When you say solonoid are you referring to the solonoid pack on the valve body. Have you replaced the TSS sensor? If you have, your end play in the transmission may be too great because the clutches/steels are worn. The new tss sensors are not as powerful as the old. With excessive endplay the sensor can not detect your turbin speed properly, from what I have read and understand. Unisys would have more info.
Then again, your clutches/steels may just be worn out and it is time for a rebuild. When you had the tc out you could have had it rebuilt then......
Looking up your line pressure, it looks right on. Seems oil pump and valve body are fine. replace clutches and steels along with PROPERLY CHECING ENDPLAY IN TRANS. Endplay is everything in this trans, if specs are too far out, oil will not be able to travel through planet, etc.....
I recommend
www.bulkpart.com for rebuild kits, If you are going to rebuild I recommend the master kit that has the clutches and steels....
