Nissan Altima 2002, automatic transmission. 230,0000 KM. Fresh transmission fluid and engine oil.
Something clunk when I shift from Park to Drive in the cold start. The only way to avoid this clunk is to wait for 5 ~ 6 seconds after I started the engine. Then I can shift from Park to Drive smoothly without the clunk. This only happen when the engine is cold. What could be the cause?
Thank you all the Pros
One thing to add. After I started the engine for 5 seconds, I felt something engaged either to the engine or the transmission. And then I can shift from P to D smoothly.
Something is probably is starting to wear out inside of your transmission - maybe the AT oil pump doesn't supply enough pressure right after startup but it could be almost anything, or maybe it's electrical.
Ideally you could tell if it's a 2nd/3rd generation and how many speeds does it have, but generally dirty fluid clogs solenoids/ the valve body and causes a lot of wear to the mechanical components on these. Also, IMO it's just a good idea in general to wait after you start your car to put it in gear...
