Gear ratio error codes are very common on these transmissions due to servo pin bore wear occurring at a very low mileage, in some cases. The brass sleeve has proven to be more durable then the aluminum case, giving you more stability. Although the 5R55N is very similar to the W or S models, only a few parts are interchangeable. The o-rings redirect all the flow to the top of the piston where it is needed. We have the answer for your transmission.
The 2003 Thunderbird switched to the 5R55S and featured the option of Ford's SelectShift, which allowed drivers to mimic shifting like a manual transmission without a clutch. When it comes to price and quality you can be assured that this is a deal that is hard to beat. This Transmission comes with a performance built 5R55S torque converter. Combine this kit with our valvebody kit or upgrade. In this case, the high duty cycle of use wears down the bore reducing clutch and servo pressures. Is the dipstick calibrated marked for the correct fluid level or do you need to mark it yourself once you have determined the pan is full of fluid? Features increased lubrication flow and strength with a resized diameter that provides optimum stress distribution along the entire length of shaft and along the extended high gear splines to the oil ring.
The 5R55S, minus the SelectShift feature, was used in models of the Ford Mustang from 2005 until 2010. Also available our Super front pump assy. This is a direct replacement for Mustang, Ranger, Mountaineer, Aviator and Explorer models. We will let you know if we do. Used transmissions, since there is no way to know how many miles are on them, may fail at any time. The o-ring below the cross bore seals the loss of fluid to the reservoir. We finally broke through with our patent pending Sure-Cool Full Time Cooler Flow Valve along with enhanced Lube system that nearly Triples the Flow through the cooler and parts, especially the O.
These are just a couple of most common problems seen on these transmissions, but not all these problems may have this problem. The 5R55S is a 5-speed automatic transmission developed for Ford Lincoln and Mercury applications. O-ring grooves were machined into them and viton o-rings installed and a patented assembly sleeve make it complete. Warranties for a used transmission is only 30 days, 60 days, 90 days or 6 months. R emanufactured transmissions carry a longer, 3 year, nationwide warranty with additional upgrades while a rebuilt unit generally carries up to a 1 or 2 year warranty and upgrades vary from shop to shop. We receive numerous calls about these where someone has rebuilt the transmission, yet still experiences the same symptoms. The most common problem we see on these units is the excess wear on the case or valve body.
Also I found that all clutches and bands were toasted. Because after only 8 months and 25K Mile, the transmission quit on me again this time I lost the auto function + reverse with only P1700 code, and when I dropped the transmission for a complete inspection, I found that I have damaged overdrive ring gear bearing and overdrive one way clutches rotate free-wheal in both direction. But you can do that as many times as necessary. Every unit has upgraded parts and goes through our meticulous testing system. The 5R55W appeared in models of the Ford Explorer and Ford Ranger from 11. What kind of warranty coverage are you looking for? You can have a gear ratio error code without having an electrical code solenoid , but it is unlikely that you will have an electrical circuit code without a gear ratio error code. Was this review helpful to you? The 5R55E, though mechanically similar to the 4-speed 4R55E, was a new breed of electronically controlled automatic transmission with an additional forward gear.
The 5R55S transmission is now for sale at an unbelievably marked down price. Have you been able to determine how much the extra 4 quarts of fluid has lowered the normal operating temperature of the transmission? All variants are fundamentally similar to each other in design but differ in things such as specialized controls, gear ratios, or other elements based on the needs of the specific application the transmission is intended for. The o-ring above the cross bore seals the bore against loss and back pressure to the backside of the piston. Buying a used 5R55E or 5R55E transmission may save you money. The top of the bore is mostly concentric with the pin and the bottom is where most of the wear takes place, causing an ob-round shape. We had to build this transmission from the ground up to ensure it could fulfill the performance needs of its various applications.
The overdrive servo bore will usually have more wear due to it being used for second and fifth gear. This requires the pin to seal in the servo pin bore, as well as the release oil that both servos require. The loss to the reservoir causes loss in pressure to the top of the piston and the loss to the underside of the piston causes back pressure. Transmission case premature wear occurs on the overdrive and intermediate servo bores. This is a direct replacement for Mustang, Ranger, Mountaineer, Aviator and Explorer models. In 2003 the Thunderbird and Lincolns switched to the 5R55S that had the Select Shift allows drivers to shift like a standard without the clutch.
. Over time, the number of apply and release wears out and the pin can no longer seal properly. If you are a top wrench, we will supply everything you need to perform the upgrade. There are vehicles out there that have had this fix working in them for over 80,000 miles! A valve body repair or update kit will usually correct these problems. The 5R55E featured more precise computer controls necessary to accommodate the additional forward gear and introduced with a sophisticated friction-to-friction shift ability.
