2590 power shift need HELP!

Ok guys we have a 2590 case at work. Came in complaining of noise like grindingcoming from tranny area. We split tractor and found planetary carrier was wore around the bearing supporting it on tranny shaft. Replaced it and while there we took apart the clutch packs to check plates because c4 was bad didn"t find any others bad. Put it all back together and drove today and power shift slips in 1 and 3. Determined according to I T manual that c2 clutch pack not working. Checked pressure and had full pressure at check port. Whys it slipping and where do we look next? We didn"t rebuild pistons on clutch packs didn"t take them apart either so don"t think the seals there would be leaking. Any help greatly appreciated thanks Justin.
 
Justin, if the PShift did not slip in those shifts before it was disassembled would lead us to think something was done during reassembly that might cause that problem. It has good pressure in C-2 like it should you said. I would be inclined to think perhaps when the plant. carrier was reinstalled that not all the C-2 disc's were engaged properly. If one would be caught on the outside it would keep the piston from putting pressure on the clutch pack there by causing slippage and yet the hyd. pressures at the test ports would be correct. That would be my guess. To remedy the problem you have, I'm afraid you will have to take it back apart and then you will see for sure what the trouble is. Rod.
 
Thank you Rod that"s two case mechanics that gave me the same answer. And it does stink but that"s how it goes sometime. We were worried about that when we put it back together because we did it with out the wires. We tried making a set but didn"t have much luck with them.
