Outer seal goes on the piston and inner seal goes inside the clutch drum. You get better load distribution and torque multiplication through Simpson planetaries and a ring gear around a sun gear. To aid in shift quality and long term durability, it was the first automatic transmission designed to use the Borg-Warner flexible shift band. A re-manufactured transmission will also include a ; three years compared to an average 90 days for a rebuilt transmission. I always replace this bush and extension housing bush as they are often worn.
Among the aftermarket improvements were a high-performance shift-kit and power valve, and heavy-duty clutch. I had one but it turned out to be unsueable due to erosion so I sold it to a welder on Ebay. It had weak seals that allowed moisture inside the case, and occasionally the gears inexplicably shifted into neutral while the vehicle was in motion. If the output shaft is hard to turn, check sealing rings, contact surfaces, and governor sleeve for any irregularities. Your hub for horsepower Get first access to hit shows like Roadkill and Dirt Every Day Join free for 14 days now Confident that there was a lockup converter that would do the job, the next step was to figure out which transmission to couple it to. But you must be careful to properly match servo covers, pistons, and apply levers. Prompt engine fluid checkups are highly possible with the use of an efficient oil analyzer, which enables mechanics to easily assess and determine whatever engine problems need fixing.
When it becomes brittle it loses its elasticity and can no longer hold fluid back. Your problem could be pretty simple. Note where machined to use that bearing there is a shoulder left on the outer edge of the race to keep bearing in place. Pressure Relief Valves Hydraulic pressure is there for control and lubrication purposes in the C6. Step-6: Install Hub Install the low-reverse clutch hub, making sure roller clutch fits neatly and smoothly around the inner race. Step-10: Install Bearing This Torrington thrust bearing is next. These purely mechanical no electronic controls automatic transmissions are still popular with racers, hot rodders, and restorers today due to their simplicity and low cost.
C4 Gear Ratios First Gear 2. For the first-year the C6 was a standalone unit, meaning the valve body was Dual-Range for that year only. But, they lack the overdriven gears and lockup torque converters the newer transmissions rely upon to boost fuel economy figures. Frank lists the Ford part number below. As power flows to the sun gear, it travels to the low-reverse or rear planet carrier to the low-reverse ring gear, which is splined to the output shaft.
Inspect the pump cavity and gears for abnormal wear patterns and scoring. However, C5 cases and many internal components are similar or identical to the C4, and are quite suitable for performance applications thanks to their improvements, as discussed in Chapter 4. At low vacuum, expect to see 154 to 180 pounds of line pressure in any forward gear. The governor has two valves that work hand in hand. When the transmission is in first or second gear, the forward planet is always in motion.
Step-16: Install Valve Body With close attention to manual shift and kickdown levers, install the valve body. The front band is presoaked in trans oil and fitted in next. The C6, unlike the C4, uses an intermediate servo apply lever to help provide mechanical advantage to apply the intermediate band. You have no winter, and hardly any rain. The K right is 1. The C6 was included in the following engines: 300, 302, 351w, 400, 351c, 351m, 460, 6. The low-reverse clutch and hub, one-way roller clutch, and the output shaft are visible.
On the left is a C6 forward clutch hub. Also Check the wires going to tranny and make sure they are not corroded. Ford also matched the 4R100 with larger diesel-powered engines. Step-6: Install Washer Lube and install the number-10 thrust washer. Governor Installation Step-1: Inspect Governor Assembly Disassemble and inspect the governor assembly.
Although transmission assembly lube is used here, you can also use Vaseline for seal lubrication. This is a critical safety item; so pay very close attention to detail here. A lockout button disables Overdrive operation allowing the transmission to shift through the first three gears only. Step-2: Reassemble Governor Assembly After you reassemble the governor assembly it is ready for installation. Prior to 1972, a screw-in throttle valve and gasket is used.
On Advice from Frank Merkl the groove is machined. I would first remove both of them and clean them up with an electronic specific cleaner. Monitor seal status as the pump seats. Use a center punch for alignment. Fluid flow begins at the pump cavity and flows into the torque converter. Step-17: Check Valve Body Function Although the governor has already been installed, here is how to check valve body function through the governor passage at the tailshaft.
These clutch frictions are splined into the low-reverse clutch hub. Hold the adjustment stud and tighten the locknut 35 to 40 ft-lbs. Cores can be purchased and rebuilt to suit the needs of a specific vehicle for much less than a comparably rebuilt modern overdrive automatic transmission with electronic controls. This means the C6 is equipped with one band and servo instead of two. C6 is shorter so driveshafts change lengths.
