ML Gearbox question

[santefe999]

Hi.
I wonder if any of you can help me with this conundrum. Having owned an ageing W202 for nearly four years and been so pleased with it I decided to make my other car a Merc as well. I sold the Nissan Xtrail and purchased a very nice W163 M270. The two cars are worlds apart and I am very pleased with the M Class. Both Mercs are automatic and have Tiptronic gearboxes. However, they seem to behave differently. With the C class if I am driving along in D and use Tiptronic, the gearbox will always change down and show 4 on the dashboard unless I flick it down again when it will show 3 etc. The M class, however, behaves differently. If I am driving along in D and flick the tiptronic the box will change down to the next lowest gear from the gear I am in at the time. ie. If I am in fourth gear the action will drop the gearbox to 3 and show 3 on the dashboard. Now my question is this: Are both cars behaving as they should or is one of the gearboxes faulty? I have it on very good authority that the C class gearbox is working correctly but I wonder if any ML owners out there can tell me if my M class is behaving itself. Heres the stats. W163 ML 270 CDI. Special Edition 2005 on a 54 plate.

Hello

In my ML, if I want to slow down for a roundabout if bobing on say I can do one of two things.

1) Push the gear lever to the left and hold it there and the gearbox choose the best gear to be in given speed.

2) Flick the gear lever to the left and it changes down each time I flick it, so if in D then 4, 3, 2 1 etc. However if you are doing 50 say and try to put it in 1st it will not let you.

thats how mine works and guess yours is the same? (ooh its either flick to left or right without being in the car you do it automatically... one ways is up one way is down)

I have a C-Class and ML too. The C-Class functions as you describe - I'll need to check the ML.
