Engine/Transmission (1998.5 - 2002) Auto Trans Pressure

[mberry]

Anyone know what the pressure is going through the transmission cooler at idle and in neutral? Thanks everyone.

In neutral I am pretty certain there is no pressure. I say this because when I do a complete fluid change I pump out the fluid from from the line to the cooler. Put shifter in "D" and it pumps fluid out. To stop fluid from pumping while you top up pan, put shifter in "N"

I thought it pumped in N but not Park? Okay then, how much pressure in any gear??





I know it pumps in D otherwise you wouldn't make it to the end of your driveway unless it is downhill.

I should know this.

I do believe my current line pressure at idle in gear is 65 psi.

I think stock is about 40 psi.

Thank you Scheibins! Now, any idea of the flow rate? Anyone? Beuler? Beuler?

My bad stock is 65psi. No idea on the flow rate.
