Schizophrenic Transmission
 Transmission shift points unpredictable, hangs in lower gears sometimes, have to upshift manually.  Also, run flat tires are awful.  Problem with parking brake locking up will not release by electronic control, had to release by manual method in truck compartment.  ROYAL PAIN in the rain this morning.  Good luck.
