Been driving the 2008 E60 for the past 3-4 years. Had some persistent gear related issues intermittently and thus decided to go for the plunge despite having only 2 years left in the COE.
Read up quite a fair bit on the mechatronics/gear related stuff and realised that quite a fair bit of the 'issues' that I had been experiencing are all somehow linked to the mechatronics.
1. Shifting of gear from P -> D or D ->R or to P will sometimes have loud metal clanking sound coupled with car jerk.
2. Coming to a stop at traffic junctions will have a slight jerk just prior to stopping, as the transmission changes down to first gear. Sometimes the car will even vibrate and then shift to N by itself and engine cuts off.
3. Overtaking was also slightly slower as the gears took an extra fraction of a second to engage after stepping on the throttle.
4. Occasionally, upon starting of engine and moving off, the engine will tend to rev up with the throttle, but the gear does not seem to to change, and when it does, the car will jerk or vibrate suddenly as it shifts gear, due to the revolution already quite high.
5. You have the message "Transmission Faulty" when you start off and totally no power. Message disappear and car appear normal when you off and restart the engine.
As the COE only left 2 years, and unwilling to get a totally new mechatronics set, upon discussion with my fav workshop managers Gavin and Randy, I decided to change the solenoids, sealing sleeves, mechatronics plate and pistons. (with tons of AT fluid!)
The workshop was able to complete the overhaul within a day and upon collection, the first feel of the drive was like, "Woah! Why did'nt I get these changed a year or 2 earlier!??!"
When I had the car, the mileage was like 90K, and some of the above issues were already there. Being a first time BMW owner/driver, I thought it was normal (lol). Furthermore, I drive on highway quite often so did'nt really have lots of stop starts(gear shifts) and thus the above issues were not very common. Now at 190K mileage, the effect of the change is phenomenal (for me, at least) and my only regret was not getting it serviced earlier so as to enjoy the ride for a longer period while the COE lasts.
Now the shifting of gear from P to D to R or back to P, it is quiet, seamless and a total contrast to my past 3-4 years of ownership.
I would like to state that this solution may not work for all cars as it could be the mechatronics template (the main metallic rectangle shape thingy) or the mechanical parts of the gearbox that is failing, and I am taking a risk here just to change the most obvious parts.
I would like to thank Gavin, Randy and the team at Revol of their professionalism and expertise in helping resolve the issues plaguing me.
I guess I can now enjoy the 'real' feel of a Beemer performance, at least for the final 2 years....
