john deere 310 se transmisson problem

My neighbor has a 1997 John Deere 310 se. One day it lost all hydraulics and forward and reverse. The dealer said the torque converter failed. The service call was going to cost more than the machine is worth so we pulled the transmission back. It was fairly easy. There was a small amount of metal in the splines of the converter but not a lot. He took the converter to the dealer to have them check it out and the said a bearing collapsed inside and sold him a re manufactured one. We put it back together and it work for about 30 seconds and quit again. Turns out that some time before he bought it, the transmission was removed for some reason and when it was reinstalled the did not line up the pump shaft on the splines of the torque converter and pushed it into the transmission pump. The pump shaft was only engaged by about 1/8" in the torque converter splines. He has owned the backhoe for about four years with no problem until now. It striped the very end of the splines on both the shaft and converter. Any way we got that fixed and the hydraulics work fine. However the machine will barley move forward or in reverse. The transmission fluid was foamy so we put new o rings in the transmission pump. The fluid is not foamy any more, but it made no difference with moving the machine. Is there a chance that the re manufactured torque converter is defective or did we miss something. We only pulled the transmission straight back and put the converter is and went strait back in. Where it failed there was no room to take the transmission out from under the machine. We never touched the valve body or solenoids.



Thanks,
