If there is a wide range of pressures with throttle from near idle to wide open.. Look at the filter relief valve..You can see part of it from underneath when you take off the vertical transmission filter . On the side of the case ,remove plug inline with relief valve. Pry , scoot valve out of plug hole..You will find a spool and spring with a poppet inside the spool.. Look closely at the position of the poppet.. If it's not completely on it's stop, it's leaking trans pressure oil back to sump.. It doesn't take much at all to stick the poppet.. Just a speck of crap is all.. Put it back together and try it...
Thanks for the practical info. I have a gauge plumbed into that port at the moment. Pressure doesn't vary much, 60 pounds plus or minus a hair unless I shift it, then it drops to 0 momentarily. Will check that out, there was lots of crap in the hydraulic system. JDparts shows that valve but not in reference to any other parts so I had no idea where to look.
