May be more info than you want, but here is what I found on the solenoid pack requirements:
Any 545RFE or 68RFE will bolt up to the Jeep Liberty. (5 or 6 speed is controlled by the TCM)
Later model transmissions used a different solenoid pack (
GRAY Connector) that is NOT compatible with the 05-06 model electronics. (TCM)
So you may have to remove your solenoid pack from your current tranny and install it in any newer 545RFE you purchase.
They are identified by their color.
If you are using a later model Hemi transmission like the 68RFE, you will have to swap the solenoid pack back to the earlier model (
WHITE Connector) solenoid pack which is compatible with the Jeep CRD's TCM (electronics). Just make sure to use the one with the
white connector.
Read more, it gets a little deeper:
WHITE-CONNECTOR SOLENOID BLOCKSThe white-connector solenoid block (Figure 4) came out in 2004 with an updated (type 2) transmission range sensor plate. You’ll see these solenoid blocks used with the 545RFE and 68RFE transmissions.
GRAY-CONNECTOR SOLENOID BLOCKSThe gray-connector solenoid block came out in 2009 and has one less solenoid than the white-connector solenoid. It uses the same base gasket as the white-connector solenoid block.
The transmission range sensor plate is where the confusion starts. From 2009 to around 2011, it’ll still use the type-2 transmission range sensor plate, which works with vehicles that have manual 1 and manual 2 positions on the shifter.
There’s no cutoff day on the change to the type-3 transmission range sensor plate. The type-3 transmission range sensor plate has a pocket depth of 0.158” (4.0mm) and the side of the manual valve slot will be 0.500” (12.7mm). This type-3 plate fits vehicles without manual 1 or manual 2 shifter positions.
You can replace the gray-connector solenoid block with a white-connector solenoid block, as long as you use the right transmission range sensor plate: Type 2 with cars that have manual 1 and manual 2 on the shifter, type 3 if it just has Drive on the shifter.
A little attention to the details will help you avoid confusion when swapping RFE transmissions.
