My 2001 trooper went from 19 miles to the gallon to 10, over night. Took it in for a slipping feeling and the first place told me transmision oil is burnt. Told me I need a new catalytic converter and repairs will be $1200.00 plus. My mpg have dropped in 2 days. I'm a girl and do not want to be taken advantage of again as Firestone just charged me $382.00 for a tune up, spark plug change, and fuel flush and neglected to tell me about the other repairs that it needed. what do you think?

Well, i must admit, that transmission fluid does not turn lrown overnight and should have been one of the things that firestone should have checked.......not to mention the cat converter....

my advice is it does sound like your transmission will require an overhaul, as inside the transmission there are things called bands which are friciton material (similar to brake pad material) and they surround the drum...and when this friction material comes off (wears) it gets absorbed by the oil and turns it from red to brown, and if you smelt it, it would smell like burnt toast.,....bad smell.....

due to the nature and cost of the job, I would look around for at least 2 quotes and see what you come up with, i would not necessarily go with the cheapest but with the person who treats you the right way and is upfront with everything....

It was good that you cam on here and asked us to provide you with info...if there is anything else we can do, please do not hesitate ....
