CL-S progression 01

iTrader: (2)

So ever since I got my trans rebuilt the first shift from 1st to 2nd. if I am at like 30% throttle or less the trans will engage like 90% smooth... under any decent accellerate it's flawless like the rest of the gears.

I'm sure it's the pressure switches cause they did not get replaced, just cleaned. and after 1000km it seemed to do this and has stayed the same ever since. It's barely noticeable. But I am anal like that so...

which one(s) do I replace.
