K-2500 GMC 7.5' Western straight blade, stainless tailgate spreader, 350 auto 4wd.
C-70 Chevy dump truck, 10' Western HD straight blade, under tailgate spreader, 366 c.i.d. gas engine 4 spd manual transmission, 2 spd rear end.
Wouldn't want an auto in a dump that big (yes I know Allison make one for it but I'm set in my ways) and wouldn't do without one in the four wheel pick up.
My first plow truck was a GMC K35 with a 4-speed. I don't know if a manual would be ok for long runs, like roads, or long driveways with one pass one way then one pass the other, but for lots, with all that back and forth shifting, and frequent starts and stops, never again. Too hard on the clutch, and you have to wind the engine up to the redline to get any speed in reverse, which is the gear where you spend half the night anyway....
If it were a dedicated plow truck I'd consider the Allison for a medium duty dump, but as an excavator, I'd agree with keeping with a 4 and 2 or even better, a 5 and 2 in that size dump.
I've got an auto in my driveway truck and a stick in my street truck. The auto's are good for jobs where you have a lot of backing, otherwise a stick is more durable and as ctfireman said, easier to work on.
If only someone would put a shuttle transmission in a pickup....
Allison Auto here, why? because it is the baddest auto made for a light duty truck, it's matted to the 300hp and 520ft lb of tq 6.6 L diesel. Sorry, gets me goin when I tell everyone I have an allison auto in my truck.....
Well I've had both & think a heavy duty auto with extra coolers is best for me. I've rebuilt autos & put in clutches over the years so it doesn't really mater that way. If you go auto make sure you chang the fluid & filter before & after the season, & sometimes even in the middle of the plow season. Only one time did I loose a trany in plowing & that was because it had over 125,000 hard miles. Brent
Auto, because reverse is usually a ratio between 1st and 2nd, where standards always seem to have a lower then 1st reverse!
so they are slower for plowing. A properly cared for auto will kast as long as a standard, but they take more operator training, you can't shift a standard into reverse while going forward. What we need is a special plow gear box with a high ratio reverse, or how about a transfer case that kicks into high range, from low range when you shift into reverse?
Try www.transferflow.com, they make a 44 gal take for our trucks. they also make a 98 gal aux tank that goes in the bed. Anyway, that is great mileage considering a gaser, I am about 16 to 19 depending on load, foot placement, and fun factor. Anyway good luck to you.
