'01 E430 transmission issue

[pmizell]

Hey guys, I got a scare tonight when I reversed out of my driveway. The shift to R was pretty harsh ... backed out and put it in D. The tranny would not shift out of 1st and I noticed the gear display showed N even though I was in D. The check engine light came on and I immediately stopped.

I could not move the gear lever any higher than N and I could not remove the smart key from ignition.

Went and got my code reader and pulled these:

P0300
P0303
P0304
P0705

I know the 1st 3 are misfires but the 705 (Transmission Range Sensor Circuit malfunction [PRNDL Input]) has me worried. No unusual sounds coming from the tranny.

I cleared the codes and everything returned to normal, but I'm playing it safe and not driving it until I figure this out.

Any input would be greatly appreciated!
