Diesel and Trans ???
When I am going down the highway about 70mph or any speed actually if I let off the throttle and coast and I touch the brake peddle even lightly the RPM's will drop 300 to 500 rpm and appearently it downshifts or comes out of overdrive not sure. As soon as I let off the brake it will shift back into overdrive and the RPM's will go back up you can hear a slight sound diffrence almost like it is a braking system or something. I have had this truck over a year now and I just really started noticing it even thou it probably has always done it. just thought I would ask its just an odd that every time I let off the brake it shifts. Thanks Al
