Although these transmissions were rugged and dependable, they were heavy, complex, and not easily adapted to performance applications. Expect to see all kinds of mismatched transmissions. These websites are updated sixteen hours per day seven days a week. In addition we build custom Torque converters for the C-4 in all sizes and stall speeds right here in our facility and like our transmissions, are custom matched to each application. In August 1964, the C4 and the V-8s it was mated to were fitted with a larger six-bolt bell-housing to reduce noise, vibration, and harshness. Make - Ford Length - 28.
There were C4 transmissions with pan-fill dipstick tubes blended case and bell-housing with 164-tooth flex-plates. This is when Ford engineers developed lightweight a l u m i n u m — c a s e automatic transmissions for an exciting lineup of automobiles that arrived in the 1960s. Deep first gear with direct-drive in fourth. Your risk from exposure to these chemicals varies, depending on how often you do this type of work. Too many motorists got this wrong and drove on the small dot, doing extensive transmission damage.
The C4 employed a new state-of-the-art Simpson compound planetary gear set, which became an industry standard in the years to follow. Make - Tremec Ford Length - 9. Written by George Reid and Republished with Permission of CarTech Inc. 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. The transmission is very popular in the sport of drag racing today, with units equipped with manual valve bodies and transbrakes, some of which are air shifted.
Ford called its C4 the Cruise-O-Matic while Mercury called its C4 the Merc-O-Matic. We look forward to serving you. Weighing in at 200+ pounds. Make - Borg Warner Length - 9. For 1967, Ford did away with the Green Dot Dual-Range C4. Borg-Warner did most of Ford's automatic transmissions prior to that.
Close-ratio first gear and overdrive in fifth gear. This article relies largely or entirely on a single. 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. Comes with our own heavy duty torque converter with tig reinforced internals with stall speeds up to 1800rpm. Please help by introducing to additional sources.
It does, however, have a reputation of greatly reducing performance as well as fuel mileage, due to the amount of power it requires to operate. Bellhousing and main case were cast as one to reduce weight and reduce the likelihood of leakage. At a glance, the Dual-Range valve body looks identical to 1967—1969. Because automatic transmissions encompass dozens of tiny parts—clips, balls, pins, valves, springs, and other items—your workspace must be well-lit, neat, orderly. Fairly low first gear with overdrive in fifth-gear. From 1971 to 1982, the C4 had a split-spline count. There are actually two numbering systems.
These design goals were in line with those of the C4 for smaller engines. This gave it the capability to handle 475 ft-lb of torque. We work with different manufacturers in the development of stronger parts. Case-fill C4 transmissions are light-duty; the bell-housing bolts to the front pump instead of the main case. In practice, it is quite complex and has been worked out by powertrain engineers determined to give you smooth and reliable operation for at least 100,000 miles. Close-ratio first gear with direct-drive in third-gear.
We can supply all varieties of C4 including both case and pan filled models, V-8 and 6 cylinder applications as well as early and late variations. It got new composite plates and valving. For 1971—1981, the C4 valve body changed significantly and does not interchange with 1964—1969 bodies due to changes in the case. Thanks to Tom, you were Great to speak with, you are a asset to your company and you project a honest caring concern to those with a problem and you are willing to try and help. Most C4s were case-fill notched case and bell-housing with 157-, or 148-tooth flex-plates.
Instead, it used a redesigned valve body offering a P-R-N-D-2-1 shift pattern known as Select-Shift. We can provide either a new or used bellhousing if required at additional charge. I promise you that the next transmission I have to replace or any other person I hear of needing a transmission I will be heavily promoting Monster Transmission and tell them that I personally use Monster Transmission. These chemicals are found in vehicles, vehicle parts and accessories, both new and as replacements. Alth-ough the C6 has a completely different case and internal components than the C4, it is virtually the same internally to the C4—on a larger scale for heavy-duty use. In early applications, the Ford-O-Matic transferred heat to the atmosphere via the torque converter and cooling vents in the bellhousing, instead of using fluid as coolant and a transmission cooler in the radiator. It is important to understand that part, casting, engineering, and service numbers rarely match each other.
