Here's what's up with my 2001 XK8:

For a few years I have noticed that when i put the selector in"D", there is sometimes about a half second pause afterwhich things connect and off I go.

Today, I got my first "Transmission Fault". I had to give it a bit more gas because the transmission stated to slip. I did get to my destination and experienced no problems on the way back.

When this all started, I had my Jag mechanic check the ATF level (no stick) and he said it was fine.

So fixing this could cost perhaps a filter and ATF all the way to a rebuild.

Any guesses on what is wrong? Advice? Recommendations?

Thanks!

 

I'm an absolute novice at this but, all the advice I have seen suggests having a shop put a Transgo or other upgraded main pressure valve in your transmission to replace the existing, weaker original one that leads to troubles with the clutch drums. I had that done on my low mileage '03 VDP as a preventive measure when I bought it last year. Cost me about $900 to have a reputable local transmission shop change fluid, filter and replace the valve.

Again, I don't profess to be any kind of expert but I've read a boatload on the subject and used that info to guide my actions.

 

I think the A drum is cracked and needs to be replaced with the updated version.

You may get more responses by posting on the XK8 (X100) forum.

 

Does the transmission need to be removed from the vehicle to replace the drum?

( I heard this same diagnosis from a local Jag authority)

 

And one more question. Does the North American 2001 Jaguar XK8 use the ZF5HP24 transmission? The reason I ask is that the ZF documentation shows that 1999 was the last year for the ZF5HP24 in the XK8. If that is so, what transmission do I have in there?

Thanks!

 

The 4.2 L series beginning in 2003 has the 6HP26. All earlier cars had the 5HP24. The transmission definitely has to come out, and whether to rebuild or replace has been discussed for years. Use the search and do some studying. A competent transmission shop or foreign car specialist would be a better choice than the dealer, who may not even want to work on your "old" car.

 

Dave, this is a XJ group. I think you have an XK.
