As long as you keep the car, then keep chaging the fluid. Do not flush the transmission on a car with this many miles, just chage the fluid.
I recommend you have the A/T fluid changed every 36,000 miles.
No, changing the size of your rims and tires will not mess up your transmission. It will mess with your gas mileage and your speedometer though.
yes your transmission fluid should be changed and should be changed every 80,000kms
I know your problem is related to the transmission, due to the lock-up converter in the transmission. It's usually related to, or with, higher mileage vehicles with thinning transmission fluid and/or high mileage. Unfortunately, changing the transmission fluid on higher mileage cars can actually cause more damage sooner than not changing it. Wish I could help you out more since I own one of these cars myself and have the same problem. I'm still trying to figure out how to change the headlights!
I would change it. A lot of people neglect on changing gear oil. Most manufacturers recommend changing it, mileage varies, check your owners manual.
You cannot know by looking at it. This is why the belt is changed at a set mileage as listed in your owners manual. You change it when your vehicle reaches that mileage. You did not list make, model, & year so I cannot tell you the mileage at which it should be changed. Warning: If your engine is an interference engine and the belt breaks you will have serious engine damage.
There is no mileage where one "has" to change the transmission fluid or filter. It is your car and you can do with it as you wish. The warranty manual for my 2000 Forester recommends changing the fluid every 15,000 miles when used under severe conditions. I recommend changing ATF yearly and you shouldn't need to change the filter unless it has been damaged. It is as easy as changing the engine oil, so why not do a little preventive maintenance? --Ken
It will effect the accuracy of the speedometer and odometer, effect the transmission shift points, effect the fuel mileage, effect the brake horse power,
no
your owners manual will give you the recommended mileage as to when it should be changed, usually between 30 and 50,000 miles.
The timing chain or belt on a 1999 Pontiac Firebird at 98,700 miles does not need to be changed unless it is showing signs of wear or breaks. There is an inspection plate that can be removed to check this. As far as changing other things at this mileage, consider changing the filter and fluid in the transmission. The engine oil should be changed every 3,000 to 5,000 miles.
