    Default Type 9 speedo seal question

    Has anybody replaced the speedometer seal on a Type 9 transmission without removing the speedo gear? On a Superformance S1 they have an access door in the tunnel for the fill plug but not for the speedo gear plug so itís pretty tight underneath.
    Thanks, Ron.
    What can I add to my fuel stabilizer to make it last longer?

    It’s a pain in the ass to extract the old seal without removing the tailshaft but I guess it could be done. I would remove the tail shaft housing. The gear itself can easily be tapped off the shaft and the remaining side shaft punched out of the tail shaft housing. You can get the correct plug from Chris at BGH Geartech In England. PM me for more info. I recently did this during a rebuild.

    Doesn't the Whole interior have to be taken out to do this?
