Hi Guys My Car is Toyota Premio 240/2002 1.8L 4-speed automatic tras. (Not CVT) 120K on the clock. Recently its not engage the last gear while driving. this is happening intermittently most of the time morning, and sometimes its shifting normally. If i stop the car and change the gears back and forth (P - L ) then the problem goes away most of the time. Previous owner said he did a gearbox oil change before i purchased the car but not sure about it. The gearbox oil level (engine running and Hot) is normal and the color is bright red, no burnt smell. do i need to change the oil ?? or anything wrong with a sensors or gearbox itself?? Really appreciate your help Thanks

Hi Guys, Am having a huge problem with my GDI. Rescently I changed the 4-Wheel actuator (vaccume valves as they call it) and did an injector cleaning. Since then my IO does ok on eco drive, but when I gun it down for quick acceleration, engine revs pass 5 but the vehicle never picks up. (The gear is not seems to be shifting) Before going for this repair, engine rev went down tremendously when the vehicle is idle (at traffic jams) to the point of almost stopping. The injector clean was supposed to clear it out according to the diagnosis performed. (But didn't had this problem of engine rev and no pickup. The pick up was fine.) The actuator was changed due to the constant blink of 4-WD light. The mechanic who changed it inserted the part from a pajero v6 and assured me IO and V6 has the same circuits. Also my ATF level seems to a good two three inches be above the maximum level. Any information regarding this problem? Is having a ATF level above max a problem? Can it cause any side effects? Can the new actuator cause this problem? I read in a post that "idle air control valve or your fact idle valve is not working properly, all two of these are housed in the throttle body.You can try cleaning the throttle body firet if it dont work you knpw what to do." Any comments on this? Plus if there are any similar probs post on this forum can you guys kindly share the link with me, I did a rough search but could not find a related post. Thanks.
