Due to the wear in the pump stator central bore for iron cast rings there is a loss of connection leaktightness with the shaft , which leads to lack of the converter lockout pressure in the drum Forward (K1), or in the packet 3-4 (K3), which in turn leads to a corresponding clutch combustion. It is connected with the delayed converter repair. Also a thrust washer seat wear in the base of the stator is common, which leads to axial clearance and vibrations. It is necessary to replace the pump oil seal and bushing. If you are late with the oil replacement, and with the  replacement of oil seal and bushing, then you have to replace the entire pump assembly.
