When the fluid no longer look red. Transmission Fluid normally doesn't have to be changed that often.
For a manual transmission, maybe after 100K. The manual transmission fluid is thicker and hardly ever breaks down. Unless the gears are clashing, etc.
But for an automatic transmission: that would depend on how you drive you vehicle. A good idea for a transmission fluid change would be every 3rd to 4th motor oil change.
The transmission fluid is completely different from motor oil, but will eventually wear out.
I say a fluid and filter change. It is usually a bad idea to get a transmission flush if the transmission is doing good, so far.
you change the manual transmission fluid in a '99 cavalier simply by removing the transmission drain plug and allowing all the fluid to drain then replace the plug and refill with Syncromesh transmission fluid(that is the fluid recommended by Chevy for use in your transmission) It should take 2 quarts.
Why? There is no need to change the manual transmission fluid in a 2 year old vehicle.
Yes. I check all fluids at each oil change
Should be a drain plug at bottom of transmission Should be a fill plug at side of transmission - fill to this level
dependin on certain cars but i will always change every 45000 miles
Should be a drain plug at the bottom of transmission and a fill plug at the side
Follow the recommendation in your owner's manual. Or change it every 36,000 miles unless it is a sealed for life transmission.
poop
Yes, it should be changed as outlined in your owners manual. If you have no manual change them both every 75,000 miles.
you dont put transmission fluid in a manual transmission. you need gear oil, and it should be done by a transmission shop
Consult the maintenance section of the owners manual.
A manual transmission does not typically use [automatic] transmission fluid, or "ATF." As it is just a gearbox, it is usually filled with "gear lube" oil formulated for the task. Whatever type of lubricant is specified by the transmission manufacturer, it should be changed occasionally due to oxidation breakdown with heat and time. Consult the owner's manual for the proper fluid and interval. It should be much longer than an automatic transmission.
