The 68RFE was introduced in 2007 Ram 2500 and 3500 Pickups with the 6.7L Cummins ISB Diesel engine. The basic design and operation is the same or similar to the 45 and 545RFE counterparts with the following exceptions:
-Larger bellhousing with different bolt pattern and cutout to accommodate diesel engine.
-Modified internal components to handle increased torque of diesel engine.
-Revised gear ratios and Transmission Controller programming for larger application.
-No 2nd gear prime for downshifting like the 45RFE and 545RFE transmissions.

68RFE Technical Service Bulletins | TSBs
TSB 18-037-07 REV A – Low line pressure – 68RFE transmission
2007 Ram 2500 – 2007 Ram 3500
Problem – Drivers may experience an illuminated check engine light, with a P0868 DTC.
Solution – This may be due to a malfunctioning TCM, which may be cured with a software update.
TSB 21-010-12 – Clunk noise when shifting from drive to neutral – 68RFE transmission
2011 – 2012 Ram 1500 – 2011- 2012 Ram 2500 – 2011 – 2012 Ram 3500 Cab Chassis – 2011 – 2012 Dodge Durango – 2011 – 2012 Jeep Grand Cherokee
Problem – Drivers may notice a pronounced clunking noise when shifting from drive to neutral. This may be particularly evident when the outside temperature is hot.
Solution – These 68RFE transmission problems may be caused by the underdrive clutch releasing too quickly. To correct the issue a revised spacer plate will need to be installed inside of the valve body.
Common 68RFE Transmission Problems
Slipping, Erratic Shifting, Harsh Forward or Reverse Gear Engagement: Some of the most common 68RFE transmission problems are slipping between gears, erratic up or down shifts, or a hard slam when the 68RFE 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.
Sudden shift to neutral after takeoff
68RFE transmission
Problem – Drivers may notice that the vehicle suddenly shifts into neutral after trying to pull away in Drive. There may also be a P0721 and P0933 DTC.
Solution – The 68RFE low sprag inside of the gearbox has most likely failed.
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.
Updates to Remanufactured 68RFE Transmissions
- Fully remanufactured valve body includes updated solenoid switch valves for improved shifting, lubrication, and performance.
- Fully remanufactured torque converter is tested for leaks, lockup, concentricity, and balance. Upgrades exceed OE requirements and eliminate the possibility of front seal leaks, premature bushing wear, and vibration.
- Completely remanufactured pump, complete with updated TCC limit valve and TCC accumulator to ensure proper TCC control and cooler flow, provides consistent internal pressures, eliminating slippage and delayed engagement.
- New line pressure sensor maintains consistent shift quality.
- Secured accumulator cover bolts prevent loss of 3rd or 4th gear.
- Fully remanufactured solenoid packs are tested separately from the transmission before dyno testing to verify shift quality and pressure control.
- All-new custom-spec bushings improve internal fluid flow control and pressures.
- Bushings and machined surfaces polished to a mirror-like OE finish of 16 RA or less.
- Complete system correction and recalibration kit installed to address several OE flaws. Modifications include updates to servos, the PR system, and valve body accumulators.
- Heavy-duty recalibration kit installed to reduce slippage and increase durability.
- 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 68RFE Transmission
1) Buying Locally
When you go to your local repair shop, they’ll order a remanufactured 68RFE 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 68RFE 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.

What Transmission Do I Have?
Turn a corner slow enough to go into 1st gear, the truck will not move. Goes into reverse good but will not go forward until you shut the truck off. if you slow down to a complete stop you feel a banging like the transmission is going into first gear hard from a higher gear, you can drive after that. No bang no moving.
When I slow down from a speed about 25 to a stop sign when the transmission drops down to first gear I get a real hard Rumble when I put the truck in neutral on a slow down I don’t have that
Jumps out of 1st gear kill engine and restart goes i 1st jumps out in about 10ft have change fluid filters and shift solinoid same problem
Same thing happened to me today
Hit a bump and transmission quit pulling in any gear. 2016 2500 4×4 diesel
