'85 720 5 speed transmission white plastic breather vent


Recommended Posts

Posted

I broke the white plastic breather vent on while cleaning my 5 speed trans prior to installing t back into my 85 720 truck. I found a new NOS vent on ebay for a 240Z would they possibly be interchangeable. Thanks to all that comment on Ratsun.

Are there measurements available for the 240Z one? It just has to fit in the hole where your broken one was, so just needs the to be the same size.

That I’m aware it has to fit in the original bore. I was curious if anyone had previous experience before I purchase one.  Thanks

The 240z 4 speed through August '71 will perfectly match the late 720 5 speed. However the '72 and up F4W71B 4 speed is different. It might still work though it's different shape and part number. See for yourself.

Previous experience breaking one.

Yes...

I tried looking back for what I bought and couldn't find it.... 

I am pretty sure I bought what visually looked the same...

Did it look like this?

That's the one for the '71B 5 speed and probably others but the 71B 4 speed one is flatter.

Yes it looks like that one and I ordered that specific one yesterday it was about $14.00 delivered to my door. So hopefully it will fit, thanks for your suggestion.  I now have to get the piece that was left in the bore removed. hopefully what's left of it will come out without too much resistance

The one you pictured is much flatter and appears to be considerably larger in diameter. I doubt it would fit in my trans. The one that chrashtd420 suggested looks identical in shape just hoping it's the same dimensionally.
