350 trans. leak

my th350 is leaking fluid out of the speepdometer shaft area, which obviously is a rubber o-ring problem. there is an o-ring around the shaft which houses the plastic gear stem, but is there supossed to be an o-ring around the plastic gear stem too? I cannot determine yet if the leak is coming out the cable end or at the opening where the stem shaft goes into tail housing. This is a new overhauled trans. and the o-ring was new around the metal shaft going into tail housing. Thanks

There is a lip type seal inside the aluminum housing held in place with a cir-clip ring and the o-ring is around the OD of the aluminum housing it runs in.

hi, you say there is a lip type seal inside the tail housing and the o-ring sets against the fixed lip seal? Is there any photos available of this setup and also are you saying there is no seal at the plastic speedometer shaft inside the aluminum bullet looking cable housing? Thanks

db ....

IF you have an aluminum speed-O bullet the shape and size of the unit on left in foto by Cole.... throw it away and purchase a steel unit as the left in foto.

Aluminum bullet is worn out by the plastic gear. If gear is worn , replace it too

thanks for the photo and info guys. The photo on left seems to have an almost seal looking image around the plastic gear shaft, where as the one on right does not. Is the one on the left the steel one I should get? Thanks.

Never know... my typing skills are poor and sometime I leave words out. The folks here usually catch that for me
