Default ZF gearbox faults, root causes & Troubleshooting

With ref to Jim's request for stickies I think

that this should be included:

Agreed and should be a sticky in the X150 forum as well. Thanks for posting.

Interestingly, there is a link for testing out the MOST BUS network too which would also benefit X150 owners.

This should also be added if it isn't already.

Thought I could add a comment here on what I suffered

04 xj8 n/a

(She) cat threw the abs light

10 miles later , cat went into transmission gear faults and basically wouldn't shift out of second gear . Felt incredibly a bit like the trans was toast clanks and squeals and all kinda ****. So I replaced the driver rear abs sensor with a rock auto part and boom , all was perfect again


transmission didn't like what the abs sensor wasn't saying and acted up for it

Last week a similar series of events happened to my 2008 XJR. Trip #1 ABS fault & 20 miles home. Trip #2 ck engine light on start, after 2nd shopping stop 2nd, neutral, repeat, repeat, gearbox fault and 10 miles home in 2nd. Car has been at dealer for 3 1/2 days. Haven't heard anything.

I did get dreaded transmission codes as well as body module ones one day. Threw about 6 codes in total as I recall. Turned out to be a broken wire in the top of the left front shock on my 01' xkr.

As discussed in the thread - "What's the mileage on your ZF 6HP gearbox ???" - posted by Supersprint - here is a link to the Jaguar adaption procedure (TSB JTB00145) - which can be printed off and shown to your Jaguar dealer.

http://www.justanswer.com/uploads/cr...00145NAS11.pdf

I will be looking into having this done on my XK8 in order to help eliminate the occasional harsh gear change problem. I'll let you know how I get on.

I have heard about this adaptation procedure. I am still getting an occasional squawk when the car downshifts from 6 to 5 and sometimes accompanied by a 5/6 gear ratio error message despite twice doing a fluid filter change. Only happens during a gentle downshift from 6 to 5. Not during a hard one.
Think this might help with that issue?
No harsh shifting issues.

What ATF did you utilize when you did your pan drop and fluid refresh?

Sorry but I have no idea....this adaption procedure is all new to me and seems to be addressing the harsh shift issue...so I don't know if it will help your transmission.

Hey Jon89
I did it once with the Ford Mercon that they used in their ZF cars and did it again with Lifeguard 6.
40 degrees C and a slow drain out of the filler plug when I closed it up

So the gearbox fried on my 1997 XK8, mechanic told me it needed to be replaced. I didn't have the cash for a rebuilt one so I bought a used one and had it professionally installed.

It worked well to start but I noticed when I shifted from reverse to drive without fully stopping, I got the dreaded transmission fault. Turning the car off and then on again returned it to normal the first time, but the second time I had to let the car sit for a few days before it decided to magically work again. It took about three times for me to realize the bad shift was what triggered it so I was careful when shifting from then on out.

However, yesterday it faulted twice: once when I was driving normally in city traffic, and then again when stopped at idle in a parking lot. I'm worried that this used transmission that has been in for 9 months with less than 1000 miles is going to go up again.

So, any ideas? I'll add that I also had the car in to diagnose some strange whines and they suggested it was likely coming from the transmission.

HELP! I love my car but it's frustrating to constantly worry it's going to die on me.

Glad I joined this forum. I'm new to the car, a 99 XK8. I'm working with a shop and they have it down to 5 codes (from about 15). The most serious they say are the check engine light, a phantom misfire code and an ABS fail code.

The trans still won't engage except in a high gear. No noises, just no power to the wheels. The engine seems to work fine. They are first concentrating on the misfire code.

The dealer had said one of the wheel speed senors was broken and the module was not reading properly.

Could the ABS situation may be more related to this issue than the misfire code? Any thoughts would be appreciated.

Yes

Suggest you post this as a new thread in the 'Normal threads' rather than here in the stickies, or ask one of our tireless mods to move it for you.

Good luck,
Mike
