Thanks for the replies! When I first read the text you quoted from allpar.com
it wasn't clear to me that there were SIX available forward gear
ratios, five used during upshift and a second Second gear (1.50:1) used
during downshift. Pretty smart transmission!
Any idea what they meant by stating, "... [with the 5-45RFE,] Chrysler
is able to 'electronically' get another ratio out of the 45RFE
planetary gearset"? What electronic wizardry gets us another
ratio? Is it truly five unique planetary gear combinations on the
way up? Is the second overdrive an additional physical ratio?
I really appreciate the education. When you've got the first HEMI
on the block, you get lots of questions from friends and
acquaintances. I need to UNlearn the misinformation (ie. the
dealer said this was a Mercedes 5-speed, which allpar.com
specifically denies) and replace it with actual facts.
ps. I also renamed the thread from "545RE" to "545RFE". Typos don't
help search results.
