Just been told by Jaguar that my 51 x-type 2.5 litre auto needs a new gearbox for £3740!! I couldn't believe this. Can anyone help with the following symptom?

Car runs fine and accelerates, however, when a decent amount of acceleration is applied say at around 40mph the engine revs rise but the gearbox appears to slip, if you take your foot off and slow down and it's fine. Seems to go through the gears fine and I have taken it up to 60 no problem suggesting the gears can all be selected. There was a note on the cars computer that there was 'a gearbox fault' a couple of days ago but this has now gone - is this a software error then?

The service centre said their computer suggested the box was knackered and was not selecting gears. They also noted the box oil smelt 'burnt. (Apparently it is never checked in a Jag service is this true? I can’t believe it? Car was only serviced 2 months ago)

The car has only done 40,000 miles from new I have owned it all this time and it has a full Jag service history. To say I am peeved is an understatement since the car can only be worth a few grand more than the box anyway.

Anyone else had a similar problem on their box that was fixed rather than replacing the whole box!! I know that the gearbox is a complicated item with many components surely one of these may have failed? I am based in south Essex anyone know of a good gearbox specialist around here?

All advice gratefully received.

Firstly I would check the manual to see how to check the level in the gearbox.

On my Merc I take it for a drive for about 15 mins to get it up to temp, then with the engine still running check the level.

When my level was very low I had the same symptoms as you but only from cold, it's worth a check at least.

Dave!

A Jag dealers main interest is getting cars through the workshop and hitting the till.
A decent auto box specialists main interest is hundreds of little bits scattered across the bench and putting them all back where they belong. The ones I have met place making money way down on the priority list.
Can't help with names as I'm not in the area. If the PH collective don't come up with a name go to some local small garages and ask where they would send an auto box. That's how I found my local guy. You may also find an independent Jag specialist who can help.

i think you will find that they said that the tranmission oil smelt burnt NOT the engine oil - completely different things.
Burnt oil is a sympton of a knackered (slipping) clutch in the box, so it needs repairing.

Oil that is frothy will also cause slip, and the root cause of this is an overfill.

Before you go changing the transmission, have the oil changed and then filled. Have the dealer put considerable effort into setting the oil level right. It sounds easy but a lot of trained mechanics fail miserably at this.

Do this, drive the car gently and you may well recover function, given the cost of a transmission I think it is worth the effort.
