<VV> Lockup Problems Re: more PG vs 4spd thoughts

[Harry Yarnell]

The problem was (is) a sticking pindle in the solinoid. Heat makes it worse.
Putting a switch in the circuit would do nothing; the problem was 
mechanical.
Not sure how widespread this problem was, but quite alot of 125c transaxles 
suffered from this ill.
Solinoid was redeigned and fixed the problem.
