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 sh!t. 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

spread the wealth guy's .
this should definitely be in the s type stickies as well !!!

thanks

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 fixed my ZF restricted mode on my 2005 s-type 3.0 by changing the plugs (you have to remove the intake manifold to do the right side), cleaning the throttle body, new battery, clearing the codes. Thanks to this forum I found out those were potential causes, and changing those things removed the restricted mode. My car is fixed and runs great! Very happy!

Good article, thank you for this.

If I may, I might like to visit with you on this.

Link appears to be dead, or is it just me? If it is dead, why do the mods leave it up?

Here's two that do work https://www.bavlogic.com/?p=3738

Aren't mods wonderful? :icon_beerchug:

Just wanted to add that i got all kinds of gearbox faults due to a leak in the intake pipe (after air massflow meter). I thought i had a really bad transmission as it was behaving, but everything went away when i fixed the leak in the intake pipe. This was on an STR 2002.
Might be worth to take a look at that if your transmission is behaving strangly…

Lots of times an ENGINE fault upsets the TRANS.
