IT (autobox ) will not shift ever, or slips or flares. or?
if its and A/T autotranny, tell me what it does right and wrong
here is an example.
i start engine.
i shift to drive car dont move, in any gear
i see RPM race high with right foot over 3000 RPM.
tranny failure. (slips)
or RPM stays near 1500, and engine sounds loaded,
and i find the parking brake stuck on, or the brakes are full of ice
and stuck fast.
