The car will start and the engine runs normally, but if I put the car into drive or reverse, the wheels won’t move. The engine revs normally as though it were in park but the wheels won’t turn!  The car is a Toyota Avalon 1997, automatic transmission. It has been buried in the snow for the past week. Last time I drove it was just over a week ago. It was running fine. Help

just curious....   how cold did it get ????

transmission fluids turn to a solid at -45 F or so...

since the transmission is a fluid pressure operated device. if the fluid was turned to jell... do to the extreme cold weather.. trying to operate it will damage it until the weather warms up slightly...

up in the far north.. a few years back...  when the temps reached -45 to -50F...   the pick up trucks are just left sitting idling all night.. or they will never start...

at some point during this extreme cold snap... and do to a change  in a line of code on how the transmission operates...  the software was programmed at -45F to turn on the torque converter clutch... this spun the parts inside the transmission..  the problem was..  the fluid in the cooler lines had turned solid..  since the fluid from the cooler lines also supplied pressure lube to various reduction gears inside.. they burned up..    the owners came out .. tried to put it into gear only to find the transmission had failed..   one mechanic knew it was going to be a bad day.. as there were over 50 almost brand new trucks that the tow trucks had brought in over the weekend with totally destroyed transmissions...   worst part.. there were not enough parts to go around..  it was a new design.. all the parts were going directly to the transmission plant for new truck production..

is your car still caked in ice preventing the wheels from turning.. or preventing the car from moving as the wheels spin in place...   remember.. this has an open differential.. you might not see the other side spinning...  if one side is locked in place..

another thing.. when the car is in park...  and the parking brake is off...   can you rock the car forward and rearward and have the wheels only move about an inch as the transmission is in park...   it will try to twist the engine and transmission...
