    I have a friend who has a Proton SAVY. He took the car to Proton Shah Alam for service twice, but they could not identify the problem. They changed the accelerator pedal and that was all they did. Here are the problems:

    1) When the car is stationary, when the gear is in neutral, once a week, the SAVY's engine starts doing the REV of 3,500 RPM when the gear is engaged in "D". After 30 seconds, the gear indicator on the driver's panel starts shifting from "D" to "1", then "1" to "D", with the RPM dropping from 3,500RPM to around 1,200 RPM.

    2) When the car is on the move, when the driver is not stepping on the accelerator, the SAVY starts doing around 4,000 RPM, providing a suddent surge of power to the car. The gear changes automatically, possibly shifting down when this happens.

    3) When the car is on the move, the engine suddenly dies down, and shuts down completely. The brake does not work when this happens (well, it works but it takes the all your force and strength to slow down the car !!!!! DANGEROUS !!!!!). This happens when the car is doing 50km/ h or at any speed. The gear changes suddenly and the REV chages & the engine shuts down completely.

    Proton in Shah Alam has not been too technical about this matter. To date, they have only changed the accelerator pedal, which has not solved any of the problems mentioned above. They have cleaned the Air Flow and checked out the sensors, but they have not managed to sort out the problem.


    Is this due to ECU? Or is this due to the faulty gear box? Or electronics that controls the gear shift? Does anyone have any ideas?? It would be good if you could share some of your experience & knowledge.....Thanks !!!!

    tell them to try swapping the ECU 1st, then TCU.

    Thanks for your advice. However, the Mechanics in that big service centre in Shah Alam checked the ECU and said there is nothing wrong with the ECU.

    They said they can't detect any faults in TCU either. They said that TCU costs RM 2,000.

    Any other suggestions???

    You can check savoc.net. Many proton Savvy owners there.

    This is why i sold my Savvy. I was not confident of the expertise that proton has.

    looks like its the infamous AMT problem. I actually have a spare TCU, if there is a problem with the TCU, can sell it to you at much cheaper price compared to Proton.
