The part number location varies on C4 transmissions and is used to determine year of manufacture. They'll tell you what size you have, what platform, transmission type, and body type. The 4 speed toploader is one of the toughest manual transmissions ever built. When Ford Falcon and Mercury Comet were introduced for 1960, they were available with a new lightweight Ford-O-Matic 2-speed transmission. In 1970 the engineers at Ford gave it its first design changes. Models with an Automatic transmission used a C3 or C4 transmission all V8s used the C4. Both C4 editions have removable bell housings.
This tag contains all the necessary identification information and if not present, use the following visual techniques: the C4 measures between 17 and 18 inches long and has an almost-square pan with 11 bolts. Now what is the difference between the pan fill and the case fill C4's you might ask? Its pretty easy if you know what to look for. Too many motorists got this wrong and drove on the small dot, doing extensive transmission damage. They are the least desirable of the V8 T5 transmissions as the gear metallurgy, synchronizer design, and bearing arrangement were based on old technology. Typically, when you're dealing with your Mustang transmission, an expert is recommended for most major repair work. The heavily ribbed cast aluminum case serves as the home for fully synchronized 5 forward gears and reverse and features a 10-spline input shaft with a 28-spline output shaft.
This case is also ribbed for strength. For one model year only—1964— the C4 had a five-bolt bell-housing for V-8s only. All forward-speed changes are accomplished through forged blocker ring synchronized units. If you want purchase info on the complete C4 as well as other videos, just go to my web site; www. The modulator is located on the back of the case above the pan. C4 Transmission Identification There is not much to figuring out whether or not you are looking at a C4 transmission.

Instead, it used a redesigned valve body offering a P-R-N-D-2-1 shift pattern known as Select-Shift. The T45 was not used in the V6 Mustangs The 2003-2004 Cobra T-56 Manual Transmission The T-56 Tremec manual transmission is the high-performance option for your Cobra. For 1966, Ford introduced its own heavy-duty C6 3-speed automatic transmission for high torque applications behind large displacement big-block V-8s.
Im just glad they are Mustang exclusive! Suffix The suffix indicates the change level. Late Model Restoration has no affiliation with Ford Motor Company, Roush Enterprises, or Saleen. There have been numerous complaints from consumers about faulty performance. From 1971 to 1982, the C4 had a split-spline count. Editorial comments and layout are my own. Like in 1970, it was upgraded to handle more power and increase reliability. The 1-2 shift fork is shared between all 96-01 T45s.
Case-fill C4 transmissions are light-duty; the bell-housing bolts to the front pump instead of the main case. Like the T45, it uses a ribbed aluminum case with an integral bellhousing. Keep this in mind when selecting a C4, since the valve bodies cannot be interchanged between year ranges a 64-66 valve body wouldn't work on a 70-81 C4. By the 1970s, Ford had a respectable lineup of modern lightweight automatic transmissions.

In 1993, for the Cobra and Cobra R Mustang, the countershaft cluster gear recieved a special coating and the input bearing was upgraded from a torrington style to a tapered roller bearing. The input shaft is a 10-spline while the output shaft is a 28-spline. It also was used in the F150 until production ceased. It is most often found in 70's trucks and vans. The 3-4 shift fork was updated in 1998 thru 2001 and is a common upgrade for 1996-97. It features six forward gears with a reverse and the shifter is a remote mount design.
The angle between the bell housing and transmission case is much less than a case fill C4, maybe only 60 degrees or so. A C6 is easily identified by its one-piece bellhousing and main case design. The T-56 Magnum can handle 700 ft-lbs of torque. The speeodometer drive gear is the desirable 7-tooth. Over the years, as performance increased on manual transmissions, automatic Mustang transmissions followed suit. On some transmissions the tag may be located under one of the driver-side servo bolts.
