chill bro  the mines area is so big    i know none of city by the plate of bgw3327. but am surely on the lookout when am coming over to there.
i am staying in cheras but always go to the mines 'yam cha' with buddy.
talking about bad road planning; actually, the road around the mines area is quite confusing. especially the one heading to cheras /serdang / the mines shopping fair. you could stay in your line and out of sudden, the line is dead and you're either force to stay in your line or cut into other road user's line 
btw, the highway that pass through the mines shopping fair to balakong is famous for ah beng racer at night. be careful!
some driver are really a pain in the a#%!

you may need to go for an atf change. i was having the same problem too. after an atf change, gear shift back to normal. if it was already more than 100k mileage, don't go for atf flusing cuz' it may end up damaging the worn out rubber seal inside. just an atf change will do.
and don't forget to clean up the throttle body more often!

if your absorber is still working fine, changing the worn out absorber link may help. cost around 35 bucks / side for compatible and could be around 60 bucks for original oem proton. this way, no squeaking sound going over the bump.
