Hey Jake,
Did you manage to replace the corks? - I’ve just taken the transmission out of mine (28166) And I’m waiting for the glue to cure before put it all back together again. I followed the manual - relatively straightforward really - only real issue was working out what the actual parts were called according to the manual - as although there’s parts manuals for the later models, I couldn’t find one for our models. If you’re still having trouble, I’m planning on uploading a PDF and series of photos showing the steps I took.
Cheers Andy
