The best pieces are factory C4 components that came along after 1970. The C4 is an excellent first time box, 2bands 2clutches nothing too cute. It is easy to get the springs backward, which results in prompt transmission failure. Hindrances to control pressure can cause slippage, heat, and wear. Kevlar makes very little sense for the street considering the cost involved and minimal benefit gained.
The intermediate servo and band are important to upshift quality and transfer of power. Note: There have been many engineering changes in this transmission since its introduction. Step-2: Install Governor The governor installs on the tailshaft. If you start out in second gear with this 1967-on pattern, there is no upshift out of second, which makes the 1967-on Select-Shift shift function differently than the earlier 1964—1966 Green Dot, which does upshift. New stamped-steel pans are available from Scott Drake Reproductions dealers. It is those details missed that come back to haunt later.

Another issue to watch out for is five- versus six-bolt bellhousings. However, fitment is tricky to impossible in compacts and intermediates, which leaves you with case-fill only. Always go with the best materials available for long life. 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. However, the eight-bolt valve body does not work with the nine-bolt 1970-on case.
And this is the only phase of C4 assembly where any kind of special tool or fixture is required. Performance Automatic has complete bushing kits for C4 transmissions. This Tech Tip is From the Full Book,. This type is for heavy-duty applications in full-size cars and trucks. On the street, you want longevity. Our Ford transmissions live up to the strong, durable capabilities that is expected from the vehicles that they run with. Valve bodies between 6F35 Generation 1 and 2 are also different which indicates the two are not interchangeable.
Flexplate Match Another important consideration is the size of flexplate and bellhousing you intend to use. I am looking to see what some of you redditors who have rebuilt transmissions before think are the best guides for rebuilding transmissions of this type? This means you are limited to the stepped-bell, case-fill C4 for your less-than-large Ford. This means there is an abundance of C4 cores available from 10 years of production so you can build the kind of transmission you need for street or strip. In few places is this more true than clutches and bands. The cause of transmission failure can be an important detail missed during assembly.
However, Torrington bearings, and modifications designed to accommodate them, do not come cheap. There is no leaking coming from the front seals, rear sears or oil pan. There are also many Ebooks of related with this subject. Lower the transfer case and remove it from under the vehicle. For improved performance, you want either the H or R servo and piston designed for full-sized Fords, or the C servo for 289 High-Performance V-8s. The manual also provides helpful information about operation, in-vehicle repairs and adjustments, overhaul procedures and more. When I ask transmission builders what they think of C4 versus C5 main cases, most take the C5 over the C4 when possible due to improved hydraulic circuitry and cooling.
This is why the R servo is more favorable than the H, if you can find one. Install the springs as shown here. Step-23: Apply Assembly Lube Install servo cover, piston, and spring with transmission assembly lube. Step-2: Install Roller Clutch Spring Retainer Roller clutch spring retainer also called a cage is next. This manual will show the disassembly and assembly of both the Generation 1 and 2 transmissions as well as component differences and transmission specifications. Take your time and definitely find a service manual to confirm it's going back together correctly.
First, you must establish proper throttle valve function. Lubricate the thrust washer with transmission assembly lube. Locknuts to 35 to 45 ft-lbs. A key to reliable assembly is being gentle. Treat those asking for help with respect, and answer without bias toward them, their situation, or their knowledge or lack thereof about the repair issues.
