The 5R55E, though mechanically identical to the 4-speed 4R55E, was a five-speed transmission, the first produced by an American maker. This valve body was used from 1967 to 1969. After mid 1989, used only in 4-cylinder Wranglers. It will effect a more firm feeling shift, therefore it is not recommended for those transmissions which specify Dexron only. The upgrade also included a matching clutch hub of 26-spline. It has 2 sets of bolts in the bell housing, 7 for the front pump and another 5 to attach the bell housing.
Beginning in 1967, Ford dropped the Dual-Range shift pattern for this traditional P-R-N-D-2-1 pattern and used a new name—Select-Shift. The B intermediate servo cover indicates mismatched parts because the B servo is for six-cylinder engines. Pack pump cavities with transmission assembly lube for generous lubrication on startup. Front planet gears rotate around the stationary sun gear, which is connected to the input shell. They all tend to have long input shafts compared to the Jeep and Ford T-18s. Step-6: Clean Clutch Frictions Always soak new clutch frictions in transmission fluid before installation.
There are different approaches as to how to build a C4 and what to put in it. The front planet pinions then rotate clockwise and the sun gear rotates counterclockwise. The larger six-bolt pattern right was conceived for the 1965 model year to reduce noise, vibration, and harshness while also providing improved strength. This mod also allows the transmission to be used completely manually. The last number is the last digit of the year.
Expect some stubborn interference issues here. Steels are driven by the clutch cylinder also called a clutch drum. Step-7: Install Forward Clutch Frictions Forward clutch frictions and steels installed. The sun gear is driven by the input shell, which drives the reverse planet gears. As the sun gear rotates counterclockwise, you get clockwise rotation of the reverse planet carrier.
The 1970 through 1981 case fill C4's also came in 157 and 164 tooth bell housings, but a new variant was created, the pan-fill C4. However, the valve bodies in the transmissions are different. My family has bought and will continue to buy Ford vehicles from Courtesy Ford! You can never have too much lubrication. The C-3 has a bay at the back on the left side. Step-3: Apply Yoke Seal Apply a thin film of Permatex Form-Agasket non-hardening yoke seal to the tailshaft. If you want fluid to run cooler, go with a cast finned aluminum pan.
Use plenty of transmission assembly lube on contact surfaces. Make sure driven gear flats are open to the torque-converter side. The C5 was produced in both stepped-bell and blended-bell configurations as well as 157- and 164- tooth flexplates. V6 version lighter duty than V8 version but can be modified to equal V8 version in strength. What made the little Ford-O-Matic different than its predecessors was its aluminum case and steel hard parts inside and out.
When power is applied, it flows to the forward ring gear, which drives the front planet carrier, which is splined to the output shaft. Seems everyone has a different opinion about how to build one for street and competition. Reverse planet drives the reverse ring gear and tailshaft. Unless you have a 1962—1964 221-, 260-, or 289-ci engine with a five-bolt block, you need the improved six-bolt C4 bellhousing. My best advice is to go with a 1970-on transmission case and valve body rather than try to mix the two. Some C4 and C5 applications have an O-ring instead of a gasket. Lube the seals prior to installation for best results.
The Ford Motor Company has produced a wide range of automatic transmissions in past decades and are sure to continue improving on the technology employed in their vehicles for decades to come. Most of you know Pinto, Bobcat, and Capri were never factory fitted with a V-8. Like the C4, C5s were produced as both case-fill and pan-fill with either 157- or 164-tooth flexplates. Applying too much torque distorts the governor, rendering it useless. If there is something that is particularly unreadable, drop me a note and I will try to rescan the item.
