the over drive when going down the road the overdrive makes the pickup pull back forth
Are you hauling or towing anything?
The owners manual for my 2010 states if I am pulling a load or have a load in the bed, the overdrive should not be used.
That is right, it will burn out the trans, that kinda sounds like what they call torque converter shutter, could be a bad converter or a lockup solenoid.
