![]() This reasonable given on 8 speed automatic transmission there is no dip stick, the trans oil has to be heated to specific temperature where it starts to drip out of the fill port. Not sure what year and model OP Toyota is but I had the transmission oil change for 2019 Highlander at 50K by the dealer and the cost was $120 for everything. The problem arises when a fresh trans fluid is added to the worn out transmission- The clutch might start slipping or the car might refuse to shift out of gear" Sometimes this extra friction from the old oil is what keeps the clutch working properly. As the oil gets old, it becomes thicker and becomes less slippery. "Transmission oil is really thin so that it can move around the crevices of the automatic transmission. Regarding the why its a bad idea to change fluid on a high mileage car still on the original. That being said, if you have a beater and you're planning to drive it into the ground, the right thing might be to leave things be. I'm a car guy and wouldn't dream of not doing the right thing. Plus doing it myself gives me the opportunity to check for the condition of the fluids that can give me clues about how healthy things like differentials and transfer cases are. I follow the manufacturer's recommendations and change fluids because those components can operate better with fresh fluids - it's about longevity and performance. Less if you tow/live in a mountainous area. However, you won't be reaching 300km on that tranny. You either do it at the recommended intervals or you leave it. You do a tranny fluid change when high mileage and you never did one before, doing the tranny fluid change will wreck the tranny. ![]() These places are in business to make money, so don't just blindly go with it unless you have money to burn or you are really high milage. My wifes current car, a 2009 Pontiac Vibe needed a tranny fluid change like 7 years ago according to the oil change was never done, still drives just perfectly fine now. Most tranny fluids are good for life of a vehicle unless you are doing towing, and power steering, well I never even removed the cap on one of those ever.and somehow all my cars are perfectly fine and I never had any failures with any of those things. I am on the camp that basically never in my entire life changed tranny or power steering fluid on a car.like EVER. Without going into my usual tirade on why "lifetime ATF" is a complete joke (and not just by Toyota), I would refer to your Owner's Manual under "Severe Driving" if you're towing/using the vehicle more heavily than normal driving otherwise 100k is a good average to go by.So humor me for a second. 100k under normal driving is not a bad idea. Some people consider "Drain and Fill" just doing it once, to me that always seemed wrong so I tend to use "Drain and Fill" and "Flush" to indicate the same thing in my way of thinking since either way I am going to make sure the fluid looks as close to new as possible.Īs for the service interval. I ran about 12 quarts of fluid through the system by draining and filling the transmission oil pan until the fluid looked new (you get about 3-4qts from the pan), then I performed the fluid level check/adjustment procedure and was on my way. This is what I do on customer's vehicles and what I did on my '04 when I serviced my transmission last year. Now then, when I use the term "Drain and Fill" or "Flush" I tend to be a bit all over the place, as I am used to draining and filling transmissions multiple times to "flush" them with fresh fluid. Mentioned, minus a machine to do most of the work for you, but the principle is the same. But, using a "Fluid Exchanger" that hooks inline to the transmission cooler lines and uses the transmission's own fluid pressure to swap out fluid works without hurting anything (this is based on how these machines work and what a lot of people have done and had no issues with.) You still need to double check the fluid level via the annoying method Toyota has because it has no dipstick. Toyota states NOT to use a machine to flush our "sealed" Transmissions that use WS ATF.
