hi,
Im new here I just want to know it is also applicable to my Isuzu trooper 3.1 diesel. I have a problem my speedometer is dead and the check trans is blinking. When I replaced a new speed sensor the speedometer works again I think it was already corrected the problem. I notice to my trooper the check trans start blinking again every 1.8 KM over and over again. I think I have to clear the DTC. Is this is the procedure to clear the DTC in TCM?

Thanks,
Nap
