I do not remember any replacement or top up of transmission fluid. This may be the problem. Quote:

Drain and replace the AT fluid (No top ups). If that doesn't solve the problem I guess a gearbox overhaul is in order. |
I guess this might be a potential solution. Quote:

I have never checked the ATF. Can you pl guide me in how to check it - I have seen the engine oil dipstick, but no idea where the ATF checker is located. Quote:

Sound like your problem is more complex, though. |
Let me check this - the ATF replacement. If that does not work, we'll have to look for a capable service advisor trained in AT systems. Quote:

Same is my case - no service advisor ever told me anything about checking/ replacing/ topping up of transmission fluid. Quote:

For i10 the AT fluid should be replaced every 40000 kms (as per user manual) for 'severe usage conditions'. Other wise its just inspect after every 10000 kms and replace if necessary.
Severe usage for AT equipped car amounts to:
repeated short distance driving
driving in dusty/rough road
driving in sandy area
more than 50% driving in hot city traffic above 32 degrees C
driving in mountain
towing a trailer
driving as patrol car/taxi/CV
driving in very cold weather
as sen2009 mentions that his car runs between mulund and powai amidst heavy traffic and not so good roads, I guess it can safely be termed as 'severe usage' and the AT fluid be replaced immediately.
PS: For me points 2 & 4 holds true and I shall make sure to change AT fluid at 40K kms. |
Given the conditions, my santro is definitely in severe usage category. The road is very bad and traffic is bumper to bumper for the whole 9 Kilometers.
Thank you all for the help. So far my action points are as following -
1. Find the dipstick and check level/ color/ condition of the transmission fluid.
2. If inadequate (even if it seems ok) - change the tranny oil.
3. If this does not solve the issue, look for an experience AT mechanic in Mumbai.
I shall try this in the following week and report back. Meanwhile, please help me with any other advice you may think of.
PS:- In case of manual transmission cars, one would normally check the clutch plates for such a problem (engine revving and a delay in pull). Is there any similar clutch like mechanism in AT gearbox which I should check?
