This causes the tranny cross member to be moved 2. The project was shelved with a design that lacked a dampener in the torque converter but after the project was revisited a dampener ultimately made its way into the final design. Pinto wagons are your best bet for one of these. For 1967, the C4 went to a more conventional P-R-N-D-2-1 pattern and a different valve body. Case and valve-body bolt patterns changed for 1970—1981, which is why a 1964—1969 valve body does not fit a 1970—1981 case. Aren't there any C5 trannies out here? These modifications are specified by one of the Ford engineers who designed the transmission. C6 Transmission Shift Better, Last Longer When it comes to transmissions, no other company provides this level of commitment to their clients.
In 1960, Ford introduced its lightweight-iron Falcon and Comet sixes. If there is fluid on the dipstick, check the manual shift valve, which is where control pressure begins. At the same time, it damages the pump, sending metal particles into the system doing further damage. To put a C-4 behind a 2. The B intermediate servo cover indicates mismatched parts because the B servo is for six-cylinder engines.
This Tech Tip is From the Full Book,. Check the through-detent upshifts by pushing the accelerator to wide open throttle in D and holding it there. Try to get a C4 that is a 'case fill' versus a 'pan fill'. These transmissions are built with improved shifts, better oiling and pump output. Case-fill C4 transmissions are light-duty; the bellhousing bolts to the front pump instead of the main case. Ford called its C4 the Cruise-O-Matic while Mercury called its C4 the Merc-O-Matic.
In August 1964, the C4 and the V-8s it was mated to were fitted with a larger six-bolt bellhousing to reduce noise, vibration, and harshness. Specifications call for above 12 inches of vacuum for all minimum throttle shifts. If you take your time, the piece that you trim out can be used to replaced the gap it will leave behind the shifter. With the engine running, listen closely for abnormal noise such as torque converter improperly seated, which can cause squealing, no control pressure, and an inoperative transmission. Check the kickdown shift points by pushing the accelerator through the detent at the appropriate road speed. As with just about any type of troubleshooting, begin with the simplest item first and work the problem from there.
We've also heard that the flywheel needs to be out of a 4. Ford first introduced an automatic transmission in the Fifties discounting the Hydramatic offered in 1949-54 Lincoln Continentals , with the three-speed Ford-O-Matic, in service from 1951 to 1968. This is where a step-by-step approach to the problem can help get you steered in the right direction. The C6 can withstand tremendous power in stock form, and has no inherent weaknesses, though they will rob power and are really suited to use with high horsepower big-block engines, because of their heavy rotating mass. Available for most Ford engines and applications.
Modified C4s remain popular with and due to their simplicity and durability. You will need the C5 torque converter and the C5 flexplate. We also carry custom installation components to fit 1967-1970 Mustangs for easy installation and conversion to overdrive, ask your salesman for details. How much power do you need it to handle? Does engine misfire or bog down under load? The C4 employed a new state-of-the-art Simpson compound planetary gear set, which became an industry standard in the years to follow. You can be methodical and cover all the bases during a rebuild and still things can go wrong. The clutch is applied and at the same time release pressure on the servo releases the band. The C5 was in production between 1982 and 1986 at the Livonia, Michigan, transmission and axle plant and is not recommended as a performance transmission as received from the factory.
The 3-speed C4 Cruise-O-Matic was introduced just in time for the 1964 model year. Searches elsewhere convinced me I have a C5 transmission. The C6 was produced with four basic bellhousing bolt patterns over its long production life and is a very rugged transmission designed for high-power applications. Giving the Transmission a better mechanical advantage and in turn, better take-off acceleration, slightly lower fuel consumption, and designed for better gearset strength. Operating temperature is 150 to 170 degrees F.
Unsourced material may be challenged and. Larger bellhousings accommodate a 12-inch converter; an 11-inch converter is found in the versions with the smaller bellhousing. Expect to see all kinds of mismatched transmissions. It offers faster engagement, quicker shifting, smoother operation, and increased service life. The C4 trans is very compact but very durable and has a long standing reputation for strength in a small package.
