How to adjust bands on 4R44E transmission?
Tighten the band adjusting stop using Band Adjustment Torque Wrench Set T71P-77370-A. The wrench will click at 14 Nm (10 lb-ft). Back off the band adjusting stop exactly two turns and hold that position. Tighten the locknut to 47-61 Nm (35-45 lb-ft) using a 19mm wrench.
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.
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.
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).
Why are the plugs on my 4R44E not working?
In newer versions, plugs are anodized and cannot be altered. As these toggle, they wear the casting and not the plug. Besides the plug and retainer issues, bore wear, as illustrated in the product announcements in this catalog and indicated by the arrows in Figure 4, add to the complaints.
What’s the difference between the Ford 4R44 and 4R55E?
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.

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.
