when it rains it pours, I seem to be having a bad spell with my transmission lately, first the chirping sound (bearing) now a sticky shift stick.

here's the scenario.

after driving a few kilometers I noticed that when I shift from 3rd to 4th, ang ganit/kunat ng shift stick ko, 3rd to 4th lang.

I don't have crunching gear sounds and the clutch is not slipping, it's just the shift stick maganit going into 4th.

I haven't removed the center console and the shift boots to inspect. I'm suspecting the following: worn grommets, bad shift linkage, or a bad gear oil.

I included gear oil because only after the car has driven several kilometers (nakapag circulate na ng husto yung oil sa tranny) does this "maganit" thing comes out.

I want sana some other opinion on what could be other possible cause of this "sticky shift stick" before I start removing the center console, which is a PITA.

Thanks very much
