    You don't have to lock it out, it won't shift to OD in low range. Just curious why you are using low range. My '95 does just fine in hi 4wd. I just leave it in drive and go about 13-14 mph and the trans stays in 1st most of the time. Plus it's a lot nicer to back up in hi range.;)

    Much easier on the trans reverse band as well forward clutches. My driveway is built up,lots of up and down area . I also have a wet area where I stack the snow from the end of the driveway and part of the county road. Its just easier in low range to do everything. We got 48" of snow so far for the season and should be over 50" by nightfall.

    When I have the plow on the truck I turn off the OD.
    It is to hard on the tranny shifting in and out of OD all of the time And once in OD you are probably pushing harder on the gas just to maintain your speed so, your bogging the engine and wasting fuel and creating a lot of heat.

    OD is only useful at speeds over 45. with out the plow.

    Even in low range the tranny will shift in to OD. I would turn it off when you have the plow mounted on your truck ..JMO:waving:

    50 inches by nightfall!!! I'm on the north shore of Lake Superior and as I look across the lake All that I see is a big bank of clouds heading your way.payup

    Wind is picking up and getting darker outside it is starting again. Keweenaw is getting third storm in five days. 3-7" today another 3-6" tonight and maybe 4-10" tomorrow. It'll be time to plow again tomorrow. I don,t get too excited with any thing less then 6" of new snow on the ground.

    FYI the auto's are notorious for having OD issues- the OD unit is VERY pricy to replace and wears out more from city driving so it is recomended lock it out if you're not going to be driving on the highway (1800 rpm or higher sustained). Under 1800rpm, which translated to 40-45mph the line pressure is a bit weak and lets it slip on engagement. Fairly well documented ion the Dodge boards and confirmed by a few tranny specialists.

    The milage difference from locking out the OD is minimal (dropped me from 16MPG to 15MPG)

    I know the so called issues of the Dodge auto trans but my question came to mind while windrowing my driveway in LOW range. Must I use the overdrive lockout button in LOW range, does it try to lock in overdrive while in LOW range?
    I always lockout overdrive with plow on the highway but had not thought about Low range when the engine is at 2,000 rpm +.

    If you are in Low range it will not attempt to lock the OD- the PCM can't lock it so there's no worry. (lockup is based on speed and rpm- they have to be in certain ratios for the lockup otherwise no lockup. And TC lockup is different from OD lockup. OD can't lockup below something like 43MPH and will disable under 35mph once you step on the pedal- so no worry.

    My personal habit is to start the engine then immediatly lockout the OD all the time.

    Thanks for info, first year with this truck it's hard to teach a old dog new habits.
