Hi!

When I try to park my car by shifting the gears, sometime I can't shift from "D" (drive) position to "P" (park) position, the shifting gear stuck at "R" position (reverse). If I shift the gear back and forth many times, then it works.

The transmission works fine. Any ideas?

Thanks for your help.

Next time try shutting the car off and then see if it will go to park. The problem I envision would not be the case if you are truely able to get to reverse.

That condition is the sticking of the governor. At 10kph the first piston of the governor opens the fluid to the control sector. The pressure instantly goes from zero to a few pounds. At this time the reverse interlock is hydraulically engaged and its not possible to shift to reverse.

If the piston sticks this pressure continues at a stop causing the shifter to not go past reverse till the car is shut-off.

If this isn't the case I would look for external linkage problems.

Hi! MB STARS, 190guy and gillybenztech,

Thanks for your very helpful information. Because of this precious information, I successfully replaced the transmission fluid and filter today.
It took me 2 hours to complete the task and surprisingly there is no leak.
One very important thing I want to share with everybody is that if you notice any transmission problem, you should change fluid and filter first before you start any repairs. The whole kit only costs $22.00.
I got 2 transmission problems before I change the fluid. After the change, both problems went away.
One problem was the hard shifting, the other problem was that I couldn't move the gearshifter from "D" to "P" sometime.
I even got the advice from some transmission experts to rebuild the transmission. That's $2000 at least.
The transmission runs very smoothly now.
Thanks! Have a happy labor day!
