WHAT ABOUT HYDRAMATICS

At Mike's Transmissions we have the capability and parts in stock to deal with all of the tranmissions mentioned below. We have new coupling covers for the Jetaway in stock and a major supply of rebuilt front pumps. As Mike is a member of the National Cadillac-LaSalle club we do a major amount of work for its members. References will be gladly furnished upon inquiry. So if you're looking for top quality give us a call today.

Driveability — We are able to convert most single range hydramatic vehicles 1939 -1951 to dual range for driveability purposes. The single range always was jerky to a degree and the dual range is much more pleasant in operation.

Mike's history goes back as far as 1955 with the hydramatic. Having a 1940 Oldsmobile that developed a leak and being a teenager in high school, I couldn't afford to have it fixed. I pulled the trans myself replaced the front seal and reinstalled it. Needless to say it leaked like a sieve and I eventually junked to car and bought another. It wasn't until I started working in the field of transmissions that I was able to understand why I couldn't stop the leak. Today I know and I sure wish I had that old Olds back.

Hydramatics aren't all the same. General Motors calls most of their transmissions hydramatic. A little bit of History

The above transmissions were produced with the exception of the 400 prior to 1985 and since then there have been many, many more. So when you say Hydramatic it can really mean a lot of different transmissions. Hydramatic is actually the name of a division of General Motors that produces transmissions.
