Usually you should change your Transmission Fluid after 60,000 miles, but to be safe you should check it after 30,000 miles and if it looks like it is low I would add some fluid.
You need to get the trans fluid changed immediatley
Yes.
Of course, it does. The transmission fluid must be changed each 60 000 miles or less. If you drive in severe conditions (mountains, snow and so on) regularly you have to changed it even more often.
It is advisable that you check with your local mechanic as to when you should get your transmission fluid changed in your car. Ideally, it should be changed every 3 years or so if the car is driven aggressively.
the automatic transmission don't need the fluid to be changed never if you change the fluid with a new one you going to lost your transmission
You need to check the fluid level.
My advice would be to have the transmission fluid and filter changed. If that does not correct the problem you need to have the transmission rebuilt by a professional.
Yes! you should flush your transmission fluid at least two or three times a year or when you chanfe your fluid and filter in the tranny.
Volvo says that their automatic transmission has a lifetime fluid that does not need to be changed. On the other hand, most experts recommend replacing the transmission fluid every 30,000 miles to extend transmission life and prevent premature transmission failure.
Find another shop. Most manual transmissions oil need to be changed only after 50,000 to 100,000 miles. If you have no shifting problems leave it alone.
If it is automatic you have problems. If it is standard you still have problems. Put some transmission fluid in it then if it still "slams" you need a new transmission. ---------- The transmission is not slamming itself yet you are experiencing the gear drop in rather hard inside the casing. Check your transmission fluid level and make sure its full. Also check the consistency and color of the fluid to see if it needs to be changed (filter also will need to changed). I had an old Pontiac do this very thing and it was because it was extremely low on trans fluid. - jedgell233
I recommend transmission service every 36,000 miles.
