I am having issues with my DG auto and, on looking around for a kit to enable a rebuild, I keep seeing notes that the mainshaft seal is no longer available in the kits. As this seal is likely the cause of my problem (long delay moving up to third) I am left wondering how to approach this. I am considering - but not keen on - installing another model auto with more readily available parts. If I can’t get parts for the original box there seem to be few other options. I have two other DGs available, which are likely from MK2s, so I was also considering installing one of these to see if it’s OK, but I would need to know whether these are easily interchangeable. Any input welcome.
