I just replace all discs in b1b2b3b4c3 packs along with resealing all pistons. C1c2 was the reason of failure they were completely gone and there wasn’t much to salvage so I ordered reman. Ran the tractor for the spring work transmission filter plugged once now it is over heating in about 1.5hr 190degrees oil is still black I have flushed it twice. Started to check pressures the reverse gears are checking out good as soon as I go into forward gears my lube pressure drops to 0 and system pressure drops 10 psi in following the it book not John Deere any help would be appreciated. I have removed shift controller and found the transmission override engagement pin in the elbow sticky I had to work with it to remove. Other than that just dirty from first failure I hope any how
