Where do you put transmission fluid in a 1991 subaru legacy?

To add Transmission Fluid to a 1991 Subaru Legacy, locate the transmission dipstick, which is usually found near the back of the engine bay, near the firewall. Remove the dipstick, wipe it clean, reinsert it, and then remove it again to check the fluid level. To add fluid, use a funnel to pour the appropriate type of transmission fluid into the dipstick tube. Always check the owner's manual for the correct fluid type and capacity.
