C6 in park

I have a '91 F350 with 300-6 and a C6 transmission. I hook a trailer to this truck with a winch on it and load heavy Mesquite logs by dragging them up a ramp onto the trailer. I leave the engine running to keep the battery from running down and the transmission in park to prevent the truck from rolling backwards. How strong is the park gear? Can this hurt it?

I've never heard of one breaking, but I always tell people if you saw what "park" actually was in a transmission you'd probably treat it different. I'd definately use the parking brake too as that's what it's there for.

No idea how strong it is, but that much tension may be enough to break it.

Personally I'd stop the truck in neutral and put the parking brake on, then block the tires, finally I'd put the transmission in park. All that weight being held back by the park gear only is never a good thing.

Agreed. The parking pawl is just a pin in your tranny. Take the load off of the driveline by setting the brake (which works best for forward motion but will let you reverse even when fully applied and adjusted) and block at least one front and one rear wheel. Then keep the engine in neutral when wenching. If the truck moves, use better blocks. Tow trucks use an anchor, even if it is the wheel lift planted in the ground.

I've rebuilt a few automatic transmissions myself, and have seen only one that the parking pawl was broken. That was caused by someone throwing it in park while it was still rolling forward one too many times.

I would follow the others advice and not use it as your only means of keeping the truck stationary. While it would probably take a while to cause any significant damage, it really can't be all that good for it. Blocking the wheels is probably your best bet, unless you can anchor the truck to some other stationary item such as a tree or pole.

One time, I was pulling a 3500 lb sailboat out of the water, and I had to adjust the truck, so i hopped in, popped the e-bake, reversed a tiny bit, and forgot to set the brake the 2nd time, just park. It came out of park with a loud bang...I won't do it again.

Thanks to all for the information. I am going to stop doing it this way and go back to the way I used to do it with a standard transmission. Leave it in neutral and put my push gadget between the seat and the brake pedal. Locks all four wheels. It was just so darn simple to put it in park.

Best way to do it. Lock all 4 wheels. J.C. Whitney used to sell a valve that tied into the brake lines. You could flip the switch and pump your brakes and they would stay locked. I put one on my '67 Wagoneer. Worked great for the wench. I don't know if they still sell them but it worked great for me.

You can get line locks from summit, jegs, and probably still jc whitney.
The only bad thing about that is if you leave it on to long it can make the rubber brake lines swell. They tell you in the directions not to use them for more then 30 or 60 seconds.

I like the idea of the brake line lock but I need to leave it on for 5 to 10 minutes at a time. So that may not work for me.

What about a transmission brake? I've seen people put them on drag cars all the time... I wonder if something like that would work here?
