Rep Power: 0

hi all

i have a 2002 honda civic coupe with an auto transmission, i am having a little problem with it and i am just wondering if my diagnostics are correct or if any of you ever had the same prob.

when i press the acceleration from stand still the revcounter goes to up as usual but when it reaches like 3000 rpms and up it drop back down and then goes back up then keep flickering

the speedometer just goes wild, from 0 - 140 miles in 1 second altho i would like it the car isnt actually doing it

and secondly the transmission isnt changing properly i dont think there is a prob with the transmission tho it sound ok to me

so do you all think i am right that it may be the speed sensor
