He might not have done that test because he didn't think it necessary at this point or being his garage was full. If I remember right the port is pretty difficult to get at, under the throttle body below the thermostat area. I'll look tomorrow in the daylight to see how accessable it is. Maybe the air intake box has to come off? I will keep your suggestion in mind for sure. I will post on this.
Do you use a oil pressure test guage or something different? What pressure is considered low? 20psi 10psi 1/4 NPT fitting I think....
I will have to go to the library and look up the procedure on Alldata for a better understanding, hey they got diagrams...but you know that. I have online access to some repair info but not as refined as alldata.

transmision pressures are around 120 psi area with these type transmissions. this is how to test a transmission for proper operation.
every one will have a testing proceedure and the pressures expected. this is done on the lift .
