Jerky 3.9 V8 with little power

jackroadkill said:

Hi -

Got a problem with my Range Rover. It runs fine when out of gear but jerks quite heavily when in motion. It also seems to be lacking in power and there is an unpleasant clacking sound that happens when under power and going uphill. This sound seems to be coming from the left-hand side of the transmission or engine (from when sat inside the vehicle).

Does anybody have any idea what the problem could be?

Thanks,
JR
