I crawled under there with a flashlight and found the number. This transmission is not desirable at all because of internal differences, like a weaker input shaft and oddball valve body. Tony K.

This article should give you a better grasp on the different types and uses of C4 transmissions. C4's were produced and used in production cars and trucks from to , when they were replaced by the three speed automatic transmission with lockup torque converter known as the C5. In this timeframe there were several versions, each with significant differences that, depending on your application, might make one better for you. From through , the C4's made had a 24 spline input shaft and front hub assembly, and with the lower spline count came a slightly smaller diameter on the input shaft. This year range is still desirable, as its case is identical to the case fill C4 transmissions, so the old 24 spine parts can be upgraded to 26 spline.

Ford had a fundamental challenge to its direction and future in the late s—how to shed a stodgy image and dated technology. This effort began with a new generation of skirted-block FE-series V-8 engines in In , Ford introduced its lightweight-iron Falcon and Comet sixes. The degree Fairlane small-block V-8s followed in The MX was a large-case automatic and the FX was small. Although these transmissions were rugged and dependable, they were heavy, complex, and not easily adapted to performance applications. This is when Ford engineers developed lightweight aluminum-case automatic transmissions for an exciting lineup of automobiles that arrived in the s. The 3-speed C4 Cruise-Omatic was introduced just in time for the model year. The — C4 was known as the Dual-Range Cruise-O-Matic due to its dual-range shift pattern, which included two driving ranges based on shifter position.

Seeing as we don't know a heck of a lot about Ford automatics, we abducted a variety of transmission experts and interrogated them for the following information. We found that like GM, Ford also made a number of trannies capable of fulfilling the needs of the weekend warrior, class racer, heavy hauler, and Sunday driver.

As the C4 evolved, other design changes were introduced. My Cart. But, they lack the overdriven gears and lockup torque converters the newer transmissions rely upon to boost fuel economy figures. So judging by this info, my tranny is out of a 68 mustang. Later versions had a transmission fluid cooler in the radiator. Then there were a bunch of C5's out there too, basically same as a C4 with differnet case-which is a little better from a performance standpoint. The angle between the bell housing and transmission case is much less than a case fill C4, maybe only 60 degrees or so. By the s, Ford had a respectable lineup of modern lightweight automatic transmissions. From to , the C4 had a split-spline count. Does this info tell me that it is in fact a C4.
