1999 Jaguar XJ8 Repair Question
1999 Jaguar XJ8 transmission
1999 Jaguar XJ8 V8 Two Wheel Drive Automatic 80,000 miles
I changed the oil in the jag and now the trans is slipping and making some noise when it shifts. When I drained the oil there was a bolt to what I thought was the oil pan that need an allen wrench to remove. Never seen that before. Oil came out ( not trans fluid) and now the problem. When I replace the oil, ( it takes 6.9 quarts) it showed over full just after 5 quarts. Did I some how empty the trans fluid instead of oil? Is there such a thing as trans oil? This car never needs to have trans flid replaced according to the manual. Thanks for any help Bryan firstname.lastname@example.org
It does sound like yo may have drained the trans fluid (ATF) .. you need to check the trans fluid level is correct !!

Park vehicle on level ground. Apply parking brake. Wait at least 2 minutes. Ensure transmission fluid temperature is less than 86 °F (30 °C). Start engine and verify idle speed is 600-750 RPM. If idle speed is not correct, repair as necessary.
Move gear selector from Park to Drive to Reverse and back to Park. Raise and support vehicle. Remove fluid filler/level side plug. Fluid level should be level with bottom of filler plug hole and flow of fluid should be a trickle after about one minute. Top off as necessary.
Top off using a syringe dedicated to transmission fluid only (not used for any other type of oil or fluids). Ensure transmission fluid temperature is less than 122 °F (50 °C). Inject transmission fluid into filler side plug until it overflows from plug opening. Wait for at least one minute until flow of fluid is reduced to a trickle.
Install fluid filler/level side plug and tighten to specification. See TORQUE SPECIFICATIONS . Check for leaks and clean up spilled fluid.
