The latest is as follows....
Gearbox..... it was running smooth for abt 1 week after Vasant did a flush & changed the ATF... but the harsh shift is back...also when the A/C is on.. the car feels very heavy.....
ECU..... after all the injector cleaning, throttle body cleaning, fuel system cleaning....etc... i did a OBD2 scan... same Injector Pulse width.... so i guess what's left is to Replace both ECU & AT
