could anyone please give me some advice on the following issue,i had my gearbox rebuilt in the range rover l322 vogue auto 2003 plate about 5 months ago,but unfortunately its again failed i took it back to the gearbox specialists who say its due to the oil cooler feed pipe blowing off causing it to loose oil,the oil cooler and both pipes was replaced when the box was rebuilt,is this a common issue ? what would cause the pipe to blow off ? your info will be much appreciated,regards Lee
