Been rebuilding my TH350. B&M Transkit. Thanks JT. Down to the final steps and have encountered a prob. You're suppose to bolt the oil pump in place and check for end play. The spec is .015 - .030, mine is considerably more. The instructions say 'get a thicker thrust washer from your GM parts dealer to adjust to proper end play'. All the GM parts places I've called say 'huh?' 'A what?' Anybody know where I can get a thicker washer?
