Yes as said the white and brown wire is the one 'sassanach' suggests, how do they fit, are they esay to change, would a secondhand one be ok ?

ive just dug out the solenoids & looked at the wire colours, the brown & white as mentioned seems to be brown & light grey, just hope ive got the right one as all the others have nothing close to brown/white :-/ & want to send the correct one

valve bodys, plates of alloy with hydraulic oil ways machined into them. The solenoids, activated by the ecu, open and close the oil ways which activate gears clutches and stuff that sit behind the valve bodys.... afaik. So the pic only shows about a 3rd of the story. And my description probably is about a 5th of all the other stuff that goes on. Torque converters, no idea how that works, none what so ever. Seem a cut away of one, still no idea. Would love to pull a box to bits one day and see how it works, just not mine please god, finger crossed, touch wood.

Have a read here ... quite a way down, top bit is manual gearboxes, then auto's then torque converters ..

I've taken auto boxes apart and it is fascinating. Never got them back together again mind....

it is very interesting to have look into a gearbo! i have done a couple of change overs from auto to manual and vice versa but that was twenty five years ago on the mk 3 cortinas  !would not be able to manage it now
