Hi guys,
Just after some advice about welding an endcap back onto a solenoid (from an auto gearbox valve body) ?
Obviously the solenoid has a thin coil of wire inside it - am I likely to induce any high currents if I reweld the end cap back on that could damage the coil. It would be removed from the gearbox, so the coil would be open ciruit (or would shorting the coil at the connector help) ?
I'm considering doing this as the gearbox (Aisin Warner AW55-51) is jolting on 3-2 downchanges and slipping on the 2-3 upchange - a known problem due to the bushes in the solenoids that the armature slides in getting crud in them. The fixes are either a whole new gearbox (3k-4k), a new valve body (£550), new solenoids (about £250), a repair kit (about £90 from the US - which is basically a drill bit to clean out the bushings and some new end caps to press on). It seems to me I can just grind off the end cap, ream out the bushings with the correct size drill bit then spot weld the end cap back on.
What are your thoughts ?
Cheers,
Tim.
Attached are some pictures from using the repair kit on youtube.
