Transmission leak

Hi all,
I am new here and in need of assistance. I have an '89 Bronco II that is leaking fluid from the transmission dipstick tube. The 2 piece tube came apart, so I don't know if it is coming out of the actual tube, or leaking from the rubber seal that holds the tube in the trans. If anyone has ran into this problem please chime in! I was going to pull the whole tube assembly out and replace the gasket, and weld the 2 tube pieces together. But my fat hands don't like it up there. Thoughts?

Hi all, I think you have to go out full tube of the gauge, it is not easy but it is possible. When you have it in hand you will be able to judge what is best to do, whether you repair it, or you mount another in good condition.

Thanks for the reply. I am confused on what you mean by "go out full tube of the gauge"?

Disassemble to the vehicle. Unbolt the bracket on the gearbox near the cylinder head and check the o-ring that fits into the crankcase of the gearbox.

I don't know for certain, as I have no B2, but my guess is there is a failed o-ring in the dipstick tube joint

Got the dipstick tube out. But, I can't feel the o ring from the outside. Do I have to drop the pan to get to it?

No, normally not, the o-ring should be on the tube, but maybe it's gone in the crank case, in which case it's better to remove the crankcase to see if it's in it.

Good luck.

Does anyone know where to buy a 1 piece dipstick tube for an '89 Bronco II?

Hi All,
Amazon.com, Ebay.com or a crashed car park.

Is there not a "gasket" that goes in the dipstick hole? Or is just a rubber o ring that goes on the dipstick into a metal hole? Thanks

Hi All,
The gauge tube is in two parts, one part is on the gear box, the second part is in the first one, there must be an o-ring every time one enters the other.

You should find in the trade this kind of set, there are all sizes:
