problem with automatic shifting ( video in )
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

in here at 21 sec the rpm sudenly drop and shift to the third

here at the 13 sec i just release my feet and shift normally and i could continue to highr rpm
so please what the hell is going on !!
plus i just rebuild the trany
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 !

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

1-2:5900
2-3: 5700
3-4:5700

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

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
