Some C4 and C5 applications have an O-ring instead of a gasket. Remember, the throttle valve is important to transmission control pressure, which means being careful with how you make adjustments. The best remedy for this is to start the vehicle in park and then immediately shift to neutral. Engine power travels through the forward clutch to the forward ring gear hub and ring gear. This often explains why you needed to add fluid occasionally yet there was no leaking on to the ground. There were two C4 shift patterns employed during its production life.
The governor signal is created by the rotation of the output shaft, which throws the governor weights outward and sets up the proper pressure I'll go into more of the pressure relationships in the modification section. Since direct drive is the only other time the front clutch is used, and the vehicle is already in motion, no extra holding power is needed to sufficiently lock the front clutch drum. Kevlar makes very little sense for the street considering the cost involved and minimal benefit gained. The Torque Converter There has to be something to transfer motion from the engine to the transmission and that item is a Torque Converter. To be honest a rear wheel drive transmission isn't much different as many of the basic components are the same.
The staff has been amazing to work with and takes care of their customers better than any other company I have ever dealt with. Eventually, that crud will be pumped out into the new transmission. When the sun gear and the front annulus gear spin at the same speed the planet carrier has to rotate at that speed gear train rules dictate that when two members of the same gear rotate at the same speed, the whole gear set rotates at that speed. Remember to keep your Chrysler service manual handy and follow whatever kit instructions you finally decide upon. Always go with the best materials available for long life.
Seems everyone has a different opinion about how to build one for street and competition. The C5 also has a deeper pan than the C4 along with a corresponding pickup. Step-11: Install Number-7 Thrust Washer Number-7 thrust washer goes on this side of the reverse planet carrier. However, the shock of 4000 to 6000 rpm drops on the starting line created enormous loads on tires and driveline components. 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 splines on the left fit into the front planetary gear, while the second set locks the output shaft to the rear annulus gear and the third set holds the governor-park pawl assembly on the shaft. Does the throttle valve work properly? This low pressure in park keeps the converter from completely filling and loading the engine unnecessarily.
The output shaft is shown with its thrust washer on the left; it prevents wear between the input shaft and the output shaft. Install the shaft, gently working them into the governor distributor. Many thanks to David Frey, Vicki Milley, Debbie Hoflo, and a very special thank you to Tom Mallot for his photographic help. Kickdown valve top is depressed by the kickdown linkage at wide-open throttle. Identification can be determined through Ford casting numbers, date codes, and visual identification of these components.
I'll incorporate that into the modification section. The front planet pinions then rotate clockwise and the sun gear rotates counterclockwise. The rear clutch is on in all forward gears. . No hydraulic units are operating and, with no clutches or bands applied, the input shaft-front clutch hub assembly and the driving discs in the rear clutch pack are rotating at engine speed. If the selector is placed in Low, the low-reverse band is applied, which then makes engine braking under deceleration possible.
Row three displays the Rear Clutch assembly. The shift lever is moved to get the car in motion and then left alone until the car is stopped. Also: -- check the shiny chrome part of it that plugs into the front of the transmission. Street and weekend-racing C4s can easily handle 250 to 600 hp without breaking a sweat. One thing you want to be prepared for is small changes that happened in C4 production, such as low-reverse clutch-return spring design. Power stops at the front-unit ring gear. The output shaft has four sets of splines cut into it.
The governor support bolts to the case and it has three purposes. For 1970 only, there was a larger. There are four or five clutch frictions in a stock C4 V-8 forward clutch. It presents dipstick tube clearance problems in subcompacts, compacts, and intermediates. Step-2: Inspect Sealing Rings Critical Inspection Pump stator support sealing rings and contact surfaces should be closely examined for wear, scoring, and proper fit.
