Usually due to the wrong spec of oil being used. The same would be true if for instance you put plain old Dexron III in the Volvo...

Most cars now have sealed for life auto boxes, 'Life' is generally considered by the manufacturers as 100,000 miles. Many Jaguars fail at the 85-95K mark and many people start to have the harsh or jerky changes or even delay and slipping changes at the 80K mark. You might consider it prudent to change the ATF at 80K -100K mark even with no signs of deterioration in changing.
The available ATF's are either mineral or semi synthetic (whatever that is ?) with Amsoil doing a top of the range full synthetic which is detergent based. Any new fluid will be an improvement on worn out fluid, but if you have had or started to have auto box problems consider Amsoil as the detergents will strip out the varnishes and sludges that impair proper operation of both clutches and valves, an ATF that is not a detergent base cannot do this. A further consideration is that if towing Amsoil can take an additional 100 degrees of heat without deterioration, we believe its the best and you generally get what you pay for.
As always your car your choice.

I had the message Transmission Service Urgent and Transmission needs service, its an old car 93k miles on the clock.

Its the 4 speed auto 2.9 t6 awd.

I thought I may as well try the gear oil change I purchased 9 liters of Carlube Dexron 111 on ebay £41 pound.

I proceeded to remove protection tray from beneath the gradually removed all the 10mm bolts holding the sump being careful not to damage the gasket of course using few containers to catch the old oil which was dark brown and should be red.

I then cleaned the sump cover it had grey sludge also cleaned the inner parts of gearbox that I could get too I could see using tissue.
I then put it all back together and refilled using a funnel from the top very easy to get too using dip stick hole.

I then test drove and to my amazement all faults cleared hazard lights stay off and now runs perfect.

lucky me .

its not a full flush

hope it works for you

happy days its great when things work

pics attatched

Hi

Is this the same oil as JWS3309?

Only reason i ask is that i have the D5 version and have about 8 liters of mobil JWS3309 left.

My friend has a 2004 t6 2.9L and was wondering if he could use it for his XC90

I don't think so , the Carlube JWS3309 juice is designated ATF-U.

My 05 D5 now has 193,000 on the clock and has never had the ATF changed. Refurbed engine a year (20,000 miles) ago.

Delay on take off but otherwise tickertyboo. I know I'm living on borrowed time, but I've been told it'll do more harm then good changing it now....
