It had been a while..(50000Miles) since my last trans fluid filter change and my car is feeling like it eaither isnt grabbing or isnt getting enough fuel to get the rpm up to shift. When my car warms up it seems to be fine.and right when it starts. Inbetween its bad. I was thinking the 02 sensor could be the culprit making my car run to lean and that could make it not get power to shift.. and sometimes the 02 when cold or HOT will be ok? I have time to do this tommarow and maybe you have another idea...
(PS) I did change my trans fluid and filter and got the thumbs up from the dude... he said everything from there looked ok... no metal or anything...
