If you have a 250- to 350-hp small-block or a six, a stock C4 with the standard complement of V-8 clutches sixes have fewer and a shift improvement kit delivers the kind of performance you need for the street. C4 corvette wiring harness diagram wiring diagram progresif c4 corvette wiring harness diagram library wiring diagram 1974 corvette engine wiring harness diagram c4 corvette wiring harness diagram. Another bellhousing fact that can catch you off guard is the wider C5 bellhousing used only on the 1982—1986 C5. Steel thicknesses also vary, which affects clearances. Expect to see E2, E3, E4, E5, and E6 Ford casting numbers on C5 cases. You want things real slippery for a good healthy start-up.
The production plant in was converted to production of the which was relocated from , as the Livonia facility was converted to the. It was primarily used with Ford's inline six-cylinder engines and small engines see , usually up to 302 in³ 5. The sun gear is held still by the intermediate band, which is locked around the reverse-high clutch drum. Expect some stubborn interference issues here. Note that is inch-pounds, not foot pounds.
Check fluid passages for debris. There should also be diaphragm and rod movement at 18 to 22 inches of vacuum. This means both stator support and forward clutch contact surfaces. Be very careful about seal lubrication and protection. In some instances, it is acceptable to use sealer, but only a non-hardening type and sparingly.
Kevlar bands work quite well for allout drag racing but make no sense on the street. For 1970-on, there was yet another revised valve body eightbolt versus nine-bolt along with a corresponding change in the transmission case. Valve bodies between 6F35 Generation 1 and 2 are also different which indicates the two are not interchangeable. To increase control pressure, throttle valve adjustment needs to be clockwise. Make sure this seal gets generous lubrication with either transmission fluid or assembly lube before shaft installation. Okay, You can use it as the reference content only. Because the C5 has a locking-clutch torque converter for improved efficiency, the converter is wider and, therefore, needs a wider six-bolt bellhousing.
Follow transmission case provisions for clearance and the low-reverse band goes right in. When line pressure is too high, shifts become harsh. There are no gaskets or seals here, just a snug interference fit. Transmission sump temperature should be at hot idle. We have the hard to find performance transmission parts all in one place and in stock. Always replace the bushing and seal. It bore the casting numbers E2, E3, E4, E5, and E6, corresponding with the year it was produced.
Experts and racers generally believe the blended pan-fill C4 case is the strongest C4 case; however, it faces space limitations with subcompact, compact, and intermediate Fords. Make sure the O-ring is thoroughly lubricated. The valve body bolts are torqued to 10 ft lbs. Note: the reverse planet carrier and reverse-high clutch cylinder are already assembled. The C4 Dual-Range is equipped with a valve body that allows a driver to start out in second gear on snow and ice with a 2-3 upshift, which is the small dot off detent next to neutral on the indicator. The Ford-O-Matic and Merc-O-Matic were available behind the 144-, 170-, and 200-ci straight-6 engines, along with the 221- and 260-ci V-8s, which came later in 1962. Internally, it has different valving and shift programming.
With the thinner than stock pan gaskets they are selling these days, I think 16 ft lbs is a bit much. Note: There have been many engineering changes in this transmission since its introduction. Covers transmission assembly, dis-assembly, diagnosis, and troubleshooting. Citroen c4 engine diagram online wiring diagram c4 citroen c2 citroen c4 engine diagram. The more friction surface you have going here, the better. One full rotation of the input shaft equals one full rotation of the output shaft.
This manual is directed towards the professional transmission technician, all builder notes and cautions should be adhered to in order to avoid mistakes or personal injury. 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. When Ford Falcon and Mercury Comet were introduced for 1960, they were available with a new lightweight Ford-O-Matic 2-speed transmission. First Gear Because the reverse planet is held stationary by the one-way roller clutch and reverse band, the output shaft ring gear then rotates around the reverse planet pinions. 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.
