Towing in Overdrive ???
Ok I know this must have been covered before, but I can't find it. So, here goes....
I have a 5.4 SD Auto with 3.73's and a 4000lbs trailer. I have done a couple of 500+ mile highway pulls though the Northeast states. The Owners manual says to use Drive for climbing long hills and select a lower gear for long decents. I have been keeping it in Drive and tach-ing around 3000 rpms when going up and down lots of hills. I try to keep it in "OD" as much as possible. If the grade and speed allow, the rpms to stay about 2250 while in "OD" and the truck pulls fine. There are times where every few miles I find myself going from "D" to "OD" and back.
Question is how much shifting the auto is too much? OR, is it better to tach the engine at 3000 rpms all day?
Thanks, Steve.

I tow a 5000lb camping trailer w/ mine and do the same as you. I try to stay in OD unless it starts to get hilly, then i lock it out. I read around 3000 rpm in D and about 2250 in OD. I would liek to hear what others are doing.

I pull 10,000 lbs with my V-10 and usually always leave it in overdrive, unless there is a really steep grade. The powerband is around 3400 RPM for mine. Don't know what your is, but the Triton's all wind up pretty tight.

[updated:LAST EDITED ON 20-Jun-02 AT 09:14 PM (EST)]I pull a 5,000 rv with my
V10 in od from Fl to the Smokies twice a year and have no
trouble at all till I get about Knoxvill on I 40 then she kiks into
D a few times. When she starts to "hunt" I just click off the OD till
it levels off a bit. Outside of that, she pulls @ 65-75 just fine in D.
