/Edit (July 2009)
Given:
2003 Durango, 5.9 46RE
65,xxx miles
7/70,000 warrenty
Tranny fluid was changed by dealer ship @ 30,000
The problem:
In the last 5,000 miles I had..
1. Tranny code, clear it.
It came back, but the light went away. (Kicker is I though this was stored in memory and I can't find the paper I wrote the code down on...)
2. Hauled a 4,000 lbs trailer 260 miles. With OD off I got 8.6 MPG.
(Note I've hauled the same trailer all last summer, I got 10.2 every time. Give or take .1 for wind)
3. Backing up the tailer I need 500-800 more RPM to make it up a steep hill.
So I take it into the dealer. (Charges me 1 hour labor)
No Codes, and computer codes were reset 111 starts ago.
Their test drive was without a trailer (I've never had an issue without the trailer.)
He say nothing wrong other than it's a 1/2 quart low on fluid.
Also said I shouldn't tow in overdrive, said it over heats the tranny and thus my issues. (Note: I NEVER drive in OD while towing! EVER!)
