| Re: TUV300 AMT problems & Mahindra's inability to solve them One More - New Day New Problems: As posted by one of fellow TUV AMT owner from Faridabad, as he met with an accident and cheated a possible near death situation just because of a very unique feature of TUV AMT. (All TUV AMT owners please take this unique feature very seriously, as it can be a life threatening situation while overtaking or trying to run out quickly) Quote:

| Re: TUV300 AMT problems & Mahindra's inability to solve them My my! What a can of worms! Mahindra is doing everything wrong in handling these issues going by Mr Santhanam's reply to you. I do not know what kind of people Mahindra has at senior levels who give such replies to their paying customers. I am sure if Mahindra deducts even Rs10 from Mr Santhanam's pay cheque he will make a big noise and would not like to hear someone telling him that he is just making unnecessary noises. He expects his customer to shut up after spending 11 big ones?! ![]() Shame on you Mahindra. All the goodwill that you may have been generating all this while is just flying out of the window with people like Mr Santhanam at the helm to deal with such problem cases. Not only are you putting your customers through hardships but you have put people in charge who do not understand jack about dealing with real problems. |

| Re: TUV300 AMT problems & Mahindra's inability to solve them Utterly appalling. I have never been comfortable with these semi automatic transmissions and have always said that there are far too many variables to consider. What makes it particularly bad in case of TUV300 is the power or rather lack of it. I dont know how much Mahindra can do in this case but these are serious life threatening issues and Mahindra should be ashamed of selling a product like this in the market. Chuck the AMT guys, sell manual transmission only after you know of the problems. |

AMTs simply cannot be driven like MT. The vehicle uses lot of sensors and and the owner should first get used to it before venturing into sharp overtakes. When pressing the break, at 30-40 kms, obviously it should down shift, this should be done even on MT. However, if the vehicle comes to lower speed, to extract the extra torque you either shift down to quick surge or press accelerator and over a period of time the vehicle gathers momentum in MT. In AMT as the torque is decided by the sensors, for quick surge of power, at lower speed the vehicle will down shift. The above issue is purely how any AMT should function. I am afraid to say, some of the AMT users should seriously know the vehicle before making serious ventures. After all TUV is a heavy vehicle. I know good number of AMT guys who are doing really good!

People don't blame themselves for the situation they are in. What was the need to overtake when the gentleman saw a truck looming ahead and there was no space for all 3 cars? Who overtakes when a truck is coming at you? Rest other issue/s appear genuine, but I fear, this was/is a driver error. | |

BHPian ![]() | Re: TUV300 AMT problems & Mahindra's inability to solve them Sorry to hear about the troubles owner is facing. I personally own a Celerio AMT and has driven it close to 20000kms. So far the only problem i faced with AMT is, when going uphill or climbing a ramp. There i just switch over to manual and also use parking brake if i need to stop on an incline. Problem solved. Even in terms of overtaking, there will be a slight 1-2sec delay but downshifts upto 2 gears to compensate and complete the overtaking maneuver.so all in all AMT is good. I test drove TUV 300 84bhp AMT for almost 8-9kms, Only problem i managed to find in that short drive is that, it does not downshift as fast as AMT in Celerio. Still i would side with the owner and advise Mahindra to fix the issue for the owner. |

| This is the root cause of jerks or speed variations at slow speeds. As expressed by Abhinav from Faridabad in first gear TUV is programmed to move at speed of 9kmph and in reverse at 7kmph without throttle input. Now if a person wants to move at slower pace say @5kmph how it is supposed to be done. In order to achieve it what i do is keep on pressing brake to engage the clutch to slow down, but even with this it is not a constant speed it shoots up and then slows down. Any better way to do it, plz suggest In manual vehicles, we use various ratios of clutch to achieve this and thus have a constant speed. In TUV one more problem is 0--->9 kmph reaches very quickly, it is good in open highways but in close corners it is stressful due to variation in speed. |

It does take a bit of getting used to. But i totally agree with the posts above, that for all such features one must take time to understand the feature well and the utility of it. An AMT is never going to match the versatility of the MT in the hands of a good driver. As experienced by Rock18, each manufacturers AMT is bound to work differently. I think the manufacturers must start specifying a break-in period with speed limits like in the past. It gives the drivers a great feel of their vehicle through the complete range of rpms / gears before they break free and go nuts! ![]() Last edited by Nilesh5417 : 27th May 2016 at 11:29. | |

I asked him "suppose I take away the clutch pedal and force you to change the gears based on pre-programmed speeds, can you manage with only accelerator and brakes?" He had a blank look. Then I told him about Hydraulic box automatics and CVT automatics and how they offer infinitesimal control over speed which can mimic manual transmission with partial clutch but the same cannot be achieved by AMT and DCT and DSG. These will always be jerky and prone to "computer's interpretation of what the driver desires" eZee, a question for you and all the others who have plonked in their money with AMTs/DCTs/DSGs (TUV or any other makes): did you not do test drive before purchasing the vehicle - trying to simulate the usual conditions one encounters in his drive? Edit: 9 kmph creep forward and 7 kmph creep reverse is TOOOOOO high. It should be set at slower than walking speed (say 1 or 2 kmph). If someone wants more speed - he has all the means to press the accelerator pedal - doesn't he? Last edited by alpha1 : 27th May 2016 at 12:19. | |

Most of the TUV AMT buyers are firt time AMT buyers. many of them graduated directly from a manual hatchback or sedans. How is one expected to know about his vehicle or AMT? dealer's sales person or the person who gives demo of all the features only tells you how to start the car, shift to manual or automatic. At the most one will tell you that the car will skip few gears based on the pressure on A pedal to provide you with quick acceleration. So the most logical option left is user manual. There is no seperate user manual for AMT, its the same and all it mentions, how to park on incline or decline, and use mannual mode for mountains. Quote:

![]() There is something called 'getting used to' a vehicle. Its not a days affair. As I mentioned earlier every vehicle is different, forget models, within model itself. Some learn it quick some take time based on each individuals ability. Quote:
This is purely the driving style. Its necessary to understand the vehicle better before venturing into quick manoeuvres. Its not limited to AMT but for any vehicle. Last edited by LoneRidder : 27th May 2016 at 18:17. | ||

I am sorry to have sounded childish, but seriously I along with all my family members have heard of the term "getting used to" and we practice it too. I got the delivery of the vehicle on 29th November and I found the gear box painfully jerky and sluggish. Before I could practice getting used to this, I got my first engine knocking and truck like sound issue. In order to get used to it, twice I reached half day to office. Since I was not able to practice getting used to any more, dropped the vehicle at workshop and dashed a mail to Mahindra. It took them two weeks to return the vehicle back but this time with completely different symptoms. This time my family could not get used to of violent jerks AMT produced. So taking it seriously again, dropped vehicle with Mahindra. Two weeks later, got the vehicle with new AMT software, performance was good,*I was about to get used to it when engine knocking re-appeared again, after keeping it with them for a week, again I got new ECU flash. This made the box lethargic again. I again took my time to unlearn what ever was known about the car and here Mr. John from Mahindra R&D lands at my car's service without invitation. Mr. John finds, my car's clutch has developed a play say out of range by 30 points, immediately then and there he corrects the calibration and my car is behaving completely new, the creep is so aggressive, it gives exercise to my abdominal muscles. RPM manipulation gets introduced for the first time, but since I have a 8 MM thick matting which does not let the A pedal touch the floor, there is no way I could practice getting used to of AMT downshifting to give more power. Still I try my best to get used to of TUV so aggressively moving ahead without even A pedal input. And not breaking a sweat even with B pedal input. Since I can't get used to, I leave it again with Mahindra, who this time notices the matting, removes it and also discovers that this time my brake pedal sensor has few seconds delay, also works around creep function. The car is given back to me, and been a month I am trying to get used to of these features, in the process have had my bumper scratched and dislocated. During a joint test drive, I showed it to Mahindra that all the features kick in randomly, which means not in all gear shifts RPM and speed is managed, TUV does not downshifts each time the A pedal is pressed fully, it happens most of the time but not always, so how do I practice getting used to of this AMT box? Verbally I was explained that software decides based on the gear you are in, RPMs being clocked, engine temperature and exact position / pressure on A pedal. I felt it was too much for anyone to get used to without having a pilot's license or say without knowing exact mathematical algorithm or the logic written *in the transmission software upgrade. Currently though I have 3 family members who hold driving license, its only I who drive TUV300 due to these unique, random features which gets added or removed in each ECU flash Even if I go for 1500+ km road trip, it is only I who can / will drive as, if in 6 months of ownership, I still haven't got used to of this AMT box,*others however fast adaptors they may be will not be able to get a hang of it. That's why I have asked for list of these features, parameters like A pedal position, RPM, engine temp in which these features can kick in and I can start getting used to of these. With such a document, may be my wife or brother too will be able to practice the term getting used to and will be able to share my load. All this getting used to after paying 11 Lacs is painful though, seriously | |

| Re: TUV300 AMT problems & Mahindra's inability to solve them Okay, let me decipher some things for you folks from what I understand 1) Petrol cars can afford to have slower creep speeds since they rev higher, the gearing can be short and still the car can achieve respectable speeds in 1st gear when given the whack. 2) Diesels since they rev less and have high torques at lower rpms, the gearing is taller than petrols to compensate for the lower rpms to which they will rev, that is why the creep function in say a Celerio is much more manageable and even fun/good/amazing to have then compared to say a TUV in which the 1st gear takes you all the way till 9 kmph ( I don't know what speeds does Celerio reach in 1st gear when the creep function is on) 3) To counter this, Tata has done a Fantastic Job with the Zest Diesel AMT, no creep at all. Takes away the trouble of constantly fighting the brakes in traffic ( Although the car can roll back if on a slope). Secondly it behaves like like how an Activas throttle input would behave, if the Rev's rise above a certain rpm, the clutch engages and the car moves forward. Perfect for a Diesel AMT. 4) I feel Mahindra needs to remove the creep function in the AMT TUV's. That should sort this traffic problem for starters. Rest of the problems I have already mentioned my hypothesis on. |
