I am kristof, work for punch powertrain (cvt supplier for proton saga flx flx se exora, and the new car sold soon).
You can adress all cvt questions to me, as i consider end customers to be highly important.
Questions i saw:
Sound when engage D, not normal, not cvt unless you feel a firm shock when engaging, when not probably mounting.
I am Kristof, Belgian, living in Malaysia and working for Punch Powertrain (CVT supplier) as manager customer care Proton.
You can ask me all CVT related questions.
First answer is on the Reverse sound. Don't worry there is absolutely nothing wrong with your gearbox.
We use a planetary gear set that reverses the engine movement to our gearbox. This planetary set contains small gears that run at higher rpm in reverse, that is the sound you hear. It should be in your owners manual as well.
As soon as you start reversing slowly the sound gets less.
You succesfully contacted me trough email. After meeting today in sri petaling and flashing the latest software i hope your problem will be solved. If not, you know how to find me.
To all users, i am very sorry to be late in replying. It's as tan can confirm always more effective to email me. I am currently busy to get our service center in Subang jaya up and running.
