Transmission Temp question
I bought a 2001 F350 PSD and the previous owner had a "power pull" transmission put in it. at 5800 bucks I really scored with full rebuild and triple disc etc. It came with a trans temp pillar guage. What temperatures should I expect when towing a 30 foot toy hauler? safe ranges? Any input would be great.

Never heard of a "power pull" transmission, and $5800 is a lot of money. I hope it works out for you. As far as temps are concerned, I typically see about 70-80 degrees above the outside air temp when towing my 14,000lb 5th wheel. Temps of 100 degress above outside air temp are not unheard of. Anything over about 220 degrees and you need to start letting it cool down by idling the motor with the transmission in park or neutral.

error in price
thanks for the info. The rest of the invoice found in the paperwork concludes the balance to be 3159. Newberg Transmissions in Oregon did the work. Apparently the power puller upgrade is installateion of shift enhancement kit, pillar temp guage, and auxillary cooler. Still a pretty nice bonus when buying a used truck.

The maximum continuous temperature is 225°F. You can go to 250°F for no more than 1/2 hour at a time. If it gets hot don't shut the engine off! Idle, or even better fast idle in park or neutral to cool the trans.
That assumes that the temperature is measured in the pan or the test port on the side of the trans. If the temperature is in the hot line to the coolers, use 300°F as your maximum.

Mark, I just want to thank you for being a part of this forum. I could've sworn when I was reading your above post that I was reading a technical manual for the Apache helicopter I fly. You just can't beat having someone with that degree of technical expertise as a resource here.
