Yaris 2013 engine braking problem?
Hello everyone,
When i'm searhing about my problem, i found this great forum. My car is a Yaris with automatic CVT transmission. When im driving downhill at D mode and apply some braking to slow down, transmission always choses the lowest ratio and engine rpm gets high. Normally when i first buy the car, this was not occured( my be i dont realised). At D mode, i dont feel any engine brake at first, but lately this problem occurs. Is it a problem or a normal operatin? Thanks in advance. |

I'm not sure about the CVT, but with the normal automatic transmission that we get over here, if you are going down hill and do not touch the brake the car will free wheel. As soon as you touch the brake the car immediately switches into engine braking mode.

I would expect that the CVT is programmed to do the same; it would be easier to do and with less strain since there wouldn't be the sudden lurch downshifting. It's just how Toyota wants these things to run. I suppose eventually there will be an aftermarket module to change this mode. |

I think this also is different for different markets.
I noticed the JDM Platz and Succeed (which both have 1NZ-FE) they down shift automatically when going down hill and brake is pressed. However the AseanDM VIOS does not seem to do that. I tested this with my Vios and going down hill and pressing brake, the gear does not down shift. |

Many complaints about auto and manual toyota gear box? Toyota needs to address this. My previous car a Nissan Pulsar St 2001 model, it's gearbox is still strong at 298909 km's.
