Also keep in mind that a re-manufactured transmission comes with a than a rebuilt transmission; three years compared to an average 90 days for a rebuilt transmission. Step-7: Use Grease For Pump Gasket Retention Apply a thin film of transmission lube for gasket retention prior to front pump installation. Make sure your valve body and transmission case match. This gives you a gear reduction of 2. After you replace the manual and kickdown shifter seals this is the end result.
I cannot overstress the importance of checking clutch clearances followed by an air-check on each. Step-5: Install Inner Race Next install the one-way roller clutch inner race. With the reversehigh and forward clutches applied, both input and output shafts are connected and the entire package rotates at the same speed for a 1. Fluid flow begins at the pump cavity and flows into the torque converter. The C6 remained in production long after it was dropped from Ford passenger cars and trucks because it remained popular with companies that needed it for heavy-equipment applications. Monitor seal status as the pump seats.
When you apply the reversehigh clutch, it engages the forward clutch. This turns the the ring gear, which is tied to the output shaft, at a ratio of 2. Inspect the pump cavity and gears for abnormal wear patterns and scoring. The main regulator valve is next, which regulates control pressure. These letter codes can be found cast into each apply lever. Because the reverse planet is held still, this causes the sun gear to be driven in the opposite direction as the input shaft. I always replace this bush and extension housing bush as they are often worn.
A will include modifications and upgrades designed to make the transmission stronger and last longer. This one gets five clutches. External Assembly Step-1: Inspect Throttle Valve The throttle valve, which is actuated by the vacuumoperated throttle valve assembly vacuum modulator. I am often inclined to suggest a new Belleville spring with every transmission build because this piece gets stressed to where cyclic fatigue takes its toll. Instead of a low-reverse drum as in the C4, you instead have a low-reverse clutch package tied to the case, which performs the same function in a C6. This transmission was designed and produced to be Ford-tough like no other automatic had been to date. The low-reverse clutch and hub, one-way roller clutch, and the output shaft are visible.
Step-10: Install Thrust Washers Numbers-3 and -4 thrusts are installed. In second gear, fluid under pressure energizes the intermediate servo, thereby locking the band, forward clutch drum, and sun gear. This kit comes with all needed soft parts to rebuild and modify your C6 for most any type of application. And this is where you are in first and second gear. And then fill the pump cavity with assembly lube for a good start-up. A new heavy duty boost valve is included with this shift kit. If endplay requires adjustment, there are a variety of thicknesses available.
Get cover and piston square with the case and gently press into place. Stick them in the grooveswith assembly lube to hold them in during assembly Front assembly together on the bench. Any scoring is unacceptable and must be machined out or replaced. Inspect pump gears and cavity to be satisfied with their condition. Step-14: Insert Torrington Thrust Number-7 Torrington thrust bearing is next. To reduce line pressure—adjustment is counterclockwise.
Geartrain Installation Step-1: Install Forward Geartrain The forward geartrain splines right in like this. Step-2: Lubricate Seals C6 build-up is in subassemblies beginning with the forward clutch shown here. The extra thick and wide construction reduces the chances of breaking during standard performance. Please note some prior transmission rebuilding experience and special tools is recommended. The reverse-high clutch rides on the pump stator. Step-7: Inspect Steels Critical Inspection Inspect low-reverse clutch steels for heat checking. With pressure applied, forward clutch looks like this right with clutches compressed and Belleville spring distorted.
Make sure you get a good factory manual. Through the Gears As the reverse-high clutch direct clutch and input shell come into play, power begins to flow. You could use a super-thin film of Form-Agasket non-hardening sealer on leakers but not everyone agrees with this approach. These are the same parts we use on all of our Street Smart and racing transmission packages. The governor has two valves that work hand in hand.
Step-2: Reassemble Governor Assembly After you reassemble the governor assembly it is ready for installation. Broader Performance goes to extreme detail with its blueprinted valve bodies, offering you everything from a stock auto-shift valve body, manual and reverse-pattern, to pro tree. You can use a clutch spring compressor shown or C-clamps for spring compression and snap-ring installation. We sell the top quality C6 transmission kits you need to for your performance or racing trans rebuild. In first gear, the input shaft turns the forward planet, which reverses input shaft rotation to the sun gear. Thickness determines clutch clearances though adjustment is determined by selective snap-ring thickness. Low drag equals better performance at the tailshaft.
Step-4: Install Governor First lubricate the governor distributor sealing rings then slide the assembly onto the output shaft. In other words, the R servo is a no-brainer because racers have been using it for decades with great success. Hold the adjustment stud and tighten the locknut 35 to 40 ft-lbs. Once the primary governor opens, allowing fluid pressure to pass, the secondary valve comes on line as a means of controlling the shift point based on vehicle speed. Read it over a few times to get familiar with the components. Never go on feel because overtightening means distortion and valve malfunction. With the throttle open at 10 inches of vacuum and the transmission in any forward gear, you should see 100 to 114 pounds of line pressure.
