Has anyone (mild hybrid AT owners) thought about how you would go about changing ATF for the torque converter unit? I understand it can't be drained completely so its more like drain and replenish the same amount of oil, but I am unable to get a satisfactory answer from A.S.S and they don't seem to be interested in doing it. I don't need to change it anytime soon but plan to do it around 50k kilometres mark and then repeat the process every 20-30k kilometres thereafter.

Hi all - has anyone taken their strong hybrid GV to high altitudes? I am taking mine to Ladakh next month, and would appreciate inputs from fellow bhpians on what to expect in terms of :

1. Performance while climbing high altitude passes like Khardung La, Chang La etc

2. Any precautions to take while driving in cold, dry and regions with less oxygen.

Thanks!!

My experience with oil change in AT gearboxes of Santro, old Grand Vitara & Jimny is as follows:-
Drain the AT oil and measure the quantity drained. Top up with the same quantity. Ensure that they change the drain plug and its washer. Drive the car for 15 days or so and repeat the procedure. This will ensure that majority of the oil is fresh.
Ensure that the service folks pre-order sufficient quantities of the AT oil grade.
For reference Santro and old GV drain 3.5 litres while the Jimny drains 1.7 litres each time.

You can then repeat the process every 4 years or 40k kms.
