Hi people I have a problem with m20b23 ... I bought it 5 months ago, with gearbox and everything else, but I began a search for a starter failed and when scraped pallets ... m20b25 finally took off the starter and flywheel yet happened. turned out .. gearbox is getrag240 which is not at all ... I bought a box of M20 zf removed from M20 but still did not work ... anyone have any idea what the problem is ...?? I apologize for the spelling, my English is bad...:stupid::stupid:
