Has anyone successfully swapped a Dodge PU tranny 545rfe or 65rfe into their CRD? I can get a '15 65rfe for about half the stock trans, but I don't want to spend the next month making it work. I understand the TC should be upgraded, anything else? What is the difference in driving?

Take a look at this thread, this thread, and this thread. They should answer pretty much every question you may have.

The big difference in driving is that second prime now becomes part of the normal shift sequence rather than only available under kickdown; this was accomplished through a software change. Other than that, the 545RFE and 65RFE are more or less identical.

You can use a 65rfe but will have to swap over the valve body and solenoid pack from your 545rfe.

Thank you both, been doing more research. Does anyone know if the 65rfe out of a '15 Dodge 1500 would have the same TC as my 545rfe? Now I'm considering a rebuilt 545rfe from https://www.detroitaxle.com/, not that much more than the used 65rfe, and it sounds like they will install upgrades for me, but if the 65rfe already has an upgraded TC, then that might be the difference for me. Going to talk to them today, see what kind of upgrades they can offer me, and if it would still carry the 3 year/30k warrantee.

Things to consider on the Dodge 545rfe.
Gasser's torque converters have higher stall speeds than the Jeep CRD.
Some have used the Hemi transmission/TC but do report the higher stall speed of the TC.
A 15 I believe has to have the solenoid pack swapped back to the earlier model solenoid pack which is compatible with the Jeep CRD's TCM (electronics).
Any transmission/Torque converter they are quoting you if it is designed to go behind any engine other than the Hemi I believe the torque converter would be way to weak in the long run for the Jeep Diesel's higher torque output.
Bottom line, If you can go with the Hemi transmission and are willing to swap out the solenoid pack and you are willing to live with the higher stall speed, you will be ok going with a 545rfe out of gas powered Dodge. :juggle:
