<VV> Powerglide fix: TransX versus Chemtool B12 in a pour can

[Larry Forman]

Yes!    Like magic.  Except that you likely will need to drain a pint 
out and doing that is a little difficult to get enough but not too much 
drained.   If you drain too much then you might need to add a little 
tranny fluid with the Chemtool B-12 to bring it up the the full line 
when the engine is running.
