If it's a manual transmission car it's the brake fluid. It uses a hydraulic clutch which uses the brake fluid to lubricate. On my 2003 it's on the right side at the rear of the engine compartment.
T-IV for an automatic.
Have ALL the fluid drained and replaced with the exact fluid that Saturn recommends. Use not other fluid. Do not flush.
It don't have 1. You must remove the transmission pan to drain the fluid.
If you are who I think you are from Fresno. Contact me. I'm hear to help Veena.

To check the transmission fluid in a 2004 Saturn Vue, first ensure the vehicle is on a level surface and the engine is running. Locate the transmission dipstick, usually found near the back of the engine bay, and remove it. Wipe it clean, reinsert it fully, then remove it again to check the fluid level; it should be within the marked range. If necessary, add the appropriate type of transmission fluid through the dipstick tube.

To add transmission fluid to a 2004 Saturn Vue, locate the transmission fluid dipstick, which is typically near the back of the engine bay. With the engine running and warmed up, remove the dipstick, wipe it clean, then reinsert it to check the fluid level. If it's low, use a funnel to add the appropriate type of transmission fluid through the dipstick tube until it reaches the correct level. Be careful not to overfill, and always consult your owner’s manual for specific fluid specifications.

It's essential to use the recommended CVT fluid for optimal performance. Always check the owner's manual for specific details, as fluid capacity may vary slightly based on the transmission type and any additional components.
