I can go in reverse and park, but when I go into drive, the car just sits there even if i were to floor it (I didn't actually do that). To make it drive I need to cycle through park, reverse and drive and until drive actually work. I checked the transmission fluid and it looks like it may be too high but I've had the car for about 4 years and never changed/added that fluid.

Check your linkage. It's possible to have a worn linkage bushing.

How many miles on the car? When you have it in Park can you push the car and move it?

If your car (an automatic I assume) has more than 140K on it figure the clutch packs are burned and you will need a rebuild on the old automatic transmission....even with proper maintenance that's pretty close to the life span of an automatic...

Well not really, most of my crap in my sig has well over 250k on the original trans.

He could simply have a clogged filter

that could very well be..no question...but I doubt it...that would be great though...shift linkage bushings....indeed....don't think so....no

I'm not understanding. You say it does drive, but you have to do some shifting around first?

Not really, average lifespan for these transmissions seems to be around 250-300k depending on how they are treated. My dad's both have well over 300k and are doing fine....my brothers 300D is at 234k and is fine. My 300SD had something break inside at 281k....I finally opened it up today and found clumps of clutch material in the pan as well as a fairly large piece of metal! :eek: Its toast....but I found/have a replacement. :D

No I can't move it while it's in park.
It's got 166k miles on it now, 142k when I bought it.

Also, is this thing still drivable? What do you guys mean when you say it can go while I'm driving, like, drive will just working when I'm on the raod?

Sounds like a B2 piston issue.

I would check into that as well as your linkages.

See links for more details.

B2 piston gone!
 

Look like your B2 piston is gone!

When I put it in neutral from reverse to check the tranny fluid it would stay in reverse. It stays neutral when i shift to it from drive. And the tranny fluid is fine.

After 4 years of never being changed?

Now it's sounding like a linkage and/or bushing issue.
