Found problem..now what??

[Razor]

Pressure drops in second gear at wot. Doesnt drop in 3rd or 4th.

Pressure at idle in park 50-60 PSI, 200 if I pull the cable.
Pressure in 1,2 goes to 160 PSI at lite throttle, full throttle in second, drops to 80 PSI. Doesnt drop in 3 rd gear or 4 th gear at WOT.

Shifts are firm and crisp at lite throttle at proper speeds. Under WOT pressure goes to 160 then drops to 80 at higher rpms..

Suggestions..

Thanks

But I will.. Sounds like sump is being uncovered or fluid is being restricted to pump. More proboble is air or a leak in the suction side of the pump.

Thanks Pete, thanks Bruce.

I'll be trying the test with the car on jack stands..pointing away from the house .. and seeing if with the car stationary, it does this as well.

With the car at high idle, gear selector in "2", yanking on the cable, it doesnt do it.

I'll post my results..
