Ford Expedition Transmission Problems & Solutions
By 1997, Americans were madly in love with the SUV, and Ford’s 2-door flagship Bronco just wasn’t going to cut it anymore. So the engineers in Dearborn took an F-150 chassis, and welded a 7-9 seat SUV body to it. The resulting Ford Expedition was an immediate hit, and it continues to be a strong seller, even on the used market. A recent study found that the Ford Expedition was 4th on a list of the top 10 vehicles still on the road with over 200,000 miles. Proving that Ford knows how to make a durable family vehicle. But no matter how tough it is, owners aren’t immune to Ford Expedition transmission problems.
Common Problems with the Ford 4R100 / 4R75E / 4R75W / 4R70W Transmission
Slipping and/or No Forward Gears
One of the more common Ford Expedition transmission problems is slipping, and/or no forward gear engagement. This is usually caused by a cracked forward clutch drum, which is the result of a design flaw in the snap ring and piston. When fluid pressure is applied to engage the clutch, the drum itself can crack, and you won’t be going anywhere. To keep this from happening, every remanufactured Ford Expedition transmission from Street Smart Transmission gets an upgraded snap ring, and upgraded 1-2 and 2-3 accumulator pistons to extend the service life of the 4R70W / 4R75W forward clutch drum. In addition, a stronger spiral-lock snap ring and staked retainer are also used for the intermediate clutch. Plus, 2001 and newer models receive a new 3-4 capacity valve sleeve, with an extra-thick zinc-coated Super Tough Plate to eliminate plate cracking and cross leaks caused by repeated stress from the 2-3 accumulator piston spring retainer.
Delayed or Failed Shifts
In order for an electronically controlled Ford 4R7 transmission to shift gears, the computer has to send an electric charge through a coil of wire that’s wrapped around little plunger mechanisms that are situated throughout the valve body. Called solenoids, these vital components direct pressurized ATF to actuate the gear changes. If one of them wears out, or fails due to heat or excessive vibration, your Ford Expedition transmission will exhibit delayed shifts, or a complete failure to shift. That’s why each remanufactured Ford Expedition transmission receives the more durable upgrade EPC solenoids and solenoid clips.
One of the most common Ford Expedition transmission problems is overheating. As your transmission shifts up and down, all of the moving parts generate friction, which results in heat. Towing, and driving in the mountains or traffic causes the transmission to shift a lot, increasing the heat buildup. If the transmission fluid can’t be properly cooled, the transmission itself will overheat, just like an engine. When this happens, key components like the transmission bands, clutches, seals, valve body and bearings will become severely damaged. So to avoid premature transmission failure, we encourage every remanufactured Ford Expedition transmission customer to have an auxiliary transmission cooler installed.
How to Solve Ford Expedition Transmission Problems
Solution A: Buy a Used Ford Expedition 4R100 / 4R75E / 4R75W / 4R70W Transmission
The quickest way to solve most Ford Expedition transmission problems is to pop into your local salvage yard and pickup a used 4R100 transmission / used 4R75 transmission / used 4R70 transmission. These are generally pulled from a wrecked, abandoned, or non-running Ford Expedition, and sold with a 30-day replacement warranty. However, there’s no way to verify the condition of the internal components, so you could windup with the same problems, or worse. And that junkyard warranty doesn’t cover labor charges. So you’ll be paying an installation charge twice if something goes wrong with the first used Ford Expedition transmission.
Solution B: Buy a Rebuilt Ford Expedition 4R100 / 4R75E / 4R75W / 4R70W Transmission
A safer alternative would be a rebuilt 4R100 transmission / rebuilt 4R75 transmission / rebuilt 4R70 transmission. These are typically built by a mechanic using a factory OE master rebuild kit, and given a 1-2 year warranty. However, the functionality and long term durability of your rebuilt Ford Expedition transmission depends on the skill of the technician building it. You’re also not going to get all of the upgrades that Street Smart Transmission provides, which further impacts its long term durability.
Solution C: Buy a Remanufactured Ford Expedition 4R100 / 4R75E / 4R75W / 4R70W Transmission
Since your big Ford can go for at least a quarter-million miles (with proper maintenance), the best solution would be a remanufactured 4R100 transmission / remanufactured 4R75 transmission / remanufactured 4R70 transmission from Street Smart Transmission. These are built in a factory, and have to undergo strict quality inspections throughout the build. Once completed, each remanufactured transmission is placed on a special dyno machine where it’s subjected to a series of hot and cold tests that are designed to simulate real-world driving. This enables our technicians to fine tune the shift points, and catch any problems before the transmission is shipped to you. All of this allows for a plug-and-play installation, and eliminates the often trouble-prone break in period for all of the new components. In addition, all customers receive a transferable nationwide 3-Year/Unlimited Mile Warranty that will pay for parts and labor at any licensed repair shop in the country. So you’ll get a transmission that exceeds OE specifications, and a warranty that protects you no matter where you go. To learn more, give us a call at 1-866-812-7560.
