Step-3: Install Pump O-Ring Lubricate and install the pumphousing O-ring seal, making sure seal is square with groove. Clutches and bands burn up from slippage and extremes of stress such as towing or racing. Step-5: Install Torque Converter If installed incorrectly, the torque converter can cause pump and converter damage. Although transmission assembly lube is used here, you can also use Vaseline for seal lubrication. After you replace the manual and kickdown shifter seals this is the end result. Step-9: Install Output Shaft Lubricate and install the output shaft, making sure it is firmly seated in the case.
Install the gear in the governor distributor sleeve. I got all the parts to Frank's specks and added the 300m input shaft and it's held up to my 472 doing lo range 4500 rpm launches on cut tires with a 300 shot of nitrous. Surface irregularities can also cause slippage and heat. These clutch frictions are splined into the low-reverse clutch hub. You can purchase an eBook just like you would any other book on our website. Various degrees of rebuild kits out there, from just gaskets, to gaskets, seals, bushings, plates. Both assemblies should be completely flush if properly seated.
I edited the text and added a pic to clarify the difference. It's best to have it able to rotate around for removing and installing components. You can use a clutch spring compressor shown or C-clamps for spring compression and snap-ring installation. The C6, unlike the C4, uses an intermediate servo apply lever to help provide mechanical advantage to apply the intermediate band. Step-3: Insert Belleville spring Forward clutch gets the Belleville clutch-piston return spring, also known as a disc spring. Piston seals are removed at this time.
Final Assembly Step-1: Assemble Pump Pull together the pump halves and torque the bolts to 28 to 40 ft-lbs. And, if missed a second or third time, failure is inevitable again unless you catch the problem this time. Step-4: Disassemble Front Pump Critical Inspection Next, disassemble the front pump and inspect for abnormal wear patterns. This is checked with the throttle valve removed using a vacuum pump or intake manifold vacuum from an operating engine at idle. This is something to be mindful of as you amass parts for your C6. You have to rent or borrow one. C6 Transmission Shift Better, Last Longer When it comes to transmissions, no other company provides this level of commitment to their clients.
There have been more than 260 variations of the T-5 produced over its production life. Here are the six known Ford servo-apply-lever ratios. The front band is presoaked in trans oil and fitted in next. Written by George Reid and Republished with Permission of CarTech Inc. The sun gear is splined into the lowreverse rear planet, which again reverses rotation to the output shaft. These steels have excessive scoring and should be replaced. It's an inexpensive and smart investment if you're considering this task.
It allows you to quickly remove and install drum seals, the most difficult part of most auto rebuilds. Every automatic transmission will need a universal clutch spring compressor as well as snap ring pliers and pic sets for removing valve guides. This is an extremely rugged transmission as it came from Ford. Cold transmission fluid gives you an erroneous pressure reading on the high side because the fluid is denser when cold. Transmission failure is normally a chain reaction—a series of small events and disruptions that ultimately lead to failure and a tow truck. Step-8: Inspect Forward Clutch Completed forward clutch looks like this at rest with no pressure applied left. I'm thinking you can dispense with the torque wrench for the big nut on the output shaft, otherwise a ft lb torque wrench would be nice.
In How to Rebuild and Modify Ford C4 and C6 Automatic Transmissions, author George Reid walks readers through the process step-by-step, from removing the transmission from the vehicle, to complete disassembly and cleaning, to careful reassembly, to proper re-installation and road testing. The gauge pressure range needs to be 0 to 400 psi. A pressure-relief valve prevents overpressure and catastrophic failure. A burned intermediate band is a sign of poor adjustment or inadequate servo pressure. You cant build a drag racing transmission for 500-600 hp as if it were in a stock build. This gives you a gear reduction of 2. When you install clutch pistons, do it gently and carefully to prevent seal damage, which is one of the leading causes of transmission failure.
They used some real cheez parts in some of thier trannies. Heat damage cannot be machined out of steels. I have done a few though, and I still wind up with problems now and then. . I was fortunate to turn my love of the automotive world into a hobby that led to an exciting career, with my past of working as a mechanic and as an accountant in the automotive world provides me with a unique perspective of the industry. 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. Bellhousing and main case are a one-piece design.
When this happens, the reverse-high clutch is applied to get the input shaft tied to the sun gear. Step-6: Remove C-Clip Remove the tailshaft C-clip next, which releases the tailshaft. The C6 differs in where the power travels at this point. Heat damage shows up as brown, black, or blue score marks. The large sealing section of the piston is too large and causes the piston to hang up in the bore. The C6 differs from the smaller C4 in its low-reverse function.
