Towing RPMs

[Jeff. State]

I'm hoping some can chime in with thoughts on an optimal RPM while towing for MPG, egt, and not putting too much strain on an Auto tranny.


Thanks.

What year are you looking at?

I pull with an '07 F350 with the 6.0L and 5R110, with 4.30's in the axles. Towing, I like to keep the tach somewhere in the 2000-2250 range cruising. What I use for my limitations on towing is my EGT and Trans Temp guages (aftermarket, not the factory monitor on the dash). If EGT nears 1100*, Oil or Coolant nears 220*, or Trans gets to 195*, I'm backing off or downshifting.

With a 4R100, I like it about 2200 or so.
The trans will be fine, unless you start adding power beyond what it can hold.
If it's a 4R, a valve body and a good trans cooler does wonders.
