2004 XJ8
2004 XJ8
Aloha, I’m new to this site and I hope I can Find out what to do.
I just became the owner of a Noce white XJ8 with 55,000
miles on it. It was given to me. I know the car had been sitting in the garage for a while because the original owners son threw it into park without coming to a complete stop.
Now, ,I’ve had the car for two weeks now and found that the jgate shifter needed to be changed and I did so.
now everything on the shifter lights up when a gear is selected.
But when I put it into reverse....
nothing
neutral - wheels spins in forward direction .
drive. - nothing
and same for the other gears.
I do hear a small clicking noise.
Is this a simple fix or do I need to switch out the transmission.
Anyone,
HELP me please.

Do you get the fault light come on, and a message about the transmission ? If so, get the stored fault codes read.
If you have no drive at all back or forward it does sound like something was seriously damaged by this rather reckless youth. However, it could be something fairly simple. Either way you are going to have to spend a bit of money. Check the bolts holding the change cables where they go into the transmission. These can work loose, and even drop out.

but it would not start in the Park position. In fact., When I closed the door and turned the key , All the lights in the dash come on with the chimes, the doors lock and the front /rear sensors are active . So that’s how I narrowed it down to the shifter. I have access to a xj8 same year and got the shifter put it in. It started right up with the key. No fault lights or messages.
The car I got the shifter from is complete and I was given access to it for parts. I also have a 2009 XF That has been beaten with a baseball bat up in my yard . That one has the complete motor and transmission.
of which is 2009 XF supercharged. So parts are already covered . I’m just want to exhaust all the possibilities before I go and start switching them out.
thank you for your quick response.

+1 checking the shifter cable bracket at the transmission - these bolts are a known common problem as they do work loose and sometimes fall out as Fraser said.
As for the clicking noise, what sort of clicking? Does it sound like its from the trans?
Possible there might be some damage done to the parking pawl mechanism, but this will require some disassembly of the transmission..... pan, valve body, etc. to gain access. This will be easier to do than swapping around entire trans.

I think I’ll require a diagram of the inner workings of the transmission. Just so you know what I’m looking for.
the clicking sound just started after I went though the gears after changing the shifter. And not like one time. It was like I was letting it run so I could put the fill hole and see how long it takes for the fluid comes out as I drop the backend of the car down..
I have another question if you don’t mind.
Where is the fill hole on this year transmission?
on the right side of the transmission.
or the back end mere the driveshaft?

The fill plug is on the right hand side next to the exhaust pipe. Because of the small clearance between the two you will need something short, like an 8mm bit with a box end wrench to turn it.

I appreciate your help.

Most sellers will downplay the damage they did to the car. After you check the linkages it may be necessary to drop the transmission pan and see if there are any metal bits or pieces in it. On an old automatic throwing it in park while moving could break off the parking pawl. That may or may not also create more broken items in the transmission. Honestly though setting up a swapped shifter can be difficult on any car and I imagine the Jaguar gods only made it worse on these lovely creations. Was there a specific procedure you followed or trial and error. I have not researched it.
Good luck.
Good luck.
I put the car down on it wheels for now and started it up and there was no noise or the clicking noise is not present anymore.
But I will remove the pan to check for parts in the fluid.
thanks again everyone for your help and have a great work week. Till next weekend

I'm glad it sounds better. Do some research on changing the transmission fluid before you drop the pan. That way you can have the gasket, filter and enough fluid to change it. Plus you may need something to fill it. From what I've read it is a little bit of a pain to fill and check. At least it is running so you can get it hot to check the level when you are done. I would try to sort out the shift issue to make sure you can get it into forward and reverse before I changed the fluid if it is quiet. The new shifter could just not be adjusted right.

I forgot to ask if my has a neutral safety switch.
I do where is the location.

What do you mean by a "safety switch" ? Is it - On my 2007 car, I can select R or D from N without having my foot on the brake pedal, unlike wife's New Beetle where you must press the brake pedal to select from P or N ?

In my review of the Powertrain Handbood I have come to the conclusion that Jaguar uses the "Transmission selector lever interlock solenoid" as a safety switch. I can't find anything else like what is used on my older cars. Too bad. I was kind of hoping one of my little problem might be a bad neutral safeyf switch.
The Handbook has the procedure for setting the J gate which is where I found the reference to the solenoid.

The gearshift interlock is simply to prevent the transmission selector from being moved without having your foot on the brake. It doesn't lock the transmission, only the selector.
In the ZF, the transmission is locked by the Parking Lock Disc which is engaged when the selector is moved to Park. Selecting Park with a moving vehicle can break this or the spring on the shaft.

There's several selectors and rotary switches listed for the X305. Just because they look the same doesn't necessarily mean compatability.

Anyway, I followed the advice and drain the fluid and it smells burnt. So out of curiosity I pulled the pan filter and yes there is shavings inside.
I’m planning to pull the transmission out on Saturday.
it looks fairly easy to do. Then on Sunday I wanna go to the donor transmission and Pull it.

Before you do read Slowpoke's experience here:

ie Put the old TCM in the replacement g'box before you fit it, then the Jag will not 'know". LOL
Good Luck

Sorry to hear about the extent of your trans damage.
Glad you have a replacement on hand, makes it a lot easier to take. 
Have a couple XJ8's myself, 04, & 07, you should be very happy when done, both mine are great cars.
Good luck with your project.
