Where do you add the transmission fluid to a 2001 Chevy silverado its an automatic and for some reason i cannot find plug?

The 2001 Chevy Silverado automatic transmission doesn't have a dipstick to check or add transmission fluid like older cars. Instead, it has a sealed transmission system. You do not add transmission fluid through a plug.

Adding transmission fluid to this type of transmission is typically only done by a mechanic or using specialized equipment. Trying to add fluid yourself is likely to cause damage.

If you suspect low transmission fluid, or are experiencing transmission problems, take your Silverado to a qualified mechanic immediately. They have the correct tools and procedures to diagnose and address the issue properly. Improper fluid levels can seriously damage the transmission.
