should I worry about a trans in a 96 Sable 80,000 miles
Are you going to keep asking the same question till you get the answer you want? Nah, don't worry, drive it like you stole it!
You shouldn't have too if it was taken care of. Just change the transmission filter and fluid, but do not get a transmission flush. Then you will have grief down the road.
Didn't know that Tom....
Taurus, Sable yes you should worry, have it serviced and add some Lube Guard for Ford transmissions and hope for the best.
