Aspri Clutched July 27, 2004 Share July 27, 2004 My ATF is only changed every 40,000 km and I've never had any issues with my auto transmissions in the cars I've driven. StarsAuto is probably right in this case unless you have a different engine or have done some mods that will shorten the effectiveness span of the ATF.

Godfinger Neutral Newbie July 27, 2004 Share July 27, 2004 Hi Changing the ATF oil at very frequently will not damage the Auto Tranny unless you have loads of cash to spare. Mind you that every ATF oil change costs min S$80 ( Synthetic ) Therefore, the recommend oil change for auto transmission is tagged at 40k interval. But some people are just too mindful and even went way after 80k on the odo. Optra's Auto Tranny is a 4-speed Fuzzy logic tranny so therefore there are still planetary gear set inside the tranny unlike CVT whereby there are only flexible cam and expandable belts. If you delay the ATF oil change interval, you will notice : - Delays in accerleration - Delay in upshifts, downshifts - trembling,Vibration when in 'D' mode with brakes engaged. - High Fuel consumption. - Noisy gear changes. If the problem is not rectified, you will encounter : - Difficultly in shifting into reverse. - Engine's die off when 'D' is engaged with brakes on. - Unable to shift from 'P' to 'D' Link to post Share on other sites More sharing options...
