I've just changed the auto tranny oil (5 litres). Now it felt slightly better. But the jerk is still there. and Sometimes it tends to shift from 2nd to 4th straight away.
And just few minutes ago, it didn't want to change gear and went to neutral. Had to wait for a few moment before it decides to slot in a gear. :banghead:
Sigh maybe i should just splurge and convert it straight away to manual.
hey bro,
i solved my problem by change the solenoid. here's the story:
i went to the workshop and at first i asked the pomen to change the gb speed sensor(pulse generator) and shaft seal like this guy solved his problem
http://forums.bimmerforums.com/forum/showthread.php?t=724430.
then the pomen said, he want to scan the problem first. i said its ok but i already scan twice before this. same error appeared, error 100: gear monitoring problem.
he continue the scan and still the same error came out, error 100: gear monitoring problem.
he said gear monitoring problem is not the speed sensor problem or shaft seal problem. gearbox need full overhaul or change with other gearbox. same exactly like 2 pomens i already met before. both them also mentioned the same thing. need full overhaul. its not speed sensor or shaft seal problem. so this pomen is the 3rd pomen i meet(means 3 different workshops).
but i insisted him to change the speed sensor and the shaft seal. and again he said its not the speed sensor problem because it doesn't show on the computer during the scan.
after that i asked him, can it be the solenoid problem? he said it cannot be the solenoid because during the scan the solenoid error not come out.
i told him, my gear reverse ok, gear 1 ok, gear 2 ok and gear 4 also ok. only gear 3 not ok. so it might be the solenoid if we think logically la kan. but he said he believe the computer and the computer is 99.9% accurate, that is what he said to me.
i told him i want try to change the solenoid first, then he replied its up to me but he confirms its not the solenoid problem and i am wasting my money.
then i replied back, its ok i will not blame you if my gear3 problem not solved after change the solenoid. so i went to BA buy the solenoids (2 solenoids) and gasket and 2 liter of ATF oil (for top up only because i asked him to reuse the old oil because its still new). the solenoid product number is 24 33 7 537 062 and 24 33 7 537 063.
after the job done and charged for RM140 for labour, now no more jerking/gear free/hard to change to gear 3. everything is smooth for my car.
why the scanning tool cannot detect the solenoid problem? i think it is because the solenoid is half dead only, not totally dead.so the solenoid was detected not dead or ok. it makes sense because the jerking not happens all the time.
moral of the story: human's brain is much better than computer. and dont trust 100% the scanning tool. ahaks.
