The six speed ZF is known for leaking at the sleeve where the wire harness goes thru the case. Many threads on it. Cheap to fix as the updated sleeve

 

Ok so What I meant was where do I get the o ring for the Plug that goes into the sleeve? Seems to me that it may be a source of leak? Or can I wing it and put fitting O ring on that will be tighter fit.

 

If you can access eBay then it is simple: just search for ZF6HP replacement parts. You will find listings for the correct pan/filter, for the bolts to secure the pan, and for the mechatronic sleeve and gaskets. I have done this - very easy but the ZF for Jaguar may be slightly different in the pan shape than for the same transmission in a BMW or other car - so if the website permits, specify that this is for a Jaguar.

I am looking for source for o ring for plug ..

 

Welcome to the forum John,

I've moved your question from X150 to X100 forum. This is the place to post technical questions about your model.

Thanks I noticed error could not fix John

 

You might have to take a step back for a minute.

First, confirm there is a leak from there to begin with. Best is to do a good cleaning of the area (contact cleaner or brake cleaner). Then drive around for a while. Then check the area again for fresh evidence of the leak. You are right that that connector sleeve is known to leak on occasion.

You can of course replace just the sleeve with a new one (I believe the new ones have a newer design), but the problem is that you have to do a bit of work to get to it, which brings the discussion into the larger context of transmission maintenance. The issue is that to remove the sleeve, you have to unlock it from the bottom, which means the fluid has to be drained and the pan/filter removed.

The short of it is that if you are unsure of the maintenance history of the car, you need to start looking into a new (plastic) pan and (built-in) filter, new bolts as well as the sleeve and fluid. There are several options ranging from genuine ZF parts for some money all the way to cheap after market parts on eBay. Same for the fluid, choices are between Jaguar, ZF LifeGuard 6 and Mercon SP.

Be sure to pay attention to the refill procedure (it is temperature based). Once you get this all sorted out, plan to do another drain/refill a bit later down the line to flush out even more of the leftover original fluid.

Best of luck, keep us posted.

 

Looks like I have the same question as Jaglearner did. I believe he was asking about the o-ring on the plug connector show in his picture, NOT the mechatronic sleeve. This connector and its oring plug INTO the mechatronic sleeve, then locks down with the tab ring.

 

Why do you think you need a new one? If there is evidence of a fluid leak in that area, the o-rings on the sleeve are the problem. It can manifest itself with fluid into the plug. IOW, if the inside of the plug has fluid in it, the culprits are the sleeve o-ring seals.

I believe the orange ribbed seal in the picture above is to prevent rain water or dust from contaminating the plug. Needing a new seal as pictured above is not common. You might need to contact one of the more advanced transmission parts companies like CTSC or Sonnax.

Best of luck, keep us posted.

 

Thank you for your response. The mechatronic sleeve is definitely past due and so there was some oil on the plug itself. I wasn't sure if that was a symptom of bad sleeve seals by itself or maybe the plug seal was weak as well. It does appear to be uncommon to replace that plug seal as I couldn't find a single instance of anyone doing so. However, I did find a BMW part number for the entire plug and locking ring: 12527503442. So I suppose you could just steal the o-ring from the new part if necessary.

This is on a 07 Range Rover, btw, not the XJ in my signature.
