Hello ZTH forumers,

I bought a 2nd hand Perdana V6 2007 two years ago. Now the gearbox is giving some problems.
For the 1st 3 seconds of driving, there is a rough vibration feeling & sound and then slowly it will become smoother.
The other problem is that when I maintain a speed of 110-120 km/h, the gear will drop into 3rd with a loud sound and massive jerk. Sometimes it will go to back to 4th gear or either it will maintain 3rd gear until i stop and switch off my engine.
Please advice on the most economical method to avoid this problem and aslo which workshop do i go to. (my location is in USJ)

Thank You

Yup, the GB need to be maintained properly, not until problem come then maintain.

Have you change the ATF, ATF filter? Some valves may be acting up. You can try some ATF additives and if still does not help looks likely need an overhaul already....

With those symptoms and that car of that age, just got rebuild it and install an atf coooler. You can flush and change filter for a possible temporary solution, but then it wouldn't last long and you will have to rebuild it fairly soon, hence wasting your labour charge and fresh ATF. Rebuilding is not exactly cheap and would cost around 2.8-3.2k. But once you've done it, it should be good for 10 years or more if maintained well.

Cheap and possibly temporary solution : Flush the gearbox and change the ATF filter and use Lubeguard additives.

Probably permanent solution : Rebuild the GB

that is why the price of manual GB has soared pretty high in the recent years....

2007 is the SEi model, right? That model the GB really bad. My VR when NA time is the E33A, it was auto and had similar GB. Mine was change with chop shop GB before I bought over and it lasted 6 months only, thereafter I did my transplant of the VR4 engine and manual GB in....

the eterna gearbox will give similar problems, no point changing or overhauling it, the problem will be back after a while.
permanent solution is convert to manual as my previous post.
