All - I'm at the point in my 1963 Mercury Monterey Project that I'm getting ready to do a rebuild of the old Cruise-O-Matic Medium Case transmission. When I embarked on contemplating this rebuild I was shocked at the LACK of information. People always focus on engines - rarely on transmissions. So here is some background in case some of you are interested: In 1963 Ford Mercury used the Borg-Warner transmission. This particular transmission is from a 1965 T-Bird as identified by the warranty stamp: PCEBJ 39468. The Case stamps are C5MP 7006 A and DIF 24. The Medium Case Transmission is interchangeable with all parts for all years. They are not interchangeable with FMX (later Cruise-o-matic) or the Small Case transmissions. The Medium Case is NOT a C4 nor a C6 - just to get this out of the way. Reason for the rebuild: Owner was NOT a car guy and had no common sence. Suposedly "burned up" the transmission by driving it without changing or adding fluid. Parts can be found: Makco Transmission Parts LLC (email@example.com). Parts for rebuild: 106006C - Master Kit CI Medium Case 1955-1971 106034 Bushing Small (Med Case pump) 106064 Bushing CI Small / Med case 106034B Bushing Small / Med Case rear pump A106010C Filter CI Medium Case 1955-1971 Bands will be sent in for rebuild as exchange only is available. STEP 1: Pulling the Transmission If your transmission is already out - you are ahead of the game. Pulling a transmission is best done with a car lift, transmission lift, and a second set of hands. However - I did this with some common wrenches, two ramps, two jacks, and two standard jack stands. Get the car as high as possible. Disconnect shift linkage and downshift linkage Disconnect vacuum modulator on rear of transmission Remove dipstick tube: WARNING fluid will drain - over 10qts be prepared! Remove coolant lines (front passenger side rear passenger side): WARNING fluid will drain everywhere from these and for quite a long time! Remove Drive shaft -- removal from car is required on 63 Monterey Disconnect exhaust - both sides and drop down (can remove for better clearance. Remove Speedometer Cable Disconnect parking brake pivot assembly from cross member. Support transmission with a jack and disconnect cross member and remove cross member from car. I used a 1ft x 1ft square of plywood to distribute pressure from any single point on the bottom of the pan. Support engine with a jack. **NOTE** At this point the jacks are supporting the rear combined weight of engine and transmission - DO NOT REMOVE THEM ENTIRELY! Using a combination of the jacks tilt engine and transmission down about 20 degrees down. Remove four bolts that connect the transmission to the bell housing. Once removed the transmission will be free. Wiggle transmission gently from side to side while pulling on tail shaft. Transmission will come free --- gently lower and remove from jack and pull out from under car. **NOTE I am still on the rebuild phase. Others have suggested I remove the bell housing and converter from the engine - sources conflict on whether this is necessary. Some people recommend it for ease of mind - others state disaster will occur if you do not remove it - and still others say it is unnecessary work if proper care is taken on reinstalling the transmission. I will cover how I approach this later. Pictures are of the transmission removed and of the data tag. For those of you who wish to add advice / resources please do so. It took me a few weeks of research to find everything I needed. Hopefully I will be able to post a lot of pictures of the rebuild process. My co-worker is pretty gung-ho on getting this done - I may have to slow him down so I can take copious pics. Enjoy!
