LR4 Transmission Fluid Change: Pan Swap Option

[Azoo]

I currently have 174,000km which is about 110,000 miles. I bought when it was 168000km. So far i've done lower control arm bushings, tranny drain & fill which i just did yesterday, Oil and filter change, front rotors & pads , cleaned the trottle body and cleaned both mass flow sensors cause it was idling a little rough. My next task is power steering flush and spark plugs.

The tranny fluid was quite dark which i wasn't surprised for a car over 100k miles, I plan to do another drain and fill in the next 6 to 8 weeks to get more new fluid in there. But believe it or not the tranny still feels solid and now the gear changes are completely seamless after i changed the fluid.

I'm about 500 miles on the new pan and filter, and I'm still grinning. Smooth as silk. Did I mention that I changed ALL of my drivetrain fluids (diffs, TC, and tranny) for $257.48?

Pfunk951, what kind of fluids did you use for your diff’s and TC? Also, what kind of filling pump/system are you using?

Also, thank you for the very valuable info!

I originally changed mine at 65k oil didn't look too bad did old school pan and filter together PITA. Bought this conversion kit for my next change because I would never do it the other way again.

Ended up selling my LR4 but before I did I just flushed the fluid 88k and it was dirtier than I remembered, a lot of towing in that 20k, just something to consider.

I have an extra conversion kit pan/filter new in box. Britpart DA2142 I'll ship to you for $80 total. I think still about $125 online. Message me if interested.

I used febi fluids throughout

Has anyone performed this procedure on the 2014-on ZF8HP70 8-speed trans? I’m at 75K miles and am planning to give it a go once parts are back in stock. Every place I’ve tried is out of stock. Somebody must be busy at it.

I used Febi fluid, I've got about 9k on the truck since the fluid change and zero problems noted. I'm thinking at 90k I will drain/refill again, as I only did it once during the procedure (there is still old fluid in there as you don't get it all out).

For a pump, I used one from the local parts store, it looks like this:



Try not to buy one that is excessively cheap.. I have bought many in my days, and when the pump starts leaking/falling apart/spraying fluid all over you while your cheek is 3" away from a hot exhaust pipe, your patience will be... tested..

Thank you!

Just wanted to make sure I didn’t need the expensive one AB sells for some reason!

My LR4 has 66k miles, and it’s staring to feel a little clunky/rough on shifts, no slipping that I can tell though, so I’m going to do this soon.

I would also like to flush the tranny once or twice before I change the pan as well. Should I bite the bullet and do this with the Febi fluid, or is there something cheaper I can do the flush with? Any recommendations on how many miles I should put on it between flushes?

Can you provide a link (or product name/number) to the exact diff & TC fluid you used? I looked on the link you provided for the ATF, and it looks like there are multiple options.

Thank you!

Thank you for the Part Numbers...

Did you buy it from the same place you linked in a previous post for the ATF (rmeuropean)?

I searched those part numbers on that site, but could not locate any Febi brand, only Land Rover, Shell, & and Castrol...very strange.

I recently did this pan swap and service on my LR4 at 76K miles. I've done it on the LR3 earlier this year.

I too use 4 car ramps and leave the truck in access height.

Unfortunately the britpart pan I initially received had a stress fracture by the drain neck in it, that I did not notice until after doing the complete service and realizing that the pan was leaking a few drops every minute after completing the work. Apparently this a known issue with the pans themselves and AB sent me a new pan, filter and fluid. Which meant I had a chance to do the service twice.

At 76K, my fluid was quite dark but I also tow and use the truck offroad. The refill took almost 7 quarts.

stufrowin, if nobody else has taken it yet, I'd be interested in the conversion kit. I need to change the fluid / filter on our LR4 in the near future. I can't find any "private message" links on this forum, am I missing something? You can email me at qship1 at gmail if you'd like. Thanks!
