Hi all, my TH350 is leaking fluid at the speedometer cable housing. The housing is only held in place by a single bolt and washer on one side which is causing it to seat unevenly. Am I missing a part that would allow the housing to seal equally around it's perimeter? Also, since I'm not even using the speedometer cable could I just remove the housing and block it off? I hope this makes sense (it's early). TIA
