I picked up my 60 last month and have been in the process of chasing/ fixing leaks. My latest one is coming right out of the top of where the shifter mounts. After removing the boot and unhooking the shifter, I came up with a plastic type seat and a rubber gasket. None of these items appear to have excessive wear, however trans oil is going right by them and running down the case. Oil level in the trans is full. My engine is a 2F to a 4 spd. Anyone have thoughts on this? I appreciate any input. Thanks.
