Click for enlarged view 3. Third is that the bushings in the transmission are worn and causing leakage in the converter ckt. Rapid wear of rings and cylinder walls, which can be caused by buildup in the grooves behind piston rings. The torque converter is unlocking. . Either problem is going to require that the transmission be replaced.

Click for enlarged view Up until 1998 all of the pumps could be interchanged, either as a complete set or as separate components. The Ford Expedition received the transmission for the 1997 and 1998 model years. In 1994, Ford introduced the 4R70W transmission, which uses the same shifter pattern, making it ineffective to examine the shifter to determine which transmission the vehicle has. The level 4 Enforcer comes with front and rear six pinion steel planet gears. The taillights n some tranny wires are ran on the same circuit. Transmission shifts hard into second and only after the rpms have gone very high. It had weak seals that allowed moisture inside the case, and occasionally the gears inexplicably shifted into neutral while the vehicle was in motion.

Now with a 1995 up type pump and a carbon fiber band. There were some casting changes that are most noticeable around the torque converter clutch valve figure and. When it becomes brittle it loses its elasticity and can no longer hold fluid back. Aftermarket 4R100 versions solved the problem by increasing its torque capacity to 1,000 foot-pounds. This may show up without heavy use. The rotor's outside diameter was increased from 3.

The later unit known as a 4R100 was produced in 1998 and was phased out by Ford by 2003. The torque converter clutch valve train has a bushing with a valve inside of it. Also Check the wires going to tranny and make sure they are not corroded. In this article we'll go over interchange, design changes, and compatibility between the pumps for these two units. In this case the converter will need to be replaced.

However, it did have some reliability issues. Another cause could be a defective line modulator valve, but this would most likely cause a problem in all the other gears, too. Ford also matched the 4R100 with larger diesel-powered engines. Ford reserved the 4R100 for its performance trucks and heavy-duty sport utility vehicles. It may feel like lock up is working fine.

For an alternate way to determine a truck's transmission, measure the transmission fluid pan. The stator support shaft was redesigned to accept the stamped steel coast clutch drum.

The problem here is the intermediate clutch pack is starting to fail. Click for enlarged view 2. The way to identify non-pulse width modulated is: 1. This increased the volume of fluid to help with delayed reverse engagement problems, especially when hot; and, like the 1991 changes, reduced converter slip problems. The identifying the factors to look for would be: A tag with code numbers on it and speed sensor location. 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.

Bushing or bearing contact surface area varies on the stator support shaft; depending on whether the coast clutch drum is cast or stamped. The stator support shaft can still accept the cast-iron coast clutch drum. This will save them money and make them a long term customer. Click for enlarged view The changes that took place in 1991 were in the converter charge pressure exhaust orifice, which increased by 0. The converter charge pressure exhaust orifice was eliminated; however, the area where the orifice would be installed still has stake marks, so don't be deceived figure 18.

Cause: Ford tried to use a mechanical diode for the intermediate Sprague this year and it dident work so well. Cause: When engine stalls when put into forward and reverse gears, may be hot or cold, or all the time the likely problem is that the lock up solenoid is mechanically stuck. The E40D pan measures approximately 20 inches in overall length, whereas the 4R70W transmission has a length of about 15 inches. Click for enlarged view 6. All of this adds up to as much as 47% more clutch apply area.
