Tranmission Upshifts to 4th gear at wrong (low) speed
Posted: Tue Jan 27, 2009 11:54 am
Hello,I have 05 Vibe base model, has 45K, recently changed the spark plugs, and transmission fluid along with the engine oil (Mobil1 Extendend Performance 5w30).The problem I am experiencing is that, the transmission shifts up to 4th gear very quickly, so underpowered engine has a wierd noise, once I push the gas, the car becomes normal. If I lowered gas, it keeps the transmission at 4th gear, does not downshifts.What would be the reason of this issue? I appreciate for your feedback. thnx.
