Perhaps I oughtnt to have used the word “clutch” and said AT system instead.

Yes, it is covered under extended warranty as per the Nexa dealers here. And that makes a lot of sense since the clutch is automated and driver doesn't have control over it. You should definitely push for a warranty replacement.

Sure, one can reduce the slippage by using manual mode for extreme inclines etc, but then that defeats the purpose of paying for an automated system.

Won't help.

In fact 2 weeks back, I would have asked the same question. But there are different types of ATs.

There are the AMTs which use software and hydraulics to shift.

Then there are CVTs.

The DSGs. The DCTs.

And the gods / experts know what else. Somebody should please do an article comparing the finances of all these. There are some write ups describing performance of each engine - GB combo. Does not satisfy the penny pinchers like me.

Somehow, it seems that Maruti's AMT as installed in Celerios are quite bad. Don't see the same complaints about the other Maruti cars (WagonR, Ignis, etc.). AMTs by definition is a cheaper form of an automatic, which unfortunately seems not to have been tested thoroughly (by Maruti).

Would like to see the AMT in the new Santro whether similar problems crop up. Time will tell.

Ok, I landed back from Germany after a few months and now my dad says that our Celerio is juddering again. Since he was the primary user all this while, he did get annoyed. Will get in touch with my dealer and get the clutch changed again. Quite pissed off at the moment just when I thought things were slightly better. I need to take a look at the car myself once since when I was away, due to battery going down the clock and probably ECM and TCM was reset. Guess sticking to the Polo with a seven year warranty on the DSG would have been a good idea if I had done this two years back.

Thanks do you have any written documentation,I got the clutch and flywheel changed at a cost of 6000rs. The extended warranty has stated that clutch is not covered. So this will mean I have to keep paying 7000 Rs every 15k Kms.

Unfortunately no! Nexa guys just told me this in person when I inquired about the extended warranty in detail. Why don't you write to MSIL? 15k is crazy indeed. Even if it's covered under warranty.

Typically classified as a wear and tear part, I am not sure if the clutch is actually covered under warranty. It has to be replaced under goodwill basis and especially if the problem has been recurring. In my case I can easily prove that not a single time the clutch has stayed good beyond 10k kms. That is not normal wear since my manual cars have good clutches even after 50k kms of similar driving in similar road conditions.

I brought the fifth year warranty looking at the AMT module in mind rather than the clutch issue.

Can you try using the Manual mode only when the new clutch is put in? However, on thinking a bit more about it, my guess is the slippage algorithm is at fault here. After considerable research on the subject, from my experience as well as my contacts in Maruti I think I might have a solution. I have heard about DSG remaps for VAG cars, could the same be implemented for the AMT gearbox's control units?

Could BHPians with knowledge about tuning cars help out here?

Come on, what's the point in using the manual mode if I got an automatic? I had posted about the slipping algorithm earlier. That will happen in manual mode also and is worse. Just leave the transmission in second gear and slow down to around 10kmph. Tap the brake and accelerate. The clutch will keep slipping until you cross 20kmph. This is what ruins the clutch since in dense traffic the car is mostly between these speeds repeated braking and acceleration will lead to constant slip.
Yes I would be glad if someone can remap the AMT module for me and remove this slipping mechanism. It's okay if the AMT dumps the clutch after shifting to second and there is a lag in acceleration for a brief moment while the engine speed picks up instead of slipping the clutch and giving a false sense of acceleration.

Exactly I tried to mail maruti but it gets rerouted to their service centre. someone who has contact with the administration may know something. As you say manual clutch fine but maruti can't claim it wore out due to bad driving.service centre manager is telling only if under 2yrs maruti is changing.

Probably OT for this thread, but ...

Saw in the Ignis official review that AMT is a bolt-on over the regular gear box. So, has anybody converting AMT to MT?

Other than fuel, what exactly gets saved?

Is the clutch the same?

Sir, no idea. Somebody close to purchased the Alto K10 AMT. And I was attributing poor shifts to inexperience. Now, I realise it is the AMT. Selling the car is a bit far fetched - it has done hardly 4k. Was wondering if mods are possible.
