My car won't move while in DRIVE. FML.
I tried turning it off and starting it all over again multiple times but no matter what it wouldn't go. Luckily enough my next door neighbor comes home (certified mechanic), and I go over, explain him the situation to get his input on what it could be. He said that from the sound of things it could be the shifter cable that either ripped/broke or got disconnected. Can anyone corroborate this? I mean I have faith in this mechanic but at the same time I trust the elder and wise from this forum. Please let me know what you think it could possibly be. School starts next week and I'm screwed without a car. Please and Thank You.

If it does not come right - check the fluid level in the tranny - the cause of 99% of transmission problems is low fluid.
If you have no luck get it on a flat bed & take it to the dealer to get it on a STAR DAS - They can diagnose & reset the TCU.
Good luck - Apart from fluid level check & reboots this is not DIY.
I hope this is the problem & nothing is broken.

Sorry dude..Im sure this doesnt help.
Good luck in getting it fixed though.

I guess the only thing I can do is keep the key in my pants. Literally. And thanks. I just hope Mr. Glyn is right and its nothing major.




I'm with Glyn on thinking your friend's sister tried something stupid. The only time I ever threw error codes on my car was when I tried doing stupid like donuts in a parking lot.

You can't move the shifter out of P without engaging the brake..
But you can shift from D -> N at any speeds without engaging the brake, I believe.
And you can shift from R -> N at any speeds without engaging the brake as well.
And when you're in N, I believe you can shift from R-N->D or D-N->R, but the D or R won't engage and you won't be able to actually Drive or Reverse, until the rpms of your engine go down to like... under 1.5 or 2krpms

I don't know if I'm being quite clear.
But sometimes when I accidentally shift into Neutral from Drive, and I'm at higher RPMS: 3k+
after engaging back into D
I won't be able to actually D, until the RPMs die back down
And I believe it's the same case when moving the shifter too fast, D-->R, and R-->D


Regarding the interlock. This is where cars differ. On SA cars it's all electronic - on Ed,s early Coupe there is a cable that can be adjusted purely for the interlock & not selection. On cars I am accustomed to the EIS, TCU, Brake pedal & interlock are all tied together. It's possible that the interlock has been locked out of play by the TCU. It's a few years back & I can't remember exactly what happened on my car in this regard when I lost selection.
Ed's car was stuck in gear - interlock jammed - If you have the cable you might want to check it

Take a look at the brake switch pdf. posted by Johnand & have a look at post #30 where he lists all the interlock & cable pdf.s
Good luck!

And thank you so much.
And I could use some luck at this point, and if its not that, then money!

Do NOT disconnect the battery with the key in the ignition!

)I will have to try that, but first give me your input on the pictures that are to follow....

See splinter's pics in the link above.
BTW - engine temp is not a good indication of transmission temp.

Not that I've ever tried it,.... but see how that little RED ATF Tube Lock Pin has a little notch on it close to the bottom end. That notch looks like it notches onto the outer edge of the openning of the transmission dipstick tube hole. So I'm thinking if you use one of those small electronic flat-head screwdriver or even a u-shaped wire clothes hanger to un-notch that little RED ATF Tube Lock Pin from underneath the black cap,... that should do the trick.
It might save yourself 50 cents,... yeah, I'm a cheap-skate,... who drives a Mercedes.

And if it works,... it'll save you a trip to the dealer.
