Default sc speedometer wows

1992 SC 400. 166k

two weeks ago noticed cruise control would not grab steady at speed 45mph.
last week speedometer needle is bouncing all around at speeds greater than 45mph. at 70 + on the interstate really bouncing around.
have done some research, my mechanic says he has never heard of a speedometer motor, and lexus wants $244. for the sensor on the transmission.
had my needles re=lit a year ago too.

anyone know where to start? i know the two malfunctions are different, yet ?

changed out cruise control motor, still does not function.

odometer does not register at speeds greater the 65mph or so.


changed the speedo sensor, needle works fine as-well as cruise control

the end
