Transmission and transfer case fluid change help please
What’s up guys. Can someone please post up a definite proven way of changing out the transfer case fluid and transmission fluid please. I’m going to have my mechanic do the work. He’s very knowledgeable. Just want to text him a link on how to do theses 2 fluid changes so it helps him out if he needs additional information. Thx in advance.
Transmission (be sure to heed not removing the WRONG CHECK LEVEL PLUG) = reverse band is let loose and repair is costly. That's why if you read my entire thread I didn't use the approved Jaguar check level procedure.
There have been vast amounts written and posted on this topic, but always there is uncertainty in the minds of the newcomers about the exact position of the Drain, Fill and Level plugs that in the worst cases lead to the Reverse Band Securing arrangement being disturbed.
I offer the following photos of my 3.0 Auto, MY2006 to help the identification and a copy of an article I wrote for the JEC magazine recently on how to do it
First the Drain Plug - easily identified in the base of the 'box. The arrowed crossbrace is not fitted to all models
The Fill point. Battery removed to show position clearly.
The Level Plug. The one that mystifies the newcomers because it's in the base of the 'box, near the gear change cable. It plugs a fixed, internal tube inside the 'box that goes up vertically to the correct fluid level.
Finally, the Reverse Band Bolt that too many guess must be the level plug! It's on the rear side of the 'box, above the left hand drive shaft. Leave well alone!!
Hope that helps someone!

Here is the link to the DEFINITIVE ANSWER on where the plugs are on Transmission and which one (and reason for it's location) is the reverse band bolt that screws your transmission if released.
I posted this quite awhile ago but it explains how so many people make the mistake of removing the HIGHER bolt to check fluid which is actually the REVERSE BAND bolt. It's internal design is counterintuitive to how you think it would work and what is normal for most transmissions.
I used Amsoil ATF for the drain and fill procedure. I used Dell's method.
1) pulled out the battery and battery box so I had full access to the fill tube and it was easy to pull out the plug and refill, no spilling. I used a turkey baster and small funnel.
2) I used a flat round plastic 7 qt. pan as a drain pan. I drained the fluid and about 3/4 of a gallon came out each time I did this 3 times.
3) I had 5 clear gallon water jugs. I would pour the oil in from the drain pan into a clean empty jug so I knew how much to pour back in.
4) I would drain the fluid, put an empty jug right next to the old fluid filled jug I just drained and fill an empty jug sitting next to it with new Amsoil matching the same amount that I had drained. After each drain I reinserted the drain plug..
5) I would then put the battery back in the car, start the car for 14 seconds off shut of the car, remove the battery and drain again.
I drained and filled three times although some do four. The first drain the fluid was dark but still had viscosity. The second drain was still dark but not as bad. The third drain was red and clear.
I used roughly 91/2 qts to do the job.
The Jaguar would sometimes shift hard when down shifting at higher speeds.That no longer happens and the car shifts so smooth you can hardly tell.
The entire job took about 1 1/2 to 2 hours. Very simple and easy.
Thanks Dell you are big help and your responses are always accurate. I don't have a manual so I just read your posts or Chris's (Thermo) and tackle the project.
