my transmission shifts into at 10mph, 20mph, 30mph and so on. i checked the voltage on both the tps, and map sensor. both checked out fine. i have no check engine light. i checked with a computer anyway and nothing came up. i was wondering if it could be something a little as a cable needing adjustment, the vss sensor, or maybe a possible transmission problem. have any ideas?

by the way, i replaced the spark plugs, wires, rotor, distributor, air filter, transmission fluid (honda atf), and i change my oil every 3000

i would appreciate any help. thanks

Hi ktangelbaby8,

The shifting of the trans depends on the throttle pressure so when you accelerate slightly, it would upshift fast.

There are a few specs for the trans type and if it utilises a trans throttle pressure cable, then it could possibly need some adjustment.

Let me know the trans Serial Code if you are not sure.
