The marrying of the 68RFE transmission in a Dodge is almost as important as the marrying of a Cummins in a Dodge. For YEARS, Dodge has put lackluster transmissions behind the Cummins powerhouse, and have regrettably developed a poor reputation for it. When the 2007.5 6.7L was released, it came featuring the 68RFE, and it was proven to be a good choice. This new six speed automatic has proven itself to be able to handle a TON more abuse compared to its predecessors. But with any transmission, it has its limitations.
There are many of those whom have already pushed the limits of their transmission with performance enhancements and hauling heavy loads that know all too well how much is too much for the 68RFE. BD transmissions are designed to take on what most 68RFE owners are looking for - responding with smooth sharp shifts to keep the engine in the torque range required.
BD has done extensive research to determine the failure points of the 68RFE and to correct them. For instance, BD's 68RFE pumps have a new regulator valve design, and along with a new valve body separator plate and pressure control module, can deliver up to 250 PSI clutch apply pressure. This provides 150% MORE holding force above stock, in order to help prevent clutch slippage. Also, BD's 68RFE Electronic Pressure Controller dynamically adjusts the hydraulic apply pressures based on APPS, which is used in governing engine loads and responsiveness through transmission gear selection. the module's dynamic control ramps up in the much larger sweep right up to 250 PSI mainline pressure as needed dynamically. This is NOT accomplished with any other aftermarket engine tuner.
All the clutch packs and drums have new machined designs with the maximum amount of heat/energy/capacity in mind. Special machining has been done to the second gear piston to incorporate additional thick as stock clutch fiber and steel plates. The fourth gear apply piston has been modified to accept new heavier BILLET retainer and a steel girdle is applied to strengthen the piston and give a broader apply area.
The low and reverse sprag clutch with dog-bone style dawgs that bind and wedge themselves into destruction are also replaced with a BD EXCLUSIVE, heavy duty constructed cam and roller style one-way clutch, preventing these explosive failures.
Each transmission is dyno tested and comes with BD's heavy duty deep sump aluminum transmission pan to add strength to the case preventing flexing and internal oil leakage.
In comparison to the standard Performance Series 68RFE transmission from BD, this transmission package includes a BILLET input shaft for unrivaled strength where you need it most. These shafts are built from 300M billet steel alloy to an extremely high yield strength. Further, they are heat treated and precision ground, as well as gun drilled through the hole to eliminate stress risers that are associated with conventional drilling procedures.
BD BIG STACK ADDITIONAL INFORMATION: The factory 68RFE features a poorly designed overdrive clutch pack and shaft, which can lead to premature failure of the transmission. While many companies will merely produce thinner clutches in order to increase the clutch count, because the clutches are already relatively thin, in the 68RFE this is not the best option. BD determined a method that when combined with their Big Stack Overdrive Shaft, allows for additional clutches made from QT100 for less deflection, less wear, and substantially more holding capacity.
- BD's large overdrive clutch spline and beefy high strength billet QT100 reaction plates ensure less deflection and more uniform clutch face engagement.
- BD's exclusive design gives an additional four overdrive clutches - 16 total - for torque holding capacity of 33% over stock!
WARRANTY - 36-month / 150,000 mile limited warranty on non competitive, racing or sled-pulling applications. See warranty statement for further details. In order to receive warranty, you MUST fill out and return to BD their 68RFE Warranty Form, found. Failure to fill out and return this form will result in the forfeiture of any warranty or technical support by BD. Please read through the requirements before purchase to confirm you are able to take all of the required readings.
CORE CHARGES - An upfront core charge is required. Once your core transmission is received and processed by BD, we will promptly issue credit back to you. Please contact us if you have any questions.
SHIPPING POLICY - Due to the size and weight of transmissions, they cannot be shipped through traditional couriers, such as UPS, FedEx, USPS, etc. and MUST be shipped via truck freight. We do not offer free shipping on transmissions, however, we do offer a very competitive flat rate charge that is added to your shopping cart at checkout. Further, to aid in returning your core transmission, we give you the option to be billed up front for the core return and we will coordinate the pickup and return of your transmission. Once your core transmission is ready for pick up, you just need to give us a call or send us an e-mail with your original order number and the core tag on the transmission, and we'll take care of the rest. Otherwise, we give you the option to coordinate the return shipping on your own and independently pay your courier of choice. As always, if you have any questions, give us a call or send us an e-mail.

One other question please.. Do I need the billet shaft if I am around 700 hp and will NOT be racing or sled pulling? Thanks again for your help, Sam?
I would still recommend the billet shafts with that HP level. Due to the size and design of the factory shafts you would want to go with the billet as you will be using a triple disc converter.
How many max horsepower is recommended for this trans? I have a 2009 Ram 2500 with aprox 700 horsepower.. Thanks, Sam?
That Transmission will hold 700hp reliably depending on application. If this is a truck that is used for competition sled pulling or drag racing we would recommend another option, possibly a 48RE conversion.
WHAT IS THE MAX HORSE POWER RATING ON THIS TRANSMISSION? THANKS!?
That Transmission will hold 700hp reliably depending on application. If this is a truck that is used for heavy towing at high HP, competition sled pulling, or drag racing we would recommend another option, possibly a 48RE conversion.
what kind of warranty do you offer with certified installation??
In order to receive ANY warranty or technical support, you must also install a new BD torque converter at the time of transmission installation. The warranty behind these are 3 Year, 150K warranty.
I'm currently experiencing intermittent shift problems in 2,3,4 and some clunk at shift down. What can I expect different from a factory trans over a rebuilt unit. ""Do I need to return a core"" . Can you rebuild my trans. instead of a exchange. What fuel mileage will be getting a gear change. I'm averaging 24mpg. NOTE: I did notice a shaft change and a Torque Converter change. Sad thing! It's still under Warranty. Try having a dealer in this area Warranty it, It's almost impossible. Mileage is 43,000. It was purchase in Meneola TX in 08-2016 with 38,000 miles on it. Vehicle is Heavy Duty RAM 2500 No Four Wheel Drive. What fuel mileage will be getting a gear change Thank you Bryan.?
Couple of upgrades that are going to make this transmission better then stock. One being the billet input shaft, these are much much stronger then factory inputs to handle aggressive shifts and high horsepower. Other updates are modified valve body to increase line pressure and holding power and have firmer shifts. And a upgraded low/reverse sprag clutch, all in the interest of reliability and longevity. You don't have to return a core if you don't want to you will just be charged the core. This transmission is not going to improve your fuel economy over what you have right now.
what deference in fuel mileage can I expect. I'm currently ranging around 24mpg with OEM Trans. My unit is a 2500, 2014 RAM, non four-wheel drive, OEM 18""tires. Better yet its all Factory still.?
This transmission would yield no MPG gains, It is suited for a modified application with higher hp.
Would this transmission fit my 2014 Cummins??
Depends on your application, 2500/3500? What transmission is in the truck currently?
I currently have a 68rfe transmission on my 2014 ram 2500.. can I use this transmission??
Yes, these are as listed for the 07.5-17 68RFE
