Trans stuck in 3rd????
So I took the car out for a ride today.
I threw a code P0121..Throttle Postioning Sensor. I replaced it a couple weeks ago but I have only driven the car maybe 3-4 times.
First off, I have a 3500 Fuddle and the trans is vacuum modulated.
Anyway..I was pulling up to a stop and the car died. I restarted the car and the trans feels like it's stuck in third. I say that because it feels like I when I pull away from a stop the car revs(like a normal car with a loose converter) but has no power. It never shifts..and then when I cruise at 60mph I am at 2500 rpm's...The car is shaking real bad too at a stop sign...worse than normal with my cam(236 @ 050 .585 lift).
Any ideas???

man that sucks, hope you get it worked out. It may just be in the trans, did you try manually shifting it to see if it would come out of gear? sometimes my car will not downshift even under wot. it is weird, it will just sit in third gear and try to pull. Looks like we both may be looking for an answer. m however if this is the case I think it is a computer issue rather than a trans issue considering I just put a new trans in my car, but it still acts up occassionally.

no, I havent tried dropping it into first...too late to take it out now. I will take it for a ride in the morning and see it it make a difference.
My trans has less than 1k miles on it too.

check to see that you have the p0757 code shut off. I had the same problem you described (being stuck in 3rd) right after i put my 3,800 fuddle in. Thought i toasted the trans.. If the computer see's the converter is slipping too much (still thinks the stock one is in there) it will set the p0757 code and lock you out of certain gears, for me it was everything except 3rd. Do a search under my screen name and look for p0757
