Mahindra TUV300 : ECU Software update for the AMT

Sorry I lost the edit button to update my previous post, Mods please merge.

I got a second recall call just now. This one is for AMT ECU Software Flashing.

Anyone knows what this is and how important it is ? I have another highway trip of 300 kms planned for the weekend. So a bit concerned.

Moving your post out to a new thread so that other TUV300 owners don't miss it.

Thanks to Sharad Tater for sharing the following information:

Answer to the above post is - I had given my TUV300 AMT with Mahindra for half a month, for fine tuning of the AMT gearbox. The issues were:

1. Jerks during gear shifts
2. RPM needle sometimes going to 4000 rpm before the gear shifts
3. Gearshift was painfully slow
4. Creep function was very slow to pitch in, say it took 30 seconds before activating post braking
5. Sudden RPM dropping while shifting from 4th to 5th gear

All of the above issues were resolved with changes to the ECU software. The same software now is being updated in every AMT, hence the recall. I would advice all to take advantage of the improved performance that flashing the software will provide.

I had to escalate the matter up to big boss Mr. Mahindra himself. It was highly inconvenient to be content with a loaner vehicle, while your beloved newly acquired tank remained with Mahindra, but in the end, it all was worth it.

Regards,

Sharad

If the software patch actually addresses all the points mentioned by Sharad Tater in the post, it would be amazing. However, I would wait for existing AMT owners to test and confirm the results.

For instance, some jerks during the gear shifts is a characteristic of an AMT box. If M&M can reduce it significantly, if not eliminate it, it would be a commendable. Similar views for slow gear shift and creep function.

In that case, is this a 'Green' recall and required only to improve performance/experience (and not to prevent a failure or breakdown)?

Got it done today. It is a 10 minute job. But after that the car needs to be driven for about 10 kms for the ECU to get adjusted to your driving style.

Car feels quicker now. The gear shifts are smooth and quick. There was a lag earlier while shifting from 1st and 2nd gear and has greatly reduced now. Also, the creep mode is more pronounced now than earlier. Overall, happy with the update.

Taking the car on highway tomorrow. Will update after that.
