What to do about a worn servo bore on a Ford Explorer?
MOST COMMON FORD EXPLORER TRANSMISSION PROBLEM (WORN BORES)! [U.S. Patent No. 9,121,418] Up until our kit was available, the only available fix for a worn servo bore on the Ford 5R55W, 5R55N, and the 5R55S transmissions was to have the bores bored out and sleeved. This obviously involves dropping the transmission.
What kind of bore does a Ford servo have?
The shafts for the servos are hardened (very hard!) steel going through a machined aluminum bore in the transmission case (brilliant design!). This gives you a situation of a very hard metal, rubbing against softer aluminum, so the aluminum wears. Not only that the OEM machining has sharp edges that scrape away at the bore.
What should I do if my servo bore is not working?
A band adjustment should be done to make sure they are not broken and also that there is enough adjustment left and not work too badly. It also helps in the installation if our kit is installed. You should pay very close attention to how it shifts and know what gears it is having problems with.

What causes no up shifting on a Ford Ranger?
4) No up shifting: This problem can be caused by the solenoid regulator valve being out of position. 5) Slips on the 2 – 3 shift: There are two different issues that can cause this problem.
What causes no 2nd gear on Ford 4R55E?
A low reading means that there is most likely a short in the internal wiring and no reading means the wire is broken. In either case, the solenoid will need to be replaced with a new one. 2) No 2nd or 4th gear: This is often caused by the solenoid regulator valve being out of position.
How many gears does a Ford Ranger have?
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.
