What is a C6 transmission?

The Ford C6 is a heavy-duty automatic transmission built by Ford Motor Company between 1966 and 1996. It was marketed as the “SelectShift Cruise-O-Matic”. Compared to its predecessor MX transmission, the C6 offered lower weight, less complexity, less parasitic power loss, and greater torque capacity for larger engines.

What is the difference between a C4 and a C6 transmission?

The C4 transmission was primarily used in cars. The C6 transmission could handle more power. Due to the ability to handle more power, the C6 transmission was used in many Ford trucks with bigger engines, and in larger cars that were manufactured with bigger engines.

What’s the difference between E4OD and C6?

E4OD > C6. C6 is shorter so driveshafts change lengths. Trans x-member moves forward a few inches. Wiring changes from MPLS to the reverse and park/neutral safety switch is fairly minor.

What engines bolt to a C6 transmission?

What Engines Are Compatible With A C6 Transmission? With this transmission, Ford can pair their 351W, 351C, 428, 429, 460, and 462 gasoline V8 engines.

Are all Ford C6 transmissions interchangeable?

Any FE block C6 will work. Check the tail shaft for length. Late 60’s and early 70’s trucks had a short tailhousing with a fixed yoke on them instead of a shaft for a slip joint.

Will a 460 bolt up to a C6 transmission?

Diesel Trans to 460 Engine: For those of you who have a C6 automatic behind the diesel, it’s really just a 429/460-pattern case; throw away the factory-installed trans-to-diesel engine block adaptor plate, get a 460 Ford separator plate, and bolt everything directly up to the 460, using a 460-pattern auto trans …

Will a C6 transmission fit a 302?

If the transmission is out of a vehicle with a 460 (7.5 Liter) big block, it will not bolt up to a 302. If you are going to get a C6 it needs to be for a small block (302 or 351) and it needs to be a two-wheel drive model, a four-wheel drive model will not work with your 4×2. So yes it is true, that C6 will not work.

Does a C6 transmission have overdrive?

It’s the most advanced iteration of the three-speed Ford C6, but you need not perform major surgery** to gain some of its engineering superiority. Adding overdrive to a C6 is physically impossible, but the 4R100 can donate its forward planetary gear set for shorter first and second gear ratios.

Is a C6 a good transmission?

The C6 was produced with four basic bell-housing bolt patterns over its long production life and is a very rugged transmission designed for high-power applications.

Do I have a C6 or E4OD?

A look at the passenger side of the trans will tell you for sure. The E4OD will have a wire harness behind a metal cover towards the rear of the trans. The C6 will have no wires in this area. Also on the drivers’ side of the IP, a C6 will have vacuum lines, an E4OD will have wires.

Will a C6 bolt up to a 429?

You have to have a C6 of the correct bolt pattern. The 71-73 used a C6 behing the 351 and 429, other models had a C6 behind a 460. The FE bolt pattern is different. The case is more rounded on a FE C6.

Will a C6 bolt up to a 289?

Premium Member. The C6 will physically bolt onto either the 289 or 302 but I don’t think it will fit the 66 tunnel without some modification to the tunnel. It should fit the 68 tunnel fine, since a big block with a C6 was available that year.
