I'm thinking of putting one of these on the Silverado. Anyone had any experience with the concept of
increasing the oil supply to keep it cooler?

Followup to my last ...

I assume your Silverado has a transmission fluid temp gauge as well as
an engine temp gauge. My Ford F-250 Super Duty does, I know. If I were
noticing higher than normal transmission temps while towing I'd be more
inclined to add an axillary transmission fluid cooler rather than just
increase the capacity of the transmission pan.

If I am not mistaken your truck has the Allison transmission. From what
I've heard, it is a superb transmission for towing ... probably the best
thing GM has going for it in their trucks. Unless it's getting hotter
than normal, I'd leave it alone. Just my humble opinion.


Here's an interesting and informative piece about Allison transmissions. I'll probably just leave
mine alone for a while. I've never seen the temp get much over 200.

The Pace Arrow Class A motorhome we had for a while had an Allison
transmission. It was the only thing I liked about the whole rig.

Ford sorta copied some of the operating characteristics of the Allison
in the "TorqueShift" transmission used in the Super Duty Series. It
operates similarly to the Allison, including different gear ratios on
the downshifts than the upshifts.

One thing common to both that I assume you do ... always use the
"Tow/Haul" mode when towing. Otherwise, it *may* get hotter than normal.


That is on my checklist. This sits on my dash:

DEPARTURE

" TOW/HAUL MODE
" JACKS 'OFF'
" HITCH FORWARD
" HITCH LOCKED
" TRAILER BRAKE
" REGRIGERATOR GAS
" TAIL LIGHTS
" WALK AROUND
" GET WIFE

Except for the last, I've forgotten all of them at least once!
