Possible Solenoid Problem? Very experienced, Please help

[Dexter16]

Hello all. Short and simple.

Rebuilt the transmission due to worn snap ring. When rebuilt, valve check balls were in incorrect positions. Burnt out overdrive gears down to metal.

Ordered entire new set of clutches and rebuilt the entire transmission again. New clutches, New snap rings, new filter, and CHECK BALLS IN CORRECT SPOTS.

Newly assembled with new fluid, the vehicle and transmission drive fine in 1st and 2nd gears. When I get to speeds where 3rd (direct drive) would be needed, it bounces the rpms, tries to enter 3rd and simply goes into 4th. As soon as i get over speeds of 20 mph and need to be in 3rd or 4th, my transmissions temps go from the normal 105 degrees to excess of 180 degrees.

I know that everything internal is in its correct order. Ive rebuilt this tranmission so many times I could do it with my eyes closed. I also even went out and bought a service manual for it to see if there was anything I was over looking. All is good.

After doing countless hours of research I believe it may be my solenoid pack. The only reason I believe this is because that is the only thing I didnt replace after having 6 clutch disks worth of material floating around the transmission.

Would a bad solenoid pack affect non engagement into 3rd? Why would it be overheating?

97 PSD E4OD
Rebuilt cause of destroyed 3rd gear clutches
repalced all clutches and filter
did not replace solenoid pack

Any help would be extremely useful, I need to move next Wednesday and drive 580 miles from PA to RI and I am in a very bad situation right now. Thanks in advance.

did you flat file your valve housing,or make sure it wasn't warped at all from heat?
