Service fill is 6–8 quarts plus transmission filter.Are you having problems fixing a 65RFE transmission? Are you looking forĦ5RFE transmission troubleshooting help, 65RFE rebuilding tips, 65RFE technical service bulletins, 65RFE diagnostics or technical information?ĭo you just have 65RFE questions and need some answers? Do you have diagnostic trouble codes (DTC's) and need 65RFE troubleshooting information? On the 68RFE, fourth gear is used for limp-in instead of second and third.Īll RFE transmissions use Mopar ATF +4. This design allows the vehicle to be driven (in “limp-in” mode) in the event of an electronic control system failure, or a situation that the Transmission Control Module (TCM) recognizes as potentially damaging to the transmission.

On the 45 and 545RFE the hydraulic control system design (without electronic assist) provides the transmission with PARK, REVERSE, NEUTRAL, SECOND, and THIRD gears, based solely on driver shift lever selection. The solenoid pack is mounted directly to the valve body its connector protrudes from a hole on the left side of the transmission. The TCM operates the solenoid pack to change hydraulic flow through the valve body to various clutches in the transmission. The TCM uses data from various transmission and engine sensors to control transmission shifting. Depending on year and application, it can either be a stand-alone module or integrated with the Powertrain Control Module (PCM). The fully electronic control is accomplished by the Transmission Control Module (TCM). 25 models with gas engines received the 66RFE, a hybrid of 68RFE internals (including the gearset) packaged in a 545RFE case. In normal drive mode, however, the 65RFE uses the shift pattern of the 545RFE thus never using 2nd and 3rd gears in succession. The key difference in the 65RFE is the ability to use all six forward gears in sequence when using Electronic Range Select mode. With the exception of an improved torque converter, it is physically the same as its predecessor.

2007–present Dodge Ram 25 Pickup (6.7L Cummins ISB Diesel)įor the 2012 model year, the 545RFE was recalibrated and introduced as the 65RFE in 1500 Ram models.

no 2nd gear prime for downshifting like the 45RFE and 545RFE transmissions.

revised gear ratios and Transmission Controller programming for larger application.

modified internal components to handle increased torque of diesel engine.

larger bellhousing with different bolt pattern and cutout to accommodate diesel engine.

The basic design and operation is the same or similar to the 45 and 545RFE counterparts with the following exceptions:

The 68RFE was introduced in 2 Pickups with the 6.7L Cummins ISB Diesel engine.

2007–present LTI/London Taxi Company TX4.

2005–2006 Jeep Liberty (Diesel applications).

5th 0.67:1 (545RFE only and 45RFE reprogrammed).

2nd Prime 1.50:1 (Only used when a kickdown acceleration).

The 45RFE later became the 5-speed 545RFE.

It was normally paired with the 4.7 L PowerTech V8. The 45RFE was produced at the Indiana Transmission plant in Kokomo, Indiana. Although, with some tuning, you can get the 545RFE to upshift into 2nd Prime. In the 545RFE four gears are used on the upshift and a new 'gear', 2nd Prime, was used with a different (1.50:1 rather than 1.67:1) ratio to increase versatility when downshifting. In the 45RFE applications four gears are utilized. It also features three multiple disc input clutches, three multiple disc holding clutches, and a dual internal filter system (one primary filter for transmission sump, one for the fluid cooler return system). The 45RFE was introduced in the Jeep Grand Cherokee in 1999, it is notable for including three planetary gearsets rather than the two normally used in a 4-speed automatic.
