    What are you driving that your motor lugs at 1000/2000 rpms? My motorcycle struggles at those RPMs, but at 2000 rpms my truck is right about at the redline. At 1000 it isn't lugging yet, although it is below the optimum rpms.

    Most of the time when I downshift, I do let the rpms drop quite a bit, but that's because I'm usually dropping two or more gears at a time as I'm coming to a stop. I don't like redlining the engine when I downshift, so I let the rpms drop pretty low. I don't let it lug, per se, but it might do so it I were to try to take off again without downshifting at those rpms. In my truck that's anywhere from 6-800 rpms. Every truck is different.In a truck I use to drive I could upshift to where the rpms dropped down to 600 and the engine wouldn't lug. YMMV.

    If I'm downshifting because the speed limit is dropping, or for some other reason where I'm slowing down but not stopping, I shift a little bit higher, but I still prefer to keep it lower rather than running the rpms higher in the lower gear. If I'm downshifting because I have to for an uphill climb, I like to keep the rpms as high as possible.

    Have you consulted the manual for the truck? It should say something about the ranges where you should shift.

    Garbage trucks and the like are even lower. They're x100. The first time I saw that, scratched my head.

    Really, thought be the opposite, either or I don't think op can downshift at 2000. I think I can at 1500 if I really try

    @ajohnson, nevermind my post. The tach goes into the 1000's like normal truck as well. You just never reach it crawling around town. So your always at like 7-900 Rpms

    Never drove a garbage truck,.but in my town they only drive about 100 ft between stops so I imagine they are not getting reved very high. Does using the crusher bring rpms up?
