How do you check the oil in a jaguar xj8 automatic gearbox?

To check the oil in a Jaguar XJ8 automatic gearbox, first ensure the vehicle is on a level surface and warm the engine to operating temperature. With the engine running, locate the transmission dipstick, typically found near the rear of the engine bay. Remove the dipstick, wipe it clean, reinsert it fully, and then remove it again to check the oil level; it should be between the marked minimum and maximum levels. If necessary, add the appropriate automatic Transmission Fluid through the dipstick tube.
