Thanks for the replies everyone! Sorry in advance if the multi-quoting is incorrect, for some reason the Multi-Quote Button was not working so I had to copy and paste each one individually.

I figure that if (when) I open my transmission up to replace the mechatronic sleeve, I'll replace the fluid and the filter too. And as the ZF fluid is so darned expensive (here in NZ it's scary $$$) I will replace all the seals while I'm in there, to save $$ and time later. As the seals age and harden, they don't seal properly anymore. This can cause fluid pressure reduction and can lead to slow shifting, hard shifting and other problems. I have no idea what your (or any) mechanic would consider a "transmission service" - you would have to ask them to clarify their statement. I only know what I would (will...) do once I open it up.

Link below from Bavauto website talking about ZF transmission fluid. It convinced me of a drain and fill, so good sales tactic!

Hey OP, my knocking was constant every drive and especially when pulling away from traffic lights on an uphill incline and turning right. This is a strange phenomenon that others have reported too. Must be the way the torque forces acts on the shaft.
Like is said, I held out for another 50k kms before the rebuild which cost $5.5k. I called a few places as well as ZF Aust Head office and in the end I chose CATS in Broadmeadow and they were brilliant. It's a family run place and didn't give me any BS. They offered to diagnose everything for free to try and avoid the rebuild but even they said it was too far gone. Only took them 4 days to complete and they offer 1 year warranty. Don't be too eager to buy the newer X5's as the build quality of the e53 is far better. Good luck. Sent from my iPhone using Tapatalk |

This transmission goes through solenoids rather prematurely. My 4.4 went 196k or so on 2 sets of replacement solenoids and a set of rubber seals. Had the massive 2-1 slam and new solenoids fixed her right up. I ALWAYS swap fluid to get the old junk out in all of my cars. My 4.8is is no different, no real issues but new solenoids helped out the cold jerks which occured once in a while. My X5m is up next.
Just placed Raybestos Stage 1 linings in my E55 trans, wish they made something for the M trans.

I did this on my E70 with 6hp26 ZF tranny and after research I used Ford Mercon SP.
Bought 7 Qts for around $60 and it's been shifting smoother ever since. The mechatronics sleeves, the bridge seal and the solenoid seal is really easy to replace. |
