Our Services Include

Tranmission REPAIR
For over 20 years we’ve been repairing transmissions to keep you moving. With our honest pricing and guaranteed repairs, you can trust Cottman for your transmission repair. Don’t pay for a new transmission if a repair will suffice.
Clutch Repair & Service
We check your cars clutch and hydraulic system to see whether it can be fixed with a simple adjustment, slave or master cylinder, or if the clutch assembly itself needs to be replaced. Either way you’ll get fair honest pricing and the Cottman Guarantee.
Transmission Replacement
At Cottman, we fix transmission problems; it’s been the hallmark of our business model since 1962. That usually means repairing or rebuilding your transmission. But sometimes a repair or a rebuild just isn’t your best choice. Sometimes a better choice is to replace your transmission with a remanufactured one, or “reman.”
Driveline Repair & Service
From the flywheel to the axles we’ve been specializing in driveline service and repair for over 20 years. We’ve stayed on top of the latest advances in driveline technology, with state-of-the-art training and cutting edge equipment.
Transmission Rebuilds
We build in the very latest updates, to bring your transmission beyond like-new performance. We use the finest parts available, and make sure that every transmission we rebuild is set to the “sweet spot,” where it can perform at its very best and keep performing that way for miles.
Transmission Flush
Sometimes it’s called a transmission flush; other times it’s an automatic transmission fluid exchange. Whatever name you prefer, it’s a real service with real value that can help add years to the life of your automatic transmission.
