    I can try that, cant wait! I would not have thought to try it downshifting but I will, I can do the 7 and 8 without the clutch now, is it the same? Just kinda gently tap/bump it in until it matches up and goes? I assume the truck should be slowing down as well as dropping rpms? If it tries to...

    Awesome, thank you! Yes, it does have low range in the transfer case as well as transmission, obviously ha. I'll try it out in Low range first sure, thanks. I would have never thought to try to learn in low, all that tourque doesn't make it more difficult? or is that the point? I'll do it, thanks.

    Eaton 8LL, can't downshift w/out a complete stop. Will trade labor for lessons/ride-along (or cash$) in RENO/SPARKS, NV area.

    I recently bought a '98 Mack RD690P Dump. I am pricking up on everything else very quickly, but can not downshift without coming to a complete stop, I haven't even got lucky one time, just can't get it sorted out. Fortunately it has great breaks, but I am yet to haul anything, and don't plan to...
