I have 2 oil pan heaters on mine for those trip up north. Brrrrr Darn tropics down here. I have had to the following if all else fails. Blue tarp and camp stove. Let it run for an hour or so and it can get somewhat warm under the tarp. Had my fuel lines freeze up in Glennallen one winter at -60. Was the only thing that got it running.

Would anyone advise also placing a heater on their tranny pan?
