STATOR TEMP READS HIGH ON SCAN TOOL. Buick Roadmaster 1995

THIS IS A MONTHLY SERVICE NEWSLETTER ARTICLE THIS INFORMATION IS NOT INTENDED TO BE A PUBLISHED BULLETIN

CONDITION: TRANSMISSION DATA LIST WITH TECH 2 SHOWS STATOR TEMP AS HIGH. THIS IS INTERPRETED AS HOT CONDITION OR GROUNDED CKT, AS DEFINED IN THE SERVICE MANUAL. STATOR TEMP DATA WILL REMAIN HIGH, WHEN SENSOR WIRE IS DISCONNECTED FROM PCM.

CAUSE: TECH 2 TRANSMISSION DATA LIST READS THE A/T STATOR TEMP DATA AS CIRCUIT HIGH OR LOW, NOT TEMP HIGH OR LOW. ENGINE DATA LIST READS A/T STATOR TEMP AS TEMPERATURE NORMAL OR HIGH.

THIS IS CAUSING CONFUSION TO TECHS WHEN DIAGNOSING A/T SHIFT CONCERNS.

CORRECTION: WHEN DIAGNOSING A/T SHIFT CONCERNS, READ THE STATOR TEMP DATA AS CKT HIGH (OPEN) OR CKT LOW (GROUNDED) WHEN MONITORING WITH TECH 2 IN TRANSMISSION DATA LIST.
