Technical Th350 speedometer bullet leaking

Ok guys I have done everything that I can find on here, new bullet, new gear another new bullet new seal driven all the way into the bullet and I can not get this thing to quit leaving, what else can I do/try all the speedo bullets I bought off eBay are they junk by chance

 

are the bullets steel or aluminum?

 

find a good used steel one, put in a new seal, O ring, and gear, and it should be fine. Or see if it's really leaking from somewhere else?

 

They are steel

 

steel should work with new seals and gear-like Jim said are you sure thats the leak? Many times its the shift lever seal-have changed many

 

It is definitely the speedometer bullet, shift shaft seal was leaking I replaced it and it no longer leaks, I have this car up on a rack also and everything under around the trans is clean and only spot that has fluid is the speedo cable, I have read that some people drive two seals into the bullet but I would think I should not have to do that, maybe I will order some new seals and see what that does even though the new bullets had new seals

 

If it has been leaking from the shaft seal it could have pushed oil up the speedo cable. May take some time for it drain down.

 

Any chance your vent is plugged and the trans is now leaking at the weakest spot?

I bought a steel replacement speedo bullet off eBay (for a TH350) and it worked and is still working fine.

I had a rear end that was blowing axle seals ... turned out the vent was plugged.

 

Vent may be clogged I have not checked it yet

 

Also may just be the fluid that’s pushed up the cable, I’m gonna go unhook it and try to get it pointing downward and let it sit and see if the bullet has fluid around it tomorrow or if it’s the fluid in the cable thanks that’s probably the easiest thing I can try right now

 

When I'm resealing these, and I do it fairly often as they are a common source of a leak, I always put 2 seals in the bullet. Maybe you shouldn't have to but it seems to work well that way.

 

There is a inner cable seal and outer housing seal

Are you replacing both? or just the outer...

 

Yea I think I’m gonna also give that try too

 

BTW this should be the inner seal number... Pioneer Seal 759024 | O'Reilly Auto Parts

 

I have replaced both everything already and it still leaks, but I ordered both the oring and the inner seals again to try again, I have had 3 different brand new bullet and seals installed, and two new plastic gears

 

We’re the 3 bullets the same company? Find an old steel one and redo it. I just had one that I replaced and no issues.

 

So putting two new inner seals has fixed the leak, not sure why one wouldn’t work but it’s fixed is all that matters I appreciate the help guys
