Many AMT owners have these problems, the rest of the AMT owners "are yet to have these problems". So i decided to write my experiences since i have already wasted enough time trying to tell Proton and to troubleshoot the problem myself. Problems here include "jerking & stuttling" "D to N" "D to manual and jammed" and warning light comming out intermittenly for no apparent reason.
Actually, the real problem here is wiring, not the clutch pump, because i have tried a new pump, and have changed oil seals also. The pump looks perfect anyways. But after all that the problem still persists. OBD software indicates these error codes: BATTERY VOL SHORT CIRCUIT, HYDRAULIC PUMP PRESSURE BELOW MIN THRESHOLD. Mind you, im using the right software.
Most likely the main problem is wiring, because wrong grounding and wiring can cause insufficient voltage and will overheat the pumps faster. The situation will be aggravated if you turn on all air-cond and lights at the same time. My car will last longer if i turn on nothing before the gear goes to "D to manual" and then to "JAMMED in the same gear" if you still insist on pushing the car. This is because the TCU will try to PROTECT the mechanical parts when they detect something is wrong. So all i do is i wait for the AMT to cool down and the TCU to reset and then turn on and the car wil move again as normal (for a limited time of course).
U see, this gearbox and engine is very sophisticated, unlike the stupid Malaysian Kambing Mentality that says Savvy is lousy and only Myvi is good. They dont know how hi-tech this system is. The Savvy chassis, gearbox and engine is a PERFECT drive by wire tech for small a cc. The only problem is, like the Malaysian Kambing Mentality, the local assembly line did not followed Renault's original assemble plan correctly - no way the Renault Clio would have had this problem with the Magnetti Marelli unit like ours(ours is made in italy too, same stuff). The gearbox of savvy is very solid, and does not stutter like Myvi MT at all, and the AMT is a very good module that actuates the clutch more precisely than a human. If it jerks and stuttles, it only means that something is wrong with its assembly into the car, in this case, the wiring. So if something that is not meant to jerk, stuttle and jam, start to give these problems, it means that someone is not following the intructions when assembling. In fact the AMT unit is so hi-tech that it PROTECTS the mechnical parts from spoiling by temporary disabling the gearbox or preventing gear change, which is less dangerous than the car actually failling. And after so long running in a deprived state, the AMT still works - that is a rather good job by Renault, only thing is stupid proton dunno how to assemble, they think that hi tech western cars deserve cheap ass mentality to understand and can simply 'pasang'.
By right, the warning light isnt supposed come out at all, not even for one second. If it does then somethings not right and it deserves to be rectified immediately. Anyway, I dont think renault ever made such a faulty thing. Its should be a proper smooth semi-auto clutchless manual. (FYI, tiara is not Renault so stfu and go eat kambing -[ censored ]- bashers) (AND NO, they do not share this engine, D4F is strictly Renault, and Savvy doesnt have any engine problems except fot the ignition coil) (And NO, the Citroen failure model is not one bit its predesccesor, you stupid mindless bashers who say things based on gibberish word of mouth)
So one good way to solve this is to stir up the pride of Renault by telling them that Proton is 'mis-assembling' their parts and causing thier hi-tech gearbox to give problems as though it were a junk, creating a bad impression of Renault within the Malaysian Kambing Mentality market as well as the south east asia region. This will surely get their attention. Maybe someone should go tell Quincy Govin.
And the problem here is actually not the oil as i once thought and the gearbox is still doomed to fail if the MAIN PROBLEM is not rectified. The wrong oil type only aggravates the problem and will help a little if you change it.
My take on this scenario is that, somewhere, something is wrongly grounded causing voltage problems. Or proton took the wrong voltage reference when grounding. Or something is partially short circuited. Or a voltage regulator of some sort is missing from the gearbox electrical system due to cost cutting or who knows what. Not oil, not clutch pump, tried all that and wasted enough money already so y'all dont have to waste that kind of money like me. Take my word.
i am shocked!
remind me of this 2 things happened to me:
1. once my gear did stuck at gear 3. jammed! in hot blazing afternoon 5 mins after i start my car n drive off for lunch! send to proton sc they only clear the log n reset ecu tcu
2. when switch on aircond at (speed: 3/4), when changing gear can heard the fan turn slower like not enough power. or at night with all lights turn on, aircond at speed 3 or 4, when changing gear can see the light will dimm and wont bright enough temporarily. like not enough power to draw from battery or enggine.

btw, my aircond not as cold as i first got my car. aircond gas not enough? is there anyway to chk it without sending to aircond shop for refill?
