X Type 2.2D Auto transmission slip

Recommended Posts

Hi, I am new to the forum and to Jag ownership. I bought my 58 reg X Type 2.2D last August and it's been fine so far.  Recently I have noticed a couple of instances of transmission slip which have given me cause for concern.  Last auto I had that slipped was a 1979 Granada with a leaky box so I naturally considered low ATF. However, I am given to understand that the Jag box is 'sealed for life' which means messing about in the depths of the engine with a turkey baster in order to top up the fluid.  A local garage will be looking at it and they have suggested it might just need a software update (or the top up) but it could be a replacement gearbox.  The car only has 115k on the clock and had 2 previous owners about whom I know nothing.  It doesn't look or feel like a hard used car.  Since I've had it it's been used mainly for short local runs and the slipping manifested itself on a cold morning.  If anyone has any insight to offer I would be grateful.

Hi.

Manufacturers say there gearboxes are sealed for life that's not exactly true, the 6 speed auto is an Asin Warner gearbox and the only way to change the Fluid is to take it to an Auto Transmissions Company where they will attach a Hot Flushing Machine with 2 hoses and remove the old fluid and replace with new. I was told that there are paper discs in the gearbox and condensation can distort them , i had my x type auto fluid changed in July 2014 with 21,000 miles on it. And was told that the Fluid should be changed about every 4 or 5 year's and my car is just coming up too 39,000 miles so i might get it done come July as I think the Fluid change is more to do with age rather than mileage done i think the price was round about £153 pounds.

I'm afraid i can't help you with the slipping problem, but another member may be able to help .

By the way you need a Low Ash C1 Oil this is the number ( WSS M2C 934B ) and this number is not mentioned in the Handbook , and only use 5-5 litres instead off 6 litres and we recommend to use genuine jaguar oil and fuel filters .

The diesel engines now a days don't like a lot off short journeys and if you do we advice to go on a long journey every 3 or 4 weeks and give it an Italian tune and don't always keep the engine revs below 2000, diesel engines need to be worked .

hi

If its the zf 6hp26, 6 speed, 6 speed gearbox goes to 2 to 5 on the left side of j-gate,

though sealed for life still needs servicing, if its done 115k it well overdue

if it low on oil it can make it slip and even do damage

theres kits on ebay, for the service parts, which include oil, filter, new pins for filter and a mechatronics sleeve which are prone to leak

only use genuine zf parts and especially zf oil lifeguard 6, if not can cause lots of issues at a later date

also if it done at jaguar or a descent jaguar indy, they check the gearbox software is up to date, they clear adaptations and do a learn cycle, these alone are known to fix most of the issues

but yours sounds like its low on oil, with it slipping, torque converter relies on oil and if it low could be the issue

cheers

Joe

I've never heard off a zf auto gearbox being fitted to a facelift 2008/09 model x type as I said it will probably be a Asin Warner auto gearbox and there is know filter too change when the Fluid is being changed and any filter that is in the gearbox can only be changed if the gearbox is dismantled for a repair , that's what i'm led to believe.

Regards Tom.

hi

not sure what gearboxes the x-type had

most had ford gearboxes 5R55N was a 5 speed, but thought later ones were ZF but maybe wrong

if its the Ford unit there very easy to service and low oil again would cause it to slip

cheers

Thanks for advice everyone. Since the warmer mornings this week the slipping has abated. The car will be checked out on Thursday by some electronics wunderkind on the local industrial estate so I wait with bated breath for his conclusions.

hi

also worth mentioning is some auto gearboxes allow more torque converter slip in colder weather

this it get the gearbox up to a operating temperature quicker

does it stop once the car is warm and up to normal running temp

cheers

Thanks for advice everyone. I have been told that there's nothing wrong with the transmission and it hasn't played up since. Apparently the EGR was knackered and this was causing false code readings. After much messing about I finally got the correct part fitted and car seems to be running well. I have been advised to get a carbon clean and to give the car at least one decent run a month. Happy to do this as it's a really nice drive.

I was recommended a process called Tetraclean.  On checking the interweb I think the mechanic meant Terraclean since Tetraclean appears to be a laundry product. The Terraclean website is here https://www.terraclean.co.uk/ . I haven't used it yet so no idea if it's any good but the guys who worked on my car seemed impressed.
