3500 2001. Its a tad complicated...you or him? 2001 gmc
its a tad complicated...you or him? 2001 gmc sierra 3500 dually RWD ... power loss...Guys - '01 3500 Sierra Dually RWD 6.6L Duramax, w/ Allison. Cruising flat highways and on ramp speed up are no issues. However, up hill (whether towing or not) and kicking down the tranny to lower gear the following happens: dash lights, radio, seemingly the ignition circuit and a loss of power occurs after about 10-20 seconds after starting the hill. Only solution is to remove foot off accelerator and everything comes back on and carries on. To take the hill I must stay around 50 MPH, to avoid tranny shifting? This is a ground issue, isnt it? Is it possible that the tranny and the dash (and/or ignition circuit) are all grounded to the same hard point, that is faulty, perhaps?!? any idea what may be causing this kind of power loss? and gas pedal or tranny/ dash shutdown combination?… read more
