Hi guys, just need to vent, and hopefully some help. After weeks of part time gathering info, parts, a large bearing separator, finding a 13" disc, I final got my trans rebuilt. Installed rear main seal, farmed out my good flywheel to a machine shop for the pilot br upgrade, only to learn an employee pressed the bearing out the back of my flywheel !! I was trying to use all the TDR advice and upgrades and was very careful assembling trans so as to only tear the Dodge down once.

#1 getrag was quiet an worked pretty well, just wanted to inspect brs. Found brs OK. Surprise was Rev. OE sync brass was separated and paper thin ? Yet worked OK. I replaced 2,3,4, Rev. sync rings with after market. 3,4,R, being solid brass. Used orig shims, which made it snug, but no tighter than getrag #2 I just pulled apart with over 100K on rebuilt.



PROblem: while still on blocks, and only few secs at a time, I ease the clutch out and a rapping sound comes from cover. Remove cover and do same test with starter an see no problem or noise ? New oil had fair amount of brass for 2 min or less running. Forks already had normal wear so can't tell anything there. Belive I assembled it the way it was as I have before photo's.

One clue: this trans has lines on sync's going forward, while trans #2 has R-5 syn lines towards rear. Which one is right, or doe's it matter ? All new an used sync rings are loose fit except R brass ring which moves with a little pressure. Maybe this new ring is trying to wear like the old one, causing fork to knock ? Rather not detroy new brs pulling it down, until I know whats wrong. Sorry this is so long, 'down in the dumps Will '
 
Now what ? I pulled the trans out of truck again ( much quicker 2nd time ), pulled Rev-5th sync off expecting to find it was in backwards. No such luck ! The last rebuilder on one of these trans just put the outer fork hub on the sync hub, backwards. No wear on the new brass sync rings, yet flakes of brass in oil ? Looked in at new pilot bearing and new clutch hub while engine runs, all seem to run true. My new throwout br. has grease oozing out after only 2 min run time. Guess I will take that back.

No point in putting this OK looking trans back together until I find the cause of the Knocking sound when cover is on ?? Any idea's ?
