Pre facelift E63 AMG 7g+ autobox issue.

[Bobby Dazzler]

I've only done about 500 miles in total from buying the car to now.
Probably 300 from gearbox service to today.

It’s a shame, that’s too close to eliminate the service, but not close enough to be confident of a link.

If the transmission specialist has a good reputation then I’m sure he’ll want to investigate further.

my issue was a very harsh lurch into 4th/5th same with the downshifts, now it is a hell of a lot better after a software update from automatic transmissions at preston, i'd give them a ring and go over he will look at it and tell you the best option.

Very similar problem in this video below to what I am experiencing with my E63 (flairing revs etc).
The guy takes out the whole gearbox and wet clutch/torque converter, only for the problem to turn out to be the tuning remap.
I've had mine stage 1 remapped, so maybe that's the problem?
However its been fine up until a week or so ago, can remaps even go corrupt?

I'll have a word with the tuning company when they open in January, see what they can do, but now I've seen this video, I think this is the first port of call.

When did you you have it remapped, and how does it fall between other events in terms of time and mileage?

I bought the car 17th Oct, has the gearbox service on the 24th, then the diff oil change a week after, all was ok apart form the slight judder setting off in 'C' 2nd for a mile or so, I hadn't noticed this before the gearbox oil was done, but I was still getting used to the car.
Then I had the car stage 1 remapped about a week after this, again all was fine.
I then had a full stainless cat back exhaust system fitted, again no problems.
The only thing that has happened really in the last couple of weeks, is the car has sat unused for days at a time.
I'm going to disconnect the main battery overnight and see if this does anything.

I haven't read of this problem with a M157 remap, is it common? (I'm getting a stage one map on my E63 In Jan).

Sorry, OP, for the thread hijack.

I honestly can't tell you mate, because I really have no idea.
I will keep the thread updated with the eventual problem outcome.

If I'm honest, I have a feeling its still a gearbox problem, rather than the map, but until I have a word with the tuners, I have no idea.
My first port of call is to get the gearbox oil level checked, also to make double sure the gearbox specialist used the thinner correct spec Mercedes oil for the 7G+start/stop box.
Then move onto having the latest software uploaded and the adaptions reset.
If this doesn't sort it then its gearbox stripping time I suppose

Mine has been fine since a remap although it can be a bit hesitant setting off in anything other than C mode until the ATF has warmed up.

Cheers. Very best of luck with it.

Hi

Can i ask if you have only just got the car why did you have a gearbox service carried out ? Was there an issue or had it been missed on service?
When the garage carried out the service did they reset anything ? Reason i ask is if they have reset the adaption data of the tcu then it will not remeber the shift points and the filling pressure of the valves etc and so will go back to a base setting. I have seen this reset by accident from a garage and we ended up having to carry out the full gearbox service and a full gearbox adaption to re teach all shift points again. First things first if you are confident the correct oil was used. Get the oil level rechecked think its done at 45 degress. Should be a green oil filler pipe in the oil pan but you can double check all this with you local dealer. Maybe there is air in the valve chest the later gearboxs 9g have a flushing routine to bleed all the valves etc. If all this is good and you still have the issue id recommemd getting it to an indy or main dealer with xentry syste,m and see whats going on they should be able to pick up the internal data

I looked through the sevice history and the gearbox had not had a service, just for peace of mind I had it done along with the rear diff.
I've no idea if the gearbox was reset after the service.
There is a local Merc indy in my local town, I'll give them a call on Monday and get the ball rolling.

The revised tube is always supplied, and shouldn't cause any of these symptoms.

Additionally, adaption resets should not be carried out during a gearbox oil service.

I would get it back to the garage, and get them to check the levels one more time. I'm sure they will be happy to double check their work.

I would check who has done the remap, if somebody reputable then very unlikely to be causing the problem, but you can always update the ecu to wipe the map and rule it out.

Just a quick update on this,
I disconnected the negative lead on the main battery under the bonnet.
This was disconnected for almost two days due to snow.
Reconnected today and done 50 miles (45 miles on the motorway).
Instantly I could tell the gearbox was smoother, no judder setting off from cold in 'C' 2nd.
Initially the rev flair was still there whilst on the motorway at a steady 60 - 70 mph, this got far better towards the end of the journey, almost to the point of struggling to make it do it near the end.
I had a short drive back home after coming off the motorway, the gearchange is much smoother, but still slight flair just as it changes gear 2nd to 3rd.
I hope the gearbox gets better over the coming days, but I am going to get the gearbox level checked and have the latest software uploaded.
This video below was the car on cruise control towards the end of the journey, last week the car would have been flairing about 200rpms at the same location.
This was coming up the long hill from Lancs to Yorkshire M62.
I accelerated very slightly, as you can see still some very slight rpm movement.

Going to get it booked in today.
Fingers crossed it's software rather than a mechanical problem.

 

[Boristheblade]

Car booked in with Auto transmissions in Preston on Friday.
I will update the outcome.

Whatever they say, get it checked elsewhere/second opinion before going ahead with any expensive repairs that they say needs to be done, not saying they wont diagnose properly but once they start work it could be like using a builder a money pit with no end or fix in sight.
