another dead overdrive unit

You think the 518s are weak, try playing with a stock 545RFE. What a hunk of poo. When you press the button to put it in tow mode, it just turns off fifth gear. You're still in overdrive, and it hunts back and forth between 3rd and 4th. It's obnoxious.

The dealership rebuilt mine at 39,000 miles. 39,000 basically passenger car miles. I don't shift it into drive while rolling backwards, I don't rock it back and forth in snow or mud. I was pretty easy on that thing, and it burning up its clutches in a couple of years. The Hemi puts out more power than the transmission can handle. I'd glady trade it for a 518. I really miss not being able to go 1:1 while driving up a pass.
