The additional cost may be higher than installing a reman or rebuilt transmission--not to mention the extra downtime. Bring a bunch of extensions and maybe a wobble for your ratchet so you can get the wrench back far enough to work. Step-2: Inspect Reverse-High Clutches Critical Inspection Inspect reverse-high clutches for wear and evidence of slippage and burning. When it becomes brittle it loses its elasticity and can no longer hold fluid back. The torque converter is unlocking.
Inspect gear, pawl, and thrust washer for damage and wear. Instead of a low-reverse clutch drum and band, you have a low-reverse clutch tied to the case. Jack Jack stands Start the engine of your 1993 Mercury Cougar and allow it to run for 10 minutes to circulate and warm the engine fluids. Any resistance to rotation binding is reason for discard or rebuild. Ford is infamous for annoying engineering changes, dozens of them over the production life of a unit design, which means you must pay very close attention to parts intended to work together and parts that were never intended to be together. Here is a quick step by step guide for removing your 4R70W transmission from your Ford F150 pickup truck two wheel drive version only.
A 3-speed automatic Although transmissions are complicated vehicle components, certain fixes and troubleshooting measures can be easily done by the common owner for a 1993 Nissan Altima. Remove the inspection plate from the front of the transmission case. Step-7: Remove Governor Support Remove the governor support assembly, along with two pressed-in hydraulic lines. Step-15: Note Any Clutch Wear Clutch wear is a strong indicator of transmission health. 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.
Step-6: Inspect Governor Critical Inspection Governor assembly has two points of inspection: primary and secondary control-valve pistons for freedom of movement and spring integrity. You wont need anything special. Transmission shops have special spring compressors for clutch disassembly; however, you can do this at home with four C-clamps. This trans is pretty darn heavy too if you're dropping it without the use of a trans jack. Inspect the piston for damage and a worn seal. Thanks for your input guys.
The F-150 became the smallest full-sized truck in the F-Series lineup from Ford, with the F-250, F-350 and F-450 having larger bodies and bigger engines. For those that have either had a complete failure of the transmission or its simply time for an upgrade, we also offer complete transmission packages in various levels depending on the horsepower and use of the truck. Every transmission is cold and hot tested before shipment. However, transmissions need the same kind of attention engines do. Plan to replace all thrust washers and bushings.
Step-4: Disassemble Front Pump Critical Inspection Next, disassemble the front pump and inspect for abnormal wear patterns. Take note of bolt locations. Scoring adversely affects pump pressure. Each had a unique array of transmissions best suited for the model's design. One person starts the engine, while the other holds the line over the drain bucket.
Take lots of pictures and notes as you go along. Sometimes it does not come out with the filter. They can be reused if no real wear is found. Automatic transmissions are very heavy parts and great care should be taken when removing them from the truck. Note that Ford does not recommend ever changing the filter. Step-11: Note Parking Pawl Parking pawl and gear on the C6 is similar to those in the C4—quite visible when the governor support is removed. Piston should pop right out.
But be prepared; most are gone and you may need to replace yours. Do a complete inspection, checking planet gears for excess wear and oscillation. Step-14: Remove Clutch Pistons Use compressed air to remove clutch pistons. This is a pretty old thread so none of the guys that posted above are very active any more. It was also found in the pickup truck. Whether it is the mass rebuilder or an independent shop, plenty gets overlooked in the course of a transmission teardown and rebuild, which leads to the same kind of failure again and again.
Once on the ground, slide the transmission out and away from the bottom of your truck. The transmission revs high in all the forward gears. This transmission can be found in the 2005 Navigator, 2006 Explorer and Mountaineer, 2007 Expedition, 2008 F150 and 2010 Mustang. The same can be said for a C6 with a screw-in throttle valve from 1966 to 1971, and then press-in from 1972-on. Step-3: Disassemble Forward Clutch Next, disassemble the forward clutch by removing perimeter snap-ring, clutches, and drive plates.
The problem is most likely that the torque converter clutch is not engaging. Remove all electrical and mechanical connections, including the shifter linkage, transmission lines, the electronic harness and any vacuum lines. Mass rebuilders, for example, toss parts in bins during the rebuild process with reckless abandon, clean them up, machine, or replace as necessary, and put transmissions together haphazardly. As soon as you see air shut off the engine. Step-8: Remove Tailshaft C-Clip The tailshaft is secured with a C-clip. They should also be removed and replaced.
