You do not need to change the transmission fluid in the Saturn vue. It is a sealed system and only needs to be replaced when the trans needs rebuilding.
how do I put transmission fluid in a Saturn vue
How do you check the transmission fluid on a 2003 Saturn vue
The transmission filter on a 2006 Saturn Vue is located inside the transmission, typically accessed by removing the transmission pan. To reach it, you'll need to drain the transmission fluid, remove the pan, and then take out the filter. It's advisable to consult the vehicle’s service manual for detailed instructions and safety precautions before attempting this task.
Transmission
Only the manual transmission Vue can be flat-towed.
To change the transmission filter on a 2003 Saturn Vue 2.2, first ensure the vehicle is safely lifted and supported. Drain the transmission fluid by removing the pan bolts, then carefully take off the transmission pan. Once the pan is removed, locate the filter, detach it from the transmission, and replace it with a new one. Reinstall the pan with a new gasket, refill the transmission with the appropriate fluid, and check for leaks.
There is no powersteering fluid. It is electronic.
it uses a Delco synthetic transmission fluid on the CVT 4 cylinder transmission and ATF on the V6
How much transmission to replace new?
no........
Yes and I would suggest the sooner the better, no later then 50,000 miles. If it is more then this you will need to do it twice. The first time is to flush it clean. You are looking at $150 - $300 to have this done. The transmission is weak on the Vue.
