4R75E / 4R70W / 4R75W Applications and Compatibility:

Newer transmissions that are referred to as 4R75E or 4R75W have modifications that compliment Fords switching to throttle by wire. The PCM was given a more powerful microprocessor and Ford added a turbine speed sensor to the transmission. This allows the PCM to know the speed of the input shaft after the torque converter which is used in combination with crankshaft speed to detect the amount of slipping going on in the torque converter.

4R70W indicates 4 gears, Rear wheel drive and Wider gear ratio compared to the AODE. In 2003 Ford revised the 4R70W transmission with a stronger ring gear that had 24 lugs, as opposed to 6, for the output shaft sensor (OSS) to read off of, a new torque converter, a revised front pump assembly, and a vehicle speed sensor (VSS) that compliments the OSS to improve shift quality and efficiency. These improvements allowed the 4R75W to handle more power while being more efficient and economical. While not used on all 2003 model year vehicles, the 4R75W/E transmissions eventually replaced the 4R70W/E.

4R75E / 4R75W Technical Service Bulletins

TSB 10-23-7 – Transmission Cooler Leak
2008 – 2011 Ford Crown Victoria – 2008 – 2011 Mercury Grand Marquis – 2008 – 2011 Lincoln Town Car
Problem – It’s not uncommon for a transmission fluid leak to develop on the driver’s side transmission cooler tube
Solution – Replace transmission cooler core

TSB 13-4-23 – 4R75E Transmission – Grinding/Slipping/Loss of Reverse
2008 – 2011 Ford Crown Victoria – 2008 – 2010 Ford F-150 – 2008 – 2010 Ford E-Series – 2008 – 2011 Lincoln Town Car – 2008 Lincoln Mark LT – 2008 – 2011 Mercury Grand Marquis
Problem – Some vehicles may experience a grinding/whining noise, unusual vibrations, slipping, and potentially a loss of reverse gear, all resulting from a failure of the planetary gear assembly

Common 4R75E / 4R75W Diagnostic Trouble Codes

Common Problems with the 4R75E / 4R75W

Slipping, Erratic Shifting, Harsh Forward or Reverse Gear Engagement: Some of the most common 4R75E / 4R75W transmission problems are slipping between gears, erratic up or down shifts, or a hard slam when the 4R75E / 4R75W transmission engages Drive or Reverse. There are a number of design flaws in this transmission, and any one of them could be causing these symptoms.

Another common problem is overheating. This happens when the moving parts inside the transmission are creating more friction heat than the ATF can remove. The most common cause of this condition is towing heavy loads, driving in stop/go traffic, or on mountain roads where the transmission has to shift a lot.

TCC Application in 2nd Gear – 4R75E Transmission
2005 – 2006 Ford Crown Victoria – 2005 – 2006 Ford E-150 – 2005 – 2006 Ford E-250 – 2005 – 2006 Ford Expedition – 2005 – 2006 Ford F-150 – 2005 – 2006 Mercury Grand Marquis – 2005 – 2006 Lincoln Town Car – 2005 – 2006 Lincoln Mark LT
Problem – A lack of power after the 1-2 shift can be caused by an un-commanded torque converter clutch application / TCC apply. The P0742 and/or P1742 DTCs may also be stored.
Solution – The #7 check ball inside of the valve body may have worn down to an incorrect size, allowing the torque converter clutch to apply after the 1-2 shift. Replacement of this check ball may solve the problem.

Slipping in All Forward Gears – 4R75E Transmission
2005 – 2006 Ford 4R75E Transmission
Problem – Many 2005 – 2006 Ford vehicles equipped with the 4R75E transmission, may experience excessive slipping in all forward gears. Metal shavings may also be present in the transmission fluid.
Solution – Replace forward clutch drum and update ECU with program 06B06

• Remanufactured valve body, with complete system correction and recalibration kit, improves pressure control and shift quality.
• Complete road simulation using a dynamometer testing program called C.A.R.S. (Computer Aided Road Simulation). Every transmission is cold and hot tested before shipment.

How to Buy a Remanufactured 4R75E / 4R75W Transmission

1) Buying Locally

When you go to your local repair shop, they’ll order a remanufactured 4R75E / 4R75W transmission, then mark up the price. So at the end of the day, you’ll be paying 15% to 30% more than the actual cost of the unit.

2) Buying Online

Buying a reman transmission through a company like Street Smart Transmission will save you a considerable amount of money because you pay the wholesale price (avoiding a repair shop’s 15% to 30% markup), they’ll ship the unit to the shop of your choice free of charge, and returning your old transmission is free as well. Then all you have to pay for is the labor to install the unit (usually $400 to $800), and you’re on your way.

How Does it Work?

To order a remanufactured 4R75E / 4R75W transmission from a company like Street Smart Transmission, all you need to do is provide your vehicle’s VIN number, the mileage, and the address of the repair shop that you want it shipped to.

Financing

Replacing a transmission can be expensive, so Street Smart Transmission offers financing through PayPal Credit. Depending on your credit, you’ll be able to order a new transmission, get back on the road, then pay for it over time. You may have to pay labor charges for the installation up front, but you won’t have to shell out for the transmission all at once.

Shipping Charge/Location

When it comes to shipping, a transmission is quite heavy. So you’re going to pay quite a bit of money, unless the reman transmission company offers free shipping. Street Smart offers free shipping to a business address, which is usually the repair shop that you’ve chosen to install the unit.

What is a Core Charge (Core Deposit)?

Every remanufactured transmission originally came from somebody else’s car. Therefore, they need your broken transmission in order to refurbish it for another customer.

Your old/damaged transmission is called a “core”, and many companies will collect a core charge (usually $500 to $1500), which will be refunded once they receive your old transmission. (Street Smart does not charge an up-front core charge.) Make sure to ask any company for their core return policy, so you’ll know what to expect.

Our Recommendation

We recommend Street Smart Transmission. We have found Street Smart to be of the highest quality. Their transmissions carry a 3 year / unlimited miles warranty that covers both parts and labor. Their warranty is nationwide and attached to the VIN so it is transferable with ownership if you decide to sell the vehicle. It also covers both parts and labor for the installation of the replacement transmission.

Finding a Shop to Install the Remanufactured Transmission
