Have fitted the gearbox with J type overdrive from my long term project, not as quiet and the overdrive is not as smooth when selected engages with more of a thump.
Been having a look at the faulty gearbox.
Two teeth missing from the third gear on the countershaft, would I need to change the mainshaft third gear as well?.
Would the overdrive, J type, need stripping for cleaning?.
