TRNW-2: 6r140 valve body and sonnax tooling

Hello all,
I am starting to see more and more 6r140s hit my bench.  I am comfortable
with working on them with great success.  I have always just replaced the
valve body with a ford OEM, but it seems these valve bodys are getting
priced to where I may need to look at repairing them vs replacing them.  I
do not mind investing in sonnax tooling that is needed to fix
transmissions.  However, I don't believe in needing to ream and oversize
every valve just because there is something available.  What are the high
wear areas that will need to be addressed if I decide to tool up and repair
these valve bodys?

Thanks Justin
