<VV> Towing A Powerglide

[Smitty]

Smitty Says  ;  I have flat towed PGs many times in close proximety of my 
home, say within 35 miles at highway speeds without problems.  Twice I flat 
towed (200 miles and 1000 miles), and overheated the fluid badly.  In one 
case the tranny got gummed up and failed to shift correctly, but after a 
couple of drain and refills in three days of driving it went back to normal. 
When I say overheated I mean the fluid was cooked brown.  Yes it is true 
that the rear pump is running and circulating fluid.  The problem is though 
that the converter is not spinning and creating a centrifugal blower to cool 
the fluid.   The fluid just circulating through the pump and valves builds 
up heat.  You can get away with anything sometimes but you can't always get 
away with everything.
