Answer
HI CARTER CLAY, WELL WITHOUT HEARING THIS IT IS HARD TO SAY BUT A FEW THINGS COME TO MIND.
THE BEST CASE IS THE TRANS FILTER IS PLUGGING UP..HAVE YOU EVER DRAINED THE TRANS OIL AND INSTALLED AND NEW FILTER. IF NOT, I WOULD SUGGEST DOING SO..THE LAST THING I CAN THINK OF IS THE FRONT PUMP,[[BEHIND THE TORQUE CONVERTOR]] THEY WILL WHINE WHEN GOING BAD OR WHEN OIL STARVED.LIKE FROM A [DIRTY FILTER]..IF YOU NEED MORE INFO GET BACK IN TOUCH WITH ME.. I HOPE THIS HELPS YOU..PLEASE WHEN YOU LEAVE THIS SITE WOULD YOU RATE MY ANSWER. THANK YOU VERY MUCH,,,TOM.
