Hi TSmith:
you have alot of good advice here. i have a couple of additional comments to expand upon my original response: JR2 recommends a heater pad on the transmission. i had one on a couple of my my rigs, but did not use it. 5 potential connections for my 4 recepticle junction box... . two battery blankets, block heater, heater pad for transmission and oil pan. i found that i opted to pass on plugging in the transmission pad. i have owned 22 vehicles and only one auto transmission (ford pinto nonetheless... took three weeks to come to grips with my foolishness and unloaded it). i felt that my manual trannys could get by w/out the heat. on the other hand, if i owned an auto, i would probably use the transmission pad and skip one battery blanket. it is no coincidence that auto trannys lose reverse in fbks... . first gear folks use after a cold start! ToolManTimTaylor recommends no idle. i fully concur. my strategy with gassers was to stumble outside, start it up, go back inside and have a cup of coffee. by then, everything inside the rig was toasty and some of the engine heat had conducted to the transmission. not so with a diesel. i would bundle up, coffee in hand, head outside, fire up my diesels, wait 30 seconds for the oil to flow and drive away. that's the best thing you can do. it is quite popular in fbks to idle away in the parking lot while shopping. no problem for a gasser, deadly for your diesel. the mass of your block is sufficient to retain plenty of heat to facilitate the next start at the shopping center. enough of my rambling. guess i just miss life on the "last frontier"! best, steve whalen
