4R100 Transmission Overview
In 1998, the E4OD was updated to the current 4R100 transmission. It was the last rendition of the C6 and the transmission is almost identical to the E4OD, but some of the internal components were adjusted to address the durability concerns that many truck owners raised. Issues would sometimes arise when the transmission was placed behind the powerful Powerstroke Diesel Engine.
The 4R100 was fitted with a power take off (PTO) in 1999 enabling auxiliary equipment to attach to heavy-duty trucks that had the transmission. Following Ford’s naming schemes, the E4OD was renamed to the 4R100.
The 4R100 is a heavy-duty four-speed automatic transmission used in rear-wheel drive trucks that have a 7.3-liter diesel engine. It was introduced in 1999 and quickly phased out after the 2003 model dropped. It was replaced by the 5R110W.
It is rated up to 1,000 foot-pounds of torque, which means it is extremely tough and one of the strongest transmissions on the market. The transmission itself is heavy-duty, but once owners start to add modifications to it, it becomes one of the weak points of the drivetrain.
If you have a truck that needs to carry a heavy load, you can depend on the 4R100, which offers a step 2.71 first gear that is excellent for towing. The overdrive gear ratio inside of the tranny is 0.71, which provides maximum fuel efficiency. The second gear ratio is at a 1.54 and the third is 1:1.
The 4R100 is a computer controlled transmission, which means it provides the ability to use a hand-held controller to customize the transmission, as you see fit. One of the most commonly tuned and customized options is the firmness of the shifts. Many truck owners want each shift to be as smooth as possible.
In addition, you can quickly and easily tune the rpms and line pressure of the transmission. If you want to throw some beefier tires on your truck, you can adjust your transmission settings to account for the larger diameter of the tire.

4R100 Transmission Technical Service Bulletins | TSBs
TSB 02–21–1 – 4R100 Transmission – Torque converter access plug may become dislodged
1989 – 1997 Ford Super Duty – 1989 – 1998 Ford F250 – 1989 – 1998 Ford F53 Motorhome – 1989 – 2003 Ford E-Series – 1989 – 2003 Ford F150 – 1999 – 2003 Ford Super Duty – 2000 – 2003 Ford Excursion – 1998 – 2003 Lincoln Navigator – 2002 – 2003 Lincoln Blackwood
Problem – Due to extreme load and material shrinkage, the torque converter external access dust plug may fall out during severe duty use.
Solution – Install new plug (part number E9TZ-7N171-A) with a 1/4 inch bead of silicone sealant around the plug.
TSB 98-20-9 – Ticking noise on initial startup when the selector is in park or neutral
1998 Ford Econoline – 1998 Ford Expedition – 1998 Ford F150 – 1998 Ford F250 – 1998 Lincoln Navigator – 1999 Ford F250 HD – 1999 Ford F350 – 1999 Ford Super Duty
Problem – A ticking noise may be hard when the vehicle is first started and the shifter is in the ‘P’ or ‘N’ position. In some cases, the noise may also be heard after the vehicle has warmed up. This can be caused by the overdrive clutch steel separator plate(s) hitting against the case internal spline.
Solution – Install new OD friction plates and accumulator assembly
Common 4R100 Transmission Problems
Poor performance with DTCs P0715, P0716 & P0717
Problem – Poor engine performance and acceleration may be due to a sticking solenoid regulator valv
Solution – If the solenoid regulator valve cannot be repaired, the valve body will have to be replaced
How to Improve the Transmission
While a hand-held tuner can offer you many of the basic adjustments your truck needs, some truck owners want additional options and the following are some accessories that can help strengthen the 4R100 transmission:
- Shift improver kits are designed to provide you with three options to adjust your transmission. You can adjust the tranny for off-road adventures, towing capabilities, and heavy-duty situations
- To extend the life of the torque converter, owners should choose lockup valve kits
- To help keep the transmission cool, add some extra capacity to it with a deep transmission pan in either aluminum or steel
- If you need your transmission to perform under heavy-duty situations, consider kevlar bands or clutch disks to ensure the transmission can work overtime without a problem
- Add an inline oil filter to ensure that no debris enters the transmission cooler or lines in the event that you experience total tranny failure
- Keep the temperature of the transmission as low as possible with an aftermarket transmission cooler with a built-in electric fan
- Transmission temperature gauge, which can help you monitor the overall temperature of the tranny itself and alert you when the temperature may be reaching that maximum 200 degree mark
- Customize your overall ride with heavy-duty stall converters, hardened pump drive tubes, and some anti-balloon plates
Remanufactured 4R100 Transmission Updates and Upgrades
- New pressure regulator valve, boost valve kit, bypass converter clutch sleeve, along with a plunger eliminate delayed engagement, soft shifting, and shudder
- Updated solenoid clips and EPC solenoid
- Updated 1-2 and 2-3 accumulator pistons to help prevent harsh shifting and premature clutch failure that may occur
- Upgraded spiral local snap ring and staked retainer to eliminate an OE design flaw and premature failure of the clutch
- New overdrive servo pin sleeve is installed in our unique servo modification process with custom bushings and tooling
- Completely remanufactured pump that includes new bore bushings to ensure that your transmission is durable and receives a better flow overall. The new bushings will eliminate any previous leaks that were experienced
- 2001 and newer models feature a 3-4 capacity valve sleeve and an extra thick zinc-coated Super Tough Plate that eliminates cross leaks and plate cracking that is caused by repeated stress from the 2-3 accumulator piston spring retainer
- Complete road simulation using C.A.R.S. (Computer Aided Road Simulation), which is a dynamometer testing program. All transmission are hot and cold tested prior to shipping
- Police, performance, and towing packages include additional valve body modifications, eight-plate direct clutch packs, elevated pressure regulator valve, and other upgrades to increase load capacity and durability
- Fully remanufactured torque converter is tested for lockup, leaks, balance, and concentricity. Upgrades all exceed the OE requirements and eliminate any possibility of premature brushing wear, front seal leaks, and vibration
- Remanufactured valve body comes with a complete system correction and a recalibration kit to improve the pressure control and quality of shift

How to Buy a Remanufactured 4R100 Transmission
1) Buying Locally
When you go to your local repair shop, they’ll order a remanufactured 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 distributor 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 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. 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. However, if the transmission case, or other key components are damaged beyond repair, you may not get all of your core charge back. Make sure to ask for the 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.

Will a F150 5.8 motor bolt up to a 4R100 transmission
I have a 1999 F350 super duty with 360,000 miles had rebuilt motor put in and rebuilt transmission. This is transmission number 4. It lasted 3 months and broke I was told a shaft inside broke completely into. This is the 2nd time I’ve been told that. What could cause that? I was going 35 mph when it happened and haven’t towed anything since it was installed.transmission shop has no idea
Rpm drops when sifting and at high speeds code ,625
I pulled a 36ft fifth wheel from Oregon to Nevada with my 1999 F-350super duty it drove find most the way but going up to Sis cues I kind of pushed it had to pull over a couple times let it cool down check tranny fluid the last 400 miles it drove fine parked it at my fiance’s place went to go move it the next day and it wouldn’t go nowhere but I do have reverse. I did a transmission filter and fluid change but I didn’t drain the torque converter. And I started it and was able to drive it it was jerky taking off but I drove it for a few miles and it seemed to get a little better but then I hooked up to the trailer got way halfway up the street had to stop and it wasn’t going anywhere try to back down park it. I’m just if it’s the torque converter if I do a complete flush if it might fix the problem.
Will a 4r100 out of an 03 f250 fit into a 05 f250 that had the 5r110 both have five four motors
Can can I put a 4r100 out of a 03 f250 with a 5.4 motor into a 05 f250 that has a 5-4 motor
2003 Ford F250 7.3L Diesel 178,000 miles. No check engine light. Runs great under normal conditions. Trans fluid full and clean. When pulling a horse trailer up a hill the engine or transmission goes back and forth from what may be high gear to a lower one gear rapidly. No warning lights come on. Sounds like a servo going on off on off
rpm jumped almost 3000rpms trans. sliping pulled over right away …no leak under truck no smell of burnt Anything , pulled dipstick everything Looked GOOD …colour full no burned oil …i was pulling a 5th wheel trailer …no BANG …nothing …is it the Torque Converter ? I have a 99 f350 diesel 352,000kms
I have a 99 f350 diesel…no leak …no burnt smell …oil looks and feels New …but…forward gears Slipping , Reverse seams OK…is it a torque converter problem …352,000 kms on truck
Transmission fluid is burning off no visible sign of leaks. Where is it going? 2003 Ford Excursion 5.4 gas
Transmission leaks and doesn’t want to perform when put in reverse and trying to back into an elevated camping space with a 5000# trailer. Transmission works well otherwise. Scared to drive anywhere there’s a possibility of having to back in a strain.
I STARTED OUT WITH NO FIRST GEAR IN MY 1999 F250 V-10 SD 4X4. What a dog! The engine seems to be running fine. No codes! So, praying it was something I could fix myself, I change the valve body, the auxiliary valve body and the solenoid pack. My new solenoid pack is Orange and I think the old one was black. Voila’! I got first gear back, but I still have a dog! It has no pep at all, but I don’t feel or hear any slippage. Then again, “I ain’t no expert!” LOL! It loves to run in third gear but it hates to run in fourth, shifting back and forth between 3rd and 4th between 70 & 80 MPH even on level ground. I drove from Lincoln, Montana to Bozeman, MT – a total distance of 153 miles. I used 29.2 miles per gallon! OMG! 5MPG? I’m 71 and on a fixed income. I cannot afford to drive it. Since the engine seems to run fine, I suspect the torque converter or the transmisson….or both!
I have a 2000 lincoln Navigator with transmission that delays and slips, however no DTC codes display. any ideas, suggestions?
