I am very upset. About 3 weeks ago my tranny started shifting rough, making me a tad nervous. However, i didn't think much of it, and kept on driving. One morning i was coastng at 30 mph when my tach suddenly dipped from 3K down to 1K like a brick, but immediatly went back up. The whole car seemed to drag during this dip, but quickly returned to normal. Once again, i shrugged it off, hoping nothing was wrong. The rough shifting did continue, so i decided to see if i had any trouble codes. Nope, nothing there. So, i changed the tranny fluid. Still shifting rough. Friday i was driving along when the tach dipped below 1K again. However, this time it did it 7 or 8 times. By this time i know something is wrong, so i bring it to a dealer. Immediatly they say its the tranny, and they would plug it in and let me know on Mon. Well, today they called said i have no trouble codes, and did a full diagnostic on the tranny, and they drove it for over 30 miles, and they say it drives like new.
I KNOW there is something wrong with my car, so they said that the head mechanic, who lives 40 miles away would take it home and see if it acts up. If they don't find anything, what do i do? I think it may be a fuel injector, or fuel filter, or even a TPS, because the tach sometimes dips when im idling, and i have been getting pretty bad gas mileage (around 20 at best) Also, my cat stinks sometimes when i go up hills. So, i have no clue what to do. The car only has 45K on it. It is a 1998 SE, v6. So, any ideas? Does this even sound like a tranny problem???
