identification of component used in auto trans ecu ....

[mark krawczuk]

hi , i have a auto transmission ecu , and i am trying to id some
components , they are bolted to a heatsink and have :

a T on it , and 8c written in tiny letters , then under that it
has 8055P


written on it , also has 5 leads coming out of them , and i am pretty sure
that they control the shift solenoids for the auto transmission.

also in the ecu is a component labelled B946 .


any info or where to get the parts will be appreciated.
thanks,
mark

It might be useful to know what nationality or make the ECU is aisin
denso delco Bosch etc. and its approximate age. They're probably high
side switches.

hi, its a AISIN WARNER ecu. from a 1988 holden jackaroo . the number
on the ecu is : 8 94460 647 0
