CAN AN IDLER PULLEY BELT TENSIONER CAUSE PROBLEMS WITH TRANSMISSION

Asked by Oct 06, 2015 at 05:56 PM about the 2001 Jeep Grand Cherokee

Question type: Maintenance & Repair

MY 2001 JEEP WILL NOT GO INTO REVERSE.  I JUST HAD TO
REPLACE MY IDLER PULLEY AND BELT TENSIONER RECENTLY,
WHICH WAS GOOD BECAUSE WE FOUND OUT IT TOOK CARE OF
HAVING TO BUT A GALLON OF ANTIFREEZE EACH WEEK. TODAY THE
JEEP STOPPED GOING INTO REVERSE AND I NOTICED THE BELT
TENSIONER HAS CRACKED SOME.  COULD THAT BE THE PROBLEM
WITH NOT GOING INTO REVERSE TODAY

The idler and belt tensioner has nothing to do with the transmission. You said you were loosing antifreeze? Might be the water pump has failed since you mentioned the tensioner is cracked again.
