DodgeBrothersEd Posted June 17, 2023 Share Posted June 17, 2023 I am in need of a good trans. Mine growls so terribly that the floor vibrates. Cant believe it still works. Link to comment Share on other sites More sharing options...
JFranklin Posted June 17, 2023 Share Posted June 17, 2023 Maybe it just needs to be rebuilt. Maybe some broken bearings need replacement. Link to comment Share on other sites More sharing options...

Cant believe it still works. Have you taken the top of the box to check it’s condition or if it has oil in it. Possibly other things either side of the gearbox causing the vibration to. 2 Link to comment Share on other sites More sharing options...
Minibago Posted June 18, 2023 Share Posted June 18, 2023 The Transmission in our cars has a number of areas of wear but is simple and straight forward to work on. The bearing in the flywheel centre holds the clutch nose. The bush in the output end of the clutch shaft holds things straight. These are all available new. 2 Link to comment Share on other sites More sharing options...
Minibago Posted June 18, 2023 Share Posted June 18, 2023 The clutch out put shaft wears on the square. This causes the intermediate gear to wear internally. This is a good shaft and a new gear (placed upside down on the shaft to show the correct fit. New shafts are available in Australia. It is this area which causes the most vibration / noise in 1st and 2nd gear. If the noise / vibration quietens markedly when top is selected then this is your problem. 3 Link to comment Share on other sites More sharing options...
Minibago Posted June 18, 2023 Share Posted June 18, 2023 The gearbox has bearings front and rear for the main shaft and originally these were open allowing oil to migrate back down the torque tube on steep inclines, emptying the gearbox of oil, overfilling the diff and unfortunately lubricating the brakes. Sealed bearings are now available and it is common practice to remove the inside cover allowing lubrication but retaining the outer cover to prevent oil migration. The layshaft runs in caged roller bearings and the shaft has a tendency to wear. All these bearings, bushes and shafts are available new from the dedicated suppliers of Dodge Brothers parts. As Matt said, it is most important to ensure correct viscosity oil in the correct quantity is in the gearbox. 3 Link to comment Share on other sites More sharing options...
Minibago Posted June 18, 2023 Share Posted June 18, 2023 As Matt also pointed out, there could be other issues, one is the rear universal joint behind the gearbox, this is often neglected when lubricating the various points and the top hat bearing cups will wear significantly in combination with the four drive pins / lugs. This wear can be considerable and will cause bad vibration, failure could be catastrophic so driving on amazed that it still goes is not to be recommended. Find the problem, fix it and enjoy the drive, Safely. 3 Link to comment Share on other sites More sharing options...
