Changed 2nd sets of solenoid, problem also appear, no jerk, but during shifting from 2nd to 3rd gear, move abit, gearbox error appear. Kinda soft of gear slipped. It happen only early in the morning, after the error, restart the car then error gone. Then afternoon time, driving smooth, but middle of speeding, you can feel a little resistance during gear changed. I tried these for about 2-3 weeks. Finally, until the error can't disappear, then, i have no choice, so overhaul the whole gearbox at RM 6.5K, i left car about 1 month to fully test it. After collecting back, it's smooth like a new car....i think still can drive for another 5-6 years....hmm.. mileage of the car is 195K during car collection (I'm not sure is this the genuine mileage or being tampered by previous seller) :68:
