission and recommend them highly to everyone!! Simply, THE BEST!!

Highly recommend!! Great communication,detailed explanation of service rendered, fair price, good follow up. Everyone at Cottman was fantastic. I will definitely be returning and recommending them to all of my friends and family. Thank you Chris and the rest of the team!!
