why is it that no body can help me with my probs.

Cause I have a 5 spd.   I will check for a TSB for ya though. 

I actually have the same problem, but IT IS WINTER..... and I do need a tranny fluid & filter change(it's been 30K since I got my tranny).  Once my tranny is warmed up and I've been driving it's not a problem.

This is a possibility for you however its really hard to know for fact what the car is doing
when I dont get to test drive it,,, Your car also has a lk up converter,, the stock converter
is aprox 2800  to 3000 stall,, ( of course your motor dont make enough torque to stall it
up to that)  When the converter lks up since it such a slippy converter anyway its much
like a actual shift... However your car is programed to not allow converter LK up until
a certain engine temp is met, usually around 140 to 160 F*   When its colder out side
it simply  will take the engine longer to get 140 or 160F* and simply put, you may be
mistaken LK up converter  with shifting into overdrive,, Dont be offended, I see this on
a weekly basis at the Transmission shop where a torque converter is broken and cant
lk up or Ive had a couple time where a engine thermostat failed in the open position
and the engine in the winter never gets to 140 but the complaint is it dosnt shift
into Over drive... Hope this helps, it may or maynot be your case,,, Have any questions

There is TSB for shifting when the fluid is colded. I don't know how cold it is were you live? But if you'll driving in snow, you only get the 1st,2nd and 3rd gears. Is the ck engine lite on. If not I would do a trans flush with ATF + 4 and replace the t-stat too. your engine could be running too cold too.
