Hello Scotty,
I have a Chinese car, Changan Eado 2020 which has an Aisin Warner 6 speed automatic transmission (i think it's a toyota transmission?). The car clocked 160k kilometres and I noticed the transmission is starting to jerk and shift roughly at low speeds especially when the car is slowing down and downshifting. Does this mean the tramsmission is on it's way out or could just changing the fluid fix it? I have changed the fluid twice so far every 60k kilometres.
Aisin is part of Toyota but they do make transmissions for other manufactureres that are not used in any Toyota model.
See what your fluid looks like but if you're changing it every 60K kilometers (something like 36,000 real miles, I think) it should be OK. Is there a filter to be changed as well? If that has not ever been changed it could be clogging up and impeding the flow of fluid. It would be helpful if it could be scanned for transmission codes but that will probably require a professional-grade scan tool.
All Toyota models or most of them have Aisin transmissions and Toyota owns like some percentage of Aisin. Your transmission shouldn't go bad especially at 160k kilometers ( 100,000 miles ) that's pretty low for transmission to go out at that mileage. We have 06 Camry with 375k miles ( 600k kilometers ) with the original automatic transmission and still runs fine. Since you keep up with the fluid change I would advise you change the transmission filter and see if it fixes it if not then I would check with a mechanic to make sure if it really is the transmission gone bad. And see from there what you wanna do with it. Good luck.
