A thought on using AL4 rebuilt white top solenoids. When a white top is replaced with a black top, the ECU is normally reprogrammed because the pulse width modulation frequency is different . So they shouldn't be mixed.
Ok now what happens when you have black top solenoids with a reprogrammed ECU, and replace them with modified outdated white top solenoids?. Now my understanding is the solenoid coils do not get rebuilt/replaced during the modification, so the P.M.F would be the same as a standard non modified white top.
So should the Ecu be deprogrammed accordingly to ensure the correct pulsing of solenoids ev5-ev6, before and after gear shifts, at the correct speed and duration.
A lazy Sunday afternoon's musing. So much to do and so little enthusiasm.
