auto trans upgrades for towing

[qtrhors]

Have a 28 ft 5th wheel Im leaving with for Portland Or from Billings Mt. Some grade to deal with My question is what mods have you guys done or like for the auto trans. Now this may sound like a pretty dumb question but does my rig have a factory external tranny cooler?(no I havnt looked yet). What type/size? What should I get? Im thinking a better tranny pan too Suggestions? thanx.

Unless you get a full "heavy duty" rebuild, there are no bolt-on parts you can add to the transmission to make it stronger (valve body, torque converter, etc.). None of these parts make the transmission itself any stronger.

A larger transmission pan won't do anything but add fluid capacity. It won't add strength or cooling efficiency as there is just more hot fluid to extract heat from at that point.

The transmission cooler you have stock will be a little guy located between the A/C condenser and the intercooler near the bottom. It never hurts to add a bigger cooler.

I found the tranny cooler? I guess I well just have the tranny serviced(replace filter and fluid). Cody your comment about cooling efficiency is interesting. I have heard that increased pan capacity actually helps with cooling because the fluid stays in pan longer account more fluid volume and a finned aluminum pan helps this process.

From what all I have read about bigger pans,coolers,etc. It seems that unless you upgrade your cooler it's not a great idea to get a deeper pan for the fact that once the fluid does heat up it takes longer to cool down in my opinion I would either add a larger cooler and a deep pan or just a larger cooler

Sounds reasonable to me Im no pro tech guy. Im just a hobby/tinker around guy at best. I have messed around with cars some...once upon time I had several "hot rods" including mid 11 sec stang. Getting the tranny flushed with filter and fluid change tomorrow. Going to head out thur morning.

Have a good trip. I've taken that trip a couple of times but my destination was the Tillamook area. I like it there a lot.

Save your money on the transmission pan. They look neat and that's about it.
