    Hi guys,

    I am operating a KW t800 2010 (18 speeds, cummins isx15) and the sppedo does not work under 35 km/h (the needle stay at zero) so during that time the rpm is limited to 1600rpm, not great to start uphill!!! But works great when speed is over 35 km/h...

    Does anyone knows a quick fix or where to look to solve that???

    Thanks. 20180920_135205_HDR.jpg

    I had that problem on my Freightliner after changing speed sensor. Gap was too wide. Try tightening sensor located on tailshaft. Turn in till bottoms out and back off a bit.Or just turn (tighten clockwise) a little bit at a time till it starts working.
