so when i run the engine and drive the car normally, the 2-3 shift is very wierd ! when it shift from 1-2 into 2-3 the rpm just goes up without stopping until even 5000 rpm and wont shift to 3-4 ! a guy said that it could be the tps.... so i changed it but without any difference !

there`s 3 things happend in the 2-3 shift..... when it wont shift and still going until 5000 rpm and i realese the pedal and it shift normaly

or when i keep my feet on the pedal it keep going up...but when i hit it , it shift normaly

and somtimes when the rpm goes high it shift fast and the rpm sudennly drop

and the car was tuned before

sorry for bad spelling ! and if there is any thing u want me to explain more just tell me !

I can't tell anything from those videos, your explanation is a little hard to understand as well.

the 2nd shift rising into high rpm range without shifting to third, it sound like manual shifting....... it wont shift to third unti i release my feet from the pedal ...or it sudenly shift hard and thre rpm drop.......

Have you changed the shift points with a tuner?

MaKaVeLi

my shift point was this :

1-2:6000
2-3:5700
3-4:5700

and the only change i made was the 1-2
1-2:5900
2-3: 5700
3-4:5700

this happened after i rebuild the trany

Did you pay to have the transmission rebuilt? If so you might want to bring it back.

MaKaVeLi

but i didnt have this problem before even when the tranny was little bad, and when i check with my mechanic ( not the same rebuild shop) said that its not from the transmision it occured cuz of the tps , but i changed the tbs today and still nothing resolve

MaKaVeLi

ok i will try to expalain it more, at low speed , driving in the city, when the first gear shift in to the second, the second goes slowly to higher rpm without shifting to the third unles i remove my feet......the mechanical said the its from the tps, i changed it with no use, so its about the " air breath " or somthing like that......... im so confused :S
