Transmission extension housing seal - were the tail shaft goes in
I would also service the trans as that oil is burnt it should be red.

I just serviced the damn fluid like 4 months ago. Granted the fluid has never ever been changed before that :(

Maybe another top up?

When you drop the pan and oil there is still about 2 liters in the torque converter .
If it was really dark brown or black this will mix with the new oil changing the color.
Your call but I would replace the extension housing seal drop the oil again and also put some LUKAS stop slips in it, it helps rejuvenate the seals and coates the bands and clutch packs thus helping to extend the life of the trans.

Before you go further just check the valve cover gasket or the head gasket near the firewall isn't leaking. They sometimes leak their in that hidden spot between the head and the firewall and drip down onto the transmission.

You can replace the extension housing seal, but it will leak again within 2000k's, take the extension housing off and replace the bush and the seal at the same time, the bush flogs out and then the seal goes, so just replacing the seal is just a band aid fix, the tailshaft flaps around in the extension housing flogging the seal out again.

Just make sure you align the hole so it lubricates, there is a special tool for fitting these, you might have to get a transmission shop to fit the bush, just take them the housing and the bush.

I bought the car second hand, and when I drop the pan to change the oil at 300k, the filter still said "made in USA" for ford. I guess it has never ever been change.

TQ 95 is bright red, I guess it's really dirty, that's why it has turned yellowish back?

Is it this part to replace the seal?

[prktkljokr]

Early type seal, but will do the job fine

Yes; engine oil can leak from a leaking valve cover gasket near the firewall down onto the trans extension housing. In you case it is probably ATF from the transmission but nonetheless, just in case it's not, it's worth first checking for oil leaks between the back of the valve cover and head near the firewall before starting work on the transmission or extension housing seal. it's just a matter of wiping your hand around there or checking with an inspection mirror to see there are engine oil leaks there. Or if you aren't concerned about the associated health risks, do a taste test of the leaking fluid to see if it tastes like ATF or engine oil.

There seems to be a huge price difference for the power steering pump between wreckers ($60) and autoshops ($180)....

There autoshops says they 'renew' it? Are they full of ****?
