about to pull the tranny to do a clutch job and i thought i might as well upgrade the thrust washer. the tranny was fully rebuilt with new bearings and syncros by me about 5k miles ago. whenever the tranny is decelerating in first or second there is a loud whineing noise from the tranny. first gear it whines bad and second is not as bad but still there. NO IDEA why it does this but whatever. anyways there are two thrust washer upgrades available. the marlin crawler one, which is oem size and will bolt in and be done. OR the wes beech thrust washer which he made thicker than stock so you can have it machined down to take up slack in the tranny. i was thinking maybe wes beech's thrust washer machined to the right size will tighten up the tranny and possibly get rid of the annoying whine. both are the same price so let me know what you think.
