OSSS Output Shaft Speed Sensor. Located on the tailshaft of the tranny
(drvr side). About $28-35 new over the dealer counter.
You can try cleaning the one in there first. It has a magnetic end and
tends to attract debris. Its about a 5-10 minute job.
Jack the REAR of the truck up so the fluid goes forward in the tranny, and
not in you face when removing it ;-)
Undo plug, using a med/lrg adjustable, loosen and remove. Clean the end
with a rag, replace. Hand tighten, then just snug with the wrench. Reset
the PCM (disconnect the battery, turn ignition key to on).
If the lights come back, buy a new sensor.
Olznut's diagnosis is the usual first guess, but when the RWSS goes, the
speedo acts funny at low mph, and the shift points are usually normal.
