Hi Bill,
as far as depotting goes, I found the best method was by slowly melting out
most of the tar with the tranny upside down, lid off, chicken wire to
restrain the core and a heat source against the upturned base of the case.
When the tar had stopped dripping, I snipped the wire connections and, using
oven gloves, lifted the core out and dunked it in a drum of mineral turps
(aka "white spirit") while still hot. I left this overnight, and ended up
with a very clean depotted tranny ! :^D

Regards

Chris
