![]() ![]() Many manufacturers use synthetic fluids in their transmissions and have change intervals around 100,000 to 160,000km. And of course, only manufacturer approved fluid and filters should be used.Īs complicated as it can be, it should still be done to help prolong the life of the transmission, which can cost upwards of $8000 to replace. The risks and potential costs of servicing automatic transmissions has gotten to the point where, in our opinion, it should only be done by dealers or independents who specialize in the particular vehicle. It is not uncommon to hear of a car with a properly shifting transmission that went in for a transmission fluid flush and came out with a slipping, essentially broken, transmission. Even a lowly Hyundai Accent has a 6-speed auto, and automatics with as many as 10 speeds are not far off. Some are so complicated (ahem, technologically advanced) and so ridiculously expensive that servicing them has become tricky business. Modern automatic transmissions can be a real tough cookie. While many synthetic oils do indeed have many advances and benefits which can allow an extended change interval, we would never leave any oil in any car for 30,000km.įor cars which use synthetic oil, a change interval of 8,000-10,000km is usually fine for most cars in normal driving conditions, and 7,000-8,000km for severe driving conditions.įor cars which are driven less than 5,000km per year, then it is recommended that an oil and filter change be performed at least once a year. This could be an acceptable interval under normal driving conditions, however, as mentioned before, we Canadians must follow the severe maintenance schedule, which means that the interval should be 5,000-6,000km.įor cars which use synthetic oil, manufacturers typically recommend a change interval which is generally longer than that of conventional oil, sometimes upwards of 30,000km. All vehicles in Canada should follow a severe maintenance schedule.įor cars which use conventional petroleum-based oil, many manufacturers recommend a change interval of 7,000-8,000km using their recommended oil and oil filters. Severe driving conditions, on the other hand, are considered those in which a vehicle is driven short distances, infrequently, or in extreme weather. Normal driving conditions are considered those in which a vehicle is driven regularly for extended periods of time, such as highway driving, mild weather. The appropriate oil change interval for any car is dependent on a number of factors which include: 1) What type of car you drive 2) What type of oil your car’s engine uses 3) How far, how often, and what type of driving you do. There is a limit however, and, in our opinion, no car should go anywhere near 30,000km without a service. Modern car engines, as well as modern lubricants, have evolved to the point where extended (beyond 5,000km) oil change intervals are possible. There is truth and logic to both sides of the oil change debate, however, neither one is perfectly correct. So who is right? We will take you through each type of fluid to determine the proper intervals for each. On the other side, you have the old-school mechanics or car owners who swear by the 3 month/ 5,000km oil and filter change interval, no matter what anyone says. On the one side, you have car manufacturers which will try to convince you that their modern cars can easily go 10,000, 20,000, even 30,000km in some instances between oil and filter changes. But I will in the next 5-6 months.As far as maintenance is concerned, fluid changes are probably one of the most debated areas. So, to cut it short, no haven’t done it so far. the 4 Speed Torque converter’s ATF was available though. They said you’ll need to order it in advance. However, there was no stock of CVT Green 2. With Maruti, the SA relented when I insisted – I anyway knew far more about Automatics than he did. Slight roughness disappeared completely in my Honda and Hyundai. ![]() My VW, with it’s notorious DSG 7 speed is smooth as silk after 5.5 years. I managed to get fluid changes done at Honda, Hyundai and VW – much before scheduled intervals. Can anyone suggest how to find out if the CVT fluid is going bad?įrom my experience of owning Automatics a little more than a decade, the Service Centre chaps hate doing work on ATs – only select mechanics receive training to work on an AT fluid changes require a proper flush or ‘cycling’ to get rid of residual oil in the gearbox – much more time consuming than a normal gearbox change In DSGs, there’s a mechatronics learning manoeuvre which needs to be performed in an open space – a time consuming job without much monetary returns per hour. ![]() I am still searching for a way to understand the check the fluid and plan for replacement based upon its condition. Have any of you changed the CVT fluid yet? Neither me nor BHPian Oxy below found anything concrete from the service center. ![]()
