What causes no reverse on a 4R44E transmission?
What causes no reverse on a 4R44E transmission?
Loss of certain gears can occur due to issues in at least two other circuits. Loss of solenoid oil due to end plug leakage can cause no Reverse, and loss or 3rd or 4th and can be repaired with 37947-13K.
When did the Ford 4R44E become a 5 speed?
The 4R44E was released in 1995 in the 2.3L and 3.0L Ford/Mazda rear-wheel-drive units. In 1996, with the 4.0L, the drive components were beefed up to become the 4R55E. In 1997 the unit became a 5-speed by applying the front servo to obtain an overdriven first and 5th.
How do you replace an OE forward modulator valve?
Replace OE Forward Modulator Valve By positioning the manual valve furthest into the bore, air pressure can be used to blow the modulator valve out. If there is any visible wear or ridge in the bore, buff this area with Scotch-Brite™ placed on a twisted wire and inserted into drill. Install the PTFE seal onto the Sonnax valve.

What’s the difference between 4R44 and 4R55E transmission?
About This Transmission: 4R44E / 4R55E – The name 4R44E means 4 forward gears, rear-drive platform (or 4WD, with a different tailshaft housing), rated for 440 ft/lb torque (after torque converter multiplication) and electronic shifting. 4R55E is the same but heavier duty and rated for 550 ft·lbs.
What causes no reverse on a Ford 4R55E?
Either the bore in which the intermediate servo pin rides in is worn out, or the spring on the intermediate servo piston is too strong. 6) No reverse: If the transmission has no reverse you most likely have a bad SSA solenoid. 7) Delay going into reverse of a forward gear: Has the valve body been removed recently for any reason?
The 4R44E was released in 1995 in the 2.3L and 3.0L Ford/Mazda rear-wheel-drive units. In 1996, with the 4.0L, the drive components were beefed up to become the 4R55E. In 1997 the unit became a 5-speed by applying the front servo to obtain an overdriven first and 5th.
What causes a harsh shift on a 4R44E?
From the same circuit the complaint can be delayed reverse, flare 1-2 or 2-3, and harsh shifts following a forced downshift. The harsh shifts occur because the EPC “booster” valve gets stuck at maximum flow. EPC circuit problems also cause broken bands and servo piston seal blowout.
Can a TCC regulator be replaced on a 4R44E?
If line rise is poor because of a dirty EPC solenoid or leakage within that circuit, then feed to the TCC regulator valve will be poor (the solenoid can be replaced with [56842B-01]). The EPC circuit wears and leaks at multiple locations, but it also has an EPC and engagement control valve that sticks (and can be replaced with ( 37947-11K ).
Is the 4R44 the same as the 5R55?
Since 1995 there have been many valve body, plate or solenoid changes. Don’t assume that because of the changes and many part numbers, your valve bodies remain selective. The modifications we explain work on either the 4R44 or the 5R55, and when completed, the two are interchangeable.
Loss of certain gears can occur due to issues in at least two other circuits. Loss of solenoid oil due to end plug leakage can cause no Reverse, and loss or 3rd or 4th and can be repaired with 37947-13K.
What kind of transmission does the Ford Ranger have?
The two major versions of this new transmission were the 4R44E and 4R55E. The transmissions are fundamentally similar in design, varying only in the durability of key components based on the type of duty they were to be used for. The 4R44E was used in lighter-duty applications, namely with 4-cylinder or 3.0 L V6 models of the Ford Ranger pickup.
How many gears does a Ford 4R44E have?
The name 4R44E means 4 forward gears, rear-drive platform (or 4WD, with a different tailshaft housing), rated for 440 ft/lb torque (after torque converter multiplication) and electronic shifting. 4R55E is the same but heavier duty and rated for 550 ft·lbs.
When was the 4R55E replaced by the 5R44E?
The 4R55E was short-lived however as it was replaced in all instances where it was used with the newer 5R55E during the 1997 model year. The 4R44E continued on through the end of the 1990’s before being replaced by the 5R44E (5R55E’s relative).
What causes a clutch leak on a 4R44E?
Leakage at the coast clutch valve can result in loss of 4th, 5th, or engine braking (you can eliminate leakage with 37947-33K ). When you examine this valve body (see Figure 2 ), you see the many “L” retainers.
Why is my transmission not shifting to third gear?
If you ignore the signs for too long, it could lead to a possible failure of the transmission. Let’s see what could be the reasons for the auto gearbox not to shift from second gear to the third. Overheating could be a reason for the gear to stick and the low fluid level is the culprit for making the transmission overheated.
What kind of problem does a 1997 Ford Ranger have?
The contact owns a 1997 Ford Ranger. The contact stated that one minute after starting, the vehicle failed to shift into gear and the vehicle stalled. The vehicle was not taken to the dealer, however the manufacturer was notified.
What kind of transmission does a Ford Ranger have?
I drive the 2003 Ford Ranger edge v-6, 3. 0. In stop and go traffic my transmission shifts very hard into 2nd and 3rd gear. . . It has happened numerous times through out the year I’ve had the truck. The problem is usually from 0-25 mph.
Why was the gear shift cable melted on my 1996 Ford Ranger?
The gear shift cable was melted because of its proximity to the exhaust system, according to the repair shop. I have the part which clearly shows heat caused the failure. I called Ford customer service and my dealer service department. I was told it was a “freak” occurance and not to worry ablut it. See all problems of the 1996 Ford Ranger .
Why is my transmission not working on my Ford Ranger?
When trying to pass other cars or when going into passing gear transmission goes into netural, you have to take foot of gas padel and step on gas pedal and the truck goes back into gear. Transmission has been replaced and dealer will not make any more repairs.
Is the 4L60-E transmission a teardown or rebuild?
This is a video of a 4L60-E Transmission complete disassemble and rebuild. You will recognize the first half of the teardown, the rest I had misplaced it but found it, so I put it all together as one video as I intended to do a long time ago. And yes, it’s an old video. Loading…
What kind of solenoid does a 4R55 have?
1) Solenoid failure: The 4R55 is an electronic transmission and as such, it contains a few solenoids. All solenoids are subject to failure. The two most likely to fail are the transmission pressure control solenoid and the torque converter solenoid. All of the solenoids can be easily checked with an ohm meter.
When did the 4R44E become the 5R55E?
In 1996, with the 4.0L, the drive components were beefed up to become the 4R55E. In 1997 the unit became a 5-speed by applying the front servo to obtain an overdriven first and 5th. From that time on, it’s become either a 5R44E or 5R55E. Since 1995 there have been many valve body, plate or solenoid changes.

Why is my coast clutch not working on my 4R44E?
The CCS is not modulated, but controlled as an on-and-off valve by the SSD/CCS solenoid. When this bore is worn, the solenoid oil flows around it, resulting in the loss of overdrive servo release pressure. This results in no 4th in a 4R or no 2nd and 5th in the 5R unit. If it sticks, the coast clutch will not apply.
If line rise is poor because of a dirty EPC solenoid or leakage within that circuit, then feed to the TCC regulator valve will be poor (the solenoid can be replaced with [56842B-01]). The EPC circuit wears and leaks at multiple locations, but it also has an EPC and engagement control valve that sticks (and can be replaced with ( 37947-11K ).
