The photo below shows the flexplate adapter attached to the torque converter and the components. Have you been able to determine how much the extra 4 quarts of fluid has lowered the normal operating temperature of the transmission? The best way to combat the heat is toYou want to invest in the biggest cooler that will fit your vehicle. We have managed to find and address several manufacturer failure points that have made our 5R55S transmission rebuild one of the best on the market. Here are a few things you can do to your Mustang 5R55S automatic transmission to make it stronger: Shift Improver Kit: These kits include parts that help increase the line pressure of the transmission. Ford manufactured this transmission between the years 1996 and 2011. This Transmission comes with a performance built 5R55S torque converter. 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.
After all, they are not designed to last forever. Virtually all production automatic transmission equipped vehicles utilize a cooler internal to the radiator. We have managed to find and address several manufacturer failure points that have made our 5R55S transmission rebuild one of the best on the market. Note to Explorer owners: the stock pan has slants at front and rear so that the stock pan can be dropped without hitting the frame cross member, exhaust pipes or catalytic converter. Also I found that all clutches and bands were toasted. This will help under extreme handling conditions and prevent the pan from being sucked dry. The specified stall speed limits in my Aviator shop manual are 2545-2988 rpm after testing all forward speeds and reverse.
You don't want racing clutches for towing. The drag racing articles on torque converters I've read indicate that acceleration from a stop increases when the stall speed is increased from stock allowing the engine to operate at higher torque engine speeds. It includes seals, gaskets, and Raybestos Powertrain clutches. The two unused bosses are shown on the left, bottom of the pan. He showed a tool in one of them don't know which one. A will include upgrades and modifications designed to make them last long. 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.
When I test drove my Sport before purchasing, at light throttle the shifts were so soft it was hard to determine when they occurred and how many forward speeds there were. Remember when the only way to fix a worn servo bore on our trusty Ford 5R55W, 5R55N, and 5R55S transmissions was to have them bored out and sleeved. Be sure to jump on this sale price while quantities last. Give us a call for discounts on towing and shipping and custom installations. The large ratio boost valve provides higher pressure incrementally and when it is needed the most.
Every unit has upgraded parts and goes through our meticulous testing system. They are typically hardened steel and machined to improve oil lubrication. Numerous aftermarket modified valve bodies and modification kits are available. There may be cheaper options available. Unfortunately, most of the kits available fail to list the included parts and I'm not familiar enough with the transmission to recognize them. Sonnax remanufactured valve bodies are backed by a Limited Lifetime Warranty. A Valve body repair or Update kit will usually correct these problems.
For every 20 degrees it goes over 200 degrees it cuts the life span of the transmission by a factor of two. The 5R55S is a 5-speed automatic transmission developed for Ford Lincoln and Mercury applications. The 5R55S transmission is now for sale at an unbelievably marked down price. Hiram Gutierrez did a video or several on that process. The 5R55S is a 5-speed automatic transmission developed for Ford Lincoln and Mercury applications.
What surprises me is that the Aviator engine with the same transmission has a slightly lower stall speed than the Explorer. I think my approach will be a modest increase in line pressure from a nonstandard fluid pump valve and a custom tune. If you are a top wrench, we will supply everything you need to perform the upgrade. A design flaw in my opinion of all the 5R55 transmissions and many others is the lack of a line pressure sensor. 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? Only the pan, dipstick and tube are included. I high recommend you consider replacing your worn out transmission with one that has been re-manufactured over one that is simply rebuilt. In fact, we can arrange to pick up your Ford, custom build your transmission, and have it back to you in just one to five days.
A stock 2004 Explorer pan is shown below. This will help under extreme handling conditions and prevent the pan from being sucked dry. This is a direct replacement for Mustang, Ranger, Mountaineer, Aviator and Explorer models. There are literally available for the engines found in these cars. Backed with solid TransLab Engineered improvements from Superior Transmission Parts, Inc. It can even be performed with the transmission still mounted in the vehicle.
