A trans can fail with low mileage or high mileage. With only 65,000
miles in 9 years how many times has the transmission oil been changed?
Not changing the oil enough or at all because the car has such low
mileage can be harmful, My mom has a 91 Cadillac Brougham with 49,000
miles and I think the trans oil was only changed one time in 13 years of
ownership. Hardly any miles yes, but lot of age on the car. The car is
only used 100 miles a month - if that..
One important quesion - Are any Teenagers driving your car ? This can
shorten the life of a transmission.
When I had my trans rebuilt in 2001 with 192,000 miles the next car they
did after mine was a 96 Seville. ( $3600 job ) One reason the cost is so
high is virtually everything under the hood has to be disconnected or
removed so the engine & trans can be lowered from the vehicle. My Trans
man said the Seville trans remove & replace job is a total of 16 hours
labor, just for R & R. Rebuilding is the easy part, its the removal &
installation thats the problem.
