I CLEANED THROTLE BODY AND NO VIBRATION, BUT IT IDLES SLIGHTLY HIGHER AND AS I SLOW DOWN FROM 4O MPH I NOTICE LAST 2 GEARS DOWN SHIFTING MORE OBVIOUS WITH SLIGHT JERK FORWARD. BY THE WAY FIRST TRANNY FLUID SERVICE AND CHANGE AT 100, 000 MILES, I WISH I WOULD HAVE DONE IT SOONER TO THIS SO CALLED "SEALED NO MAITAINANCE TRANSMISSION"

ANY IDEAS IF THE NOTICEABLE BUT SMOOTH AUTOMATIC TRANSMISSION DOWN SHIFTING WITH A SLIGHT PULL FORWARD COULD BE THE START OF SOMETHING?

HOW DO YOU KNOW WHEN TRANNY IS GOING OUT, WHAT SYMPTOMS BESIDED NOT BEING ABLE TO PUT IT INTO GEAR?
