Corrosion on trannys where salt/anti icing stuff is used is all too common.
There are many core tranny's I get that have totally unusable cases due to
that problem and there is nothing other than painting when thay are still ok
that will stop it.
Once the alloy is starting to go, there is nothing permanent that will help
that I know of. JB weld will temporarily do the job, but wont stay put for
long. Some guys have added steel pieces onto where the shifter mounting tab
goes to jury rig it, but you have to have enough material there to hook the
plate to....no easy answer..
