Master Rebuild kit with friction and steel plates, 2. This allows full pressure to the overdrive servo and band. If the spring is missing and cannot be found, replace the seal. Use a bushing driver of the correct size and a press. Do a leak check with compressed air.
This allows for proper seating and prevents warping. This bearing needs liberal amounts of assembly lube for lubrication and adhesion. Transmission problems are often perceived as mechanical or hydraulic when they are actually electrical issues that adversely affect the hydromechanical parts. There are two bands, two one-way clutches, and four friction clutches used to lock and drive the gearsets. Working on this baby takes a level of study and experience most professionals get on the job. This Tech Tip is From the Full Book,. Covers transmission assembly, dis-assembly, diagnosis, and troubleshooting.
Bishop I definitely recommend a look at these transmissions, you've got to have a look. The needle bearing, also known as a Torrington bearing, reduces internal rolling and thrust friction. Torque the bolts gently in one-third increments, from the inside out. Step 8: Replace Shaft Seal and Install Manual Shift Linkage Always replace the manual shift shaft seal while you have the transmission apart. To improve shift quality, Ford eliminated the split-torque function in third and fourth gears.
Check the pressure plate for freedom of movement in the clutch drum. Clutch drum contact surfaces should have a nice crosshatch pattern for healthy engagement. Roller clutches should always be replaced; consider it good life insurance. The 2-3 back-out valve, as the name implies, regulates the feel of a 2-3 upshift. Work the sun gear drive shell back and forth to seat.
Master kit with friction and steel plates, 2. Solenoid operation and control are also different between 6F35 Generation 1 and 2. Step 2: Install Low-Reverse Servo Piston Cover Install the low-reverse servo cover and snap ring. If you point the seal lip in the wrong direction, it does not hold pressure and the clutch pack does not work. Reverse Gear and Neutral The reverse clutch is applied, connecting the input shaft to the reverse sun gear. Spring pressure here determines shift firmness. The transmission system is also capable of Tow Haul Mode which will provide all six speeds at higher shift points and also has manual shift capability.
This shaft operates inside the outer stub shaft. Step 6: Install Clutch Piston Special Tool Use a seal protection tool to install the intermediate clutch piston installation. Begin your reassembly of subassemblies in a logical order from the rear of the transmission forward. Step 5: Install Anti-Clunk Spring The anti-clunk spring arrow , which prevents the center support from moving and clunking, acts as a shock absorber for the center support. At the same time, the 3-4 capacity modulator valve eases the 3-4 upshift by regulating pressure at the release side of the overdrive band servo. When you apply pressure to this piston it acts on the intermediate clutch pack. Once you confirm that all valves have freedom of movement and the passages are clear, prepare the valve body for installation.
The lap joint must meet head-on and be perfectly aligned. The harness protects the wiring. Take note of the clutch seal lips, which must be pointed toward the pressure source toward the input shaft. Work the sun gear drive shell back and forth to seat. Like the other Deluxe Super Kits, it is the recommended starting point for a thorough transmission overhaul.
Step 8: Install Forward Sun Gear Drive Shell Stub Shaft This is the forward sun gear stub shaft splined into the planet carrier with the number-5 needle bearing installed. Valve bodies between 6F35 Generation 1 and 2 are also different which indicates the two are not interchangeable. Step 16: Compare Main Case and Pump Passages There is only one way to install the front pump. Be very careful not to scratch the clutch piston. Take note of how the rollers fit into the cage. Use plenty of lubrication as a pre-lube and for adhesion.
The 6F35 has two design levels, Generation 1 built from 2009 to 2012 and Generation 2 built from 2013 to present. Step 13: Install Forward Clutch Hub The forward clutch hub splines onto the outer forward sun shell stub shaft. Double-check the security of the band at the servo and anchor pins. Shifting Problems Be sure to think about when the malfunction occurs Does it occur during upshift, downshift, coasting, or engagement? The next items to check are the number-3 and number-4 sealing rings. Before mating them, make sure all contact surfaces are clean. The other four thickness options are green. Give these rings and grooves abundant lubrication.
First Gear in Drive In first gear, the forward clutch is applied, which ties the primary input shaft to the forward sun gear. Step 6: Install Center Support Retaining Ring Install the center support retaining ring and check the security of the center support. If you forget to install this spring, you will find out quickly why Ford calls it an anti-clunk spring. The planetary one-way clutch overruns. Step 3: Lubricate Seals Important! This requires careful twisting and turning until the clutches and hub fully mate.
