LR3 Transmission service flush

Updated Breather Tube?

Did you get the updated front diff breather tube?

Did you get the updated front diff breather tube?

I did. My front diff was pressurized the first time I opened it up, so I picked up the updated breather right away. Pretty sad when they cant even get a simple breather right the first time.

My suggestion is to use Redline for the diff fluid. No problems with mine at 168k miles.

Strange on the diff oils as my mate and I changed ours in January, the oil on his looked like Coca Cola on colour when drained, he changed it again 3 months later and the new oil was also Cola coloured.

The oil out of mine was so clean I could have poured it back in the top.

Results were the same for front and back. His was dirty and mine was spotless. I have no records to show mine was ever changed as well.
Mine was at 120k and his was at 105k.

I would not recommend this on a locking rear diff. Normal diff sure. But locking has additives to make sure the clutches work like they should and don't wear out prematurely.

everything ive ever read has said never do a complete flush on a tranny... I know on my WK as well as all my other vehicles a simple drain and fill of both the tranny and converter with new filters installed upon refilling has suited me just fine. im not sure why this wouldn't be suffice for even a LR3

There's no way to drain the converter on the ZF trans in the LR3

I just changed my transmission pan, filter and fluid at 105K and what an improvement in shifting. Not that it was bad before, but its like buttery smooth now. There used to be a little clunk when going from coasting to a stop to back on power, but its 100% better than I ever remember now.

I am so up in the air on this. The old school guy says change it often or not at all. Rover says its lifetime leave it alone.

 

[proper4wd]

They eventually get changed anyways when the pass-through transmission electrical connection starts leaking. To fix that, you have to drop the pan. New pan/filter, new connector pass through with o-ring, new fluid.

For the guys who worry about flushing, think about this. When your engine is running its turning the trans pump which is constantly pumping fluid thru your trans cooler then back inside the trans. When you flush the trans you are doing the exact same thing except you return new fluid and capture the old. why does this concern people? just curious.

Sooooo.... This is a good discussion. From what I have read, it is definitely not a lifetime fluid. Ploughing arounnd threads for hours on through the Disco3 board has convinced me of this. Secondly, now that I want to do a flush, who knows of a centre that does one west of Philadelphia? I know, the most common answer is "find a transmission shop with a bunch of Bee Emms (btw, do you know BMW make cars?) and Mercs out front". Which is a good answer, but not too specific. I spoke to an Aamco shop who said they would not do it. The prejudice the chappy displayed was pretty entertaining. "they do it in England? pfft! That's crazy!":costumed-smiley-007

I spoke with a few shops about this and the ones that do the service say not to flush after 60k. What they do is
drop the cold oil in the pan and refill.
drive until hot and drop the fluid and change the pan.
Upgrade the sensor Oring
fill with fluid and send it on its way.

That sounds r e a l l y expensive! I know, cheaper than a transmission.
It is even more extreme than a regular pan and oil change.
Funny thing is, is this is how I did my Diffs and transfer case a few days ago.
Thanks for your input!

I am not sure if we are allowed to cross post to other forums, but I found this an excellent read and to be extremely edifying for those of us who don't always use the dealer!

A homegrown flush. Interesting to note that the pan, when changed was squeaky clean at 70k.
