What is a 66RFE transmission?
The 66RFE transmission is a 6-speed automatic transmission that was first produced in 2012 for the gas engine Ram 2500 and 3500 trucks. The 66RFE transmission is considered to be a hybrid of the 68RFE and 545RE. The 66RFE transmission uses a 545RFE case but contains many of the same internals and gearset as the 68RFE.
How can you tell the difference between a 45RFE and a 545RFE?
The 45RFE and 545RFE are identical mechanically. The difference is in the software. Before you drop the transmission, though, pull the trans oil pan off and look at the valve body. On the passenger side of the main valve body is a cover plate that covers the accumulator pistons.

What’s the difference between a 45RFE and 66RFE transmission?
Chrysler’s new 45RFE transmission, launched in 1998, used three planetary gear sets instead of the normal two. The transmission evolved into the 545RFE, and then the 68RFE (2007), and the 66RFE (2012), a lighter-duty version of the 68RFE; the main differences between the various 6*RFEs are reportedly in the torque converter.
Is the 545RFE the same as the 66RFE?
An internal Chrysler communiqué to dealers summarized the change in a similar fashion. The 66RFE is a new transmission based on the same basic core as the 545RFE. It is similar to the 68RFE in basic construction, but differs in duty rating; for some of the possible differences, see the 68RFE page.

Why does the 545RFE have two overdrive gears?
The 545RFE has two overdrive gears that are fairly close to each other; engineer Bob Sheaves explained that this was because of the size available – the top 0.67:1 ratio gear was likely chosen because that was the largest one that could fit without making the transmission too large for the company’s vehicles.
