Sorry guy's for not posting sooner, been having
computer problems, have had the transmission out, and
apart, cannot see or find anything out of the ordinary,
as being the problem, the line pressure is 155 lbs, and the
valve body is a turbo action with a brake, but I don't use
the brake, no lba, when the problem occurs, it flairs so
fast the air shifter will shift the transmission into
2nd gear, you're a sitting duck then,it still pulls when it shifts,
and there is no consistent time it does it, but it seems
to happen when it starts to get some heat in the traansmission,
but it never gets over 200 degrees, I am baffales as to what is causing this problem, it is something that has just started happening
recently, out of ideas?????????????
