On the LH overdrives, there are two types – the black label and the blue label. Are these interchangeable? I have a 1972 OD transmission (dipstick) but the OD is the newer blue label. Will this actually work? It does not at present and my next step was to check the oil pump (need to fabricate a tool to get the plug off).<o:p></o:p></p><p class=MsoNormal><o:p> </o:p></p><p class=MsoNormal>The story – I took my OD (with black label) to a shop near Portland, OR. They could not replace the clutch disk so opted to just fit this blue label OD on – which does not work currently. That was their fix after the transmission sat in their shop for several years so they didn’t charge me for it. Everything works except OD.<o:p></o:p></p><p class=MsoNormal><o:p> </o:p></p><p class=MsoNormal>David Councill<o:p></o:p></p><p class=MsoNormal>1972 MGB<o:p></o:p></p><p class=MsoNormal>1964 MGB<o:p></o:p></p><p class=MsoNormal>1967 MGBGT<o:p></o:p></p><p class=MsoNormal><o:p> </o:p></p></div></body></html>
