drippy gearbox

["Rick Barnard" <rstirb@ispchannel.com>]

Folks,
        I was crawling around under the TR6 this weekend and noticed 
quite a bit of gear oil drips from the transmission.  It's hard to tell just 
where it's coming from.  As far as I know, this box has 105,000 miles 
on it.  It shifts fine.  I suspect the oil seal at the input shaft.  Is that 
seal 
easy enough to replace once the unit is out of the car?
                Any Help Appreciated,
                        
                        
                          
Regards,
        Rick Barnard
