The 2004 Jaguar XJ8 transmission fluid type is Valvoline MaxLife Full Synthetic. The transmission fluid needs to be replaced every 30,000 to 60,000 miles. Along with fluid changes, terrible sounds will come from the transmission. Old transmission fluid will be awful to the ear. A worn out torque converter will cause a headache. The transmission is one of the most crucial parts of the vehicle. You will come into issues at some point. The gears can become stuck. There could be jerking. Hard shifts may arise and that is no good. You might experience shudders. Delayed shifts will cause acceleration problems. The transmission could slip. If the transmission fluid leaks, that needs to be patched quickly.
