Powerglide damage from 'clicking' engine off in lights

Kevin Panzino · 08-02-2013, 11:49 PM

Guys, its a forward pattern powerglide, so there is no "clean neutral' valve body, nor a need for one... Yes I understand the implications of accidentally hitting reverse at trap speed. I have a very good reverse lockout shifter, which requires a second lever be pushed to engage reverse, I use nylon locknuts on my cable linkage, and I dont 'slam' it into nuetral, I lightly slide it forward.... All that is OK.

What I am wondering and asking about is how the guys who click it off in the traps are keeping the glide from damaging itself, when the engine stops and thus the front pump stops, so there is no forced trans fluid/oil flow through the assemblies at 8200 + RPM...

Bill, I had heard the same thing about the accumulator, but I thought it through, and you could arrange a check valve and orifice setup, such that when the engine starts the full line flow back to the accumulator is blocked by a check valve, but passes through a small orificed bypass line, so it charges very slowly and it wont cause a delay in building engine oil pressure. Now when you shut the engine down and the accumulator flow reverses back to the engine, it does so quickly through the full line size through the now open check valve....
