Hi eplummer,

Sounds like you have solved the problem. A slipping 3rd gear unit, 1-way bearing.

To prove it, have you locked up only the 3rd gear clutch? Since doing only this, will isolate its associated 1-way bearing. Allowing you to test 1st & 2nd gears without the suspect 3rd gear shift units' 1-way bearing influencing the result. Obviously your gearing is going to be way different to normal - as you know, much taller!

I realise you said, you locked the 2nd & 3rd gear clutches together, & all worked fine, but what happened when you locked 1 of them at a time? Thus isolating each 1-way individually!
