turns out its the forward modulating valve. I did a preasure test for forward and reverse. forward preasure was spec 105 + at idle but when shifted into neutral, still had 50 psi. took the valve apart and found a small spring broken. thanks

you should naturally run the normal checks of changing the filter and 'last chance screen', also take pressure readings, and you could disconnect the wires to the solenoid actuated modulator (selector) valves, as part of the check, to make sure it is nothing external, but my bet is you going to want to trade this truck in, I think it has a bad clutch pack in the forward direction.

Fact of the week
According to studies published in the English Journal of Medicine, the impact of daylight savings is revealed by a 24% increase in heart attacks on the Monday following the spring shift forward. When clocks move back in autumn, heart attacks drop by about 21%, suggesting that loss of sleep is an important driver.
