I bought a 93 GMC sub that has very little rust on the skins. I got to driving it for a bit and looking into the small motor issues, but at 56 miles the tranny pump whent out. I verrified that by going down the check list and yup, the fluid lvl dosen't change. I was just wondering since I must change the pump, I would be smart to do a rebuild on it. But are there any issues that a pump fragging that should be looked at ( IE: damage, steel going where it should not go, Ect). It is a 1993 1500k 4WD GMC Suburban with about 251 K on the odometer. Any help or ideas would be greatly aprecatied. Sorry about the Coors spelling =)
