Does anyone know whether the XJR (X308) transmission fill plug is the same size as the X350 transmission fill plug?

The reason I am asking is that a transmission dipstick kit is available for the X308 and I am wondering if I could use it on my car.

 

Not the same tranny. Its not an unusual question, but no, doesn't work.

 

Where did you see the dipstick? I could investigate to see if they make one for the x350 as the trans is used in several vehicles.

 

Jaguar Transmission Dipstick Tool.

Look at the above link Sean W.

Someone in Jaguarforums installed it recently on his pre 2003 XJ. Thats what got me wondering.

I have done quite a bit of research with no luck.

Thats why I was asking about the actual plug size in the hope they were the same.

 

well they don't make it easy. I was able to locate the parts catalog for the 5HP24 and the part number is listed as
01.220 0636 308 025 Screw Plug M18x1.5
See page 8

Now I wasn't able to match part numbers but this guide I pulled down from a bimmer forum appears to be the same part.
See page 5 for part size.

So fill plug appears to be the same but how long the tube is in relation to the distance from the x350 fill plug to a mounting point in the engine bay is another question.

 

Thank you Sean for the research!

Now I have to examine clearances etc to see if I can fit this kit.

It would be very useful in the last phase of the fill process and for checking fluid level once in a while.

 

Agreed and I think the whole process of lying under a running car while filling your treaty will be eliminated. I'll be watching with interest as my XK has the same tranny. I'm subscribed to this thread.

It might not be too difficult to fabricate based on the pic. It would essentially run along the case until you run get to the converter. In theory, the bottom of the tube would have fluid in it.

I just did an oil/filter change as well as a fuel filter change where I had the undershield off.
So it may be a while before I get under the car again.

I just need to figure out the routing of the filler tube. I am sure it can be bent slightly with heat and the right bending tool and it does not have to be vertical, just reachable.

The outlet at the tranny must be horizontal. At the appropriate temperature when the fluid is supposed to drip out of the fill hole the end of the dip stick should just show contact with fluid.

I just ordered the kit anyway.

 

Quote Sean W :"It might not be too difficult to fabricate based on the pic. It would essentially run along the case until you run get to the converter. In theory, the bottom of the tube would have fluid in it".

This could be an issue.

We know when the tranny is at the correct fill level within a certain temperature range with LG6. That is it drips out of the fill hole when car is level.

With the dipstick tube horizontal at the hole you may not be able to see on the actual dipstick whether you have the correct fill level.

For that reason I think it needs to slope upwards exiting the fill hole. You would be looking for the tip of the dipstick to have "some" oil on it but not dripping with it.

Now if you can establish that level initially then at normal running temp you could establish that level later on the dipstick?

Ok just read the other thread in detail. The dipstick rests in the 90 degree bend not all the way at the end and is supposed to be calibrated for normal operating temperature.

 

That was my assumption, that you could only check the fluid level when normal operating temp.

I'm hoping you get it fitted. I would assume you would have to check the level using the current method, then immediately install and check the dipstick so you know what "filled" actually looks like in your model.

Of course if you don't have the make and significant bends to fit, you'll be set, because you'll see and snap a pic of the dipstick end as shipped and then after you modify it to fit so hopefully it's in the same position.

 

My thoughts exactly.

I have to make sure the transmission is at the correct level. Than once installed at with the transmission at the fill temp take a reading then again at normal operating temp.

If we get a warmish day in the next couple of weeks I will look at installing this "kit" and take pics along the way.

It will be interesting to see the color of the fluid as I changed it only about 6,000 miles ago.

 

All I received was the actual dipstick itself nothing else!!!

I managed to order from the wrong site somehow.

I am going to wait until I have checked out a route for the tube before I order from the correct site.

 

Bummer

 

I have not given up.

 

I've always wondered if the deep pan/dipstick setup for the Mustang would work. Not really sure how much modification it would take, or how much of a liability the pan would be- especially on a lowered car. Might be worth looking into though
