Manual first pressures are low after going on a drive.

[Warrant]

Ill try to make this one more simpler since I think my last post was confusing.

After I take my newly rebuilt 700r4 on a good drive around the town, (warm it up real good), I stop with engine idling at about 650 rpm's , and put it into manual 1st, my pressures read 70-90psi.

When I first start out and do the same thing but with only 5 minutes of driving my pressures read 210psi in M1.

Is it just because the idle is low when warm? and I have idling higher when its cold to keep prevent the engine from dying?

Doing a standard thorough pressure check the pressures all look good

Does this sound ok?

Thanks

What do you get if you run it up to 1500 rpm?

If I hold the brake and bring the rpm up, the pressure instantly rises and if I recall correctly it is just barely to 200 psi around 1500RPM. (TV hooked up normally)

Driving M1 2000-3000RPM pressures are back up past 200PSI.

Probably a little too much clearance in the pump.

is it going to muff things up?
