95 explorer trans code 646
95 explorer wont shift out of 1st gear unless I let up on throttle.
o/d light is flashing and has a memory code 646 ( gear 2 ratio fault) also koer code 336 (egr pfe/dpfe volts higher than expected).
Has anybody seen this problem before,or know what these codes imply?
Or how they may relate to my shifting problems? Any help would be greatly appreiciated !!!! Thankx for reading this post!!

You can try resetting the code by unhooking the battery for 5 minutes. The OD light on my 95 blinks about once a year. When the light is blinking, the trans goes into cripple/limp mode and causes hard shifting. I've pulled codes to no avail. Resetting the code puts my light out and trans shifts fine. Needless to say, if your light comes right back on, you need to look further into it.

The guy already has a confirmed symptom, so resetting coes won't help out.
I bet the tranny code is for a bad shift (1st to 2nd) shift solenoid....but you ought to look into getting that DFPE tested (Haynes manual should have specs) before you even think of replacing it.
If I had the time, I'd google for Ford OBD2 code 336 (you need FOUR digits for OBD2 codes, though...), but now you know what to use to look that code up.
