HMMM...well you have a non-sealed transmission if I remember right. when did you last service it? it could just be a bad seal and nothing major. if you wanna tackle it yourself heres a good diy.http://www.toyota-4runner.org/maint...-transmission-service-4th-gen-t4rs-prior.html

Well thats bad on my part. I thought sealed units came in 05. anyway since it sealed I can help you there. I serviced mine about 9,000 miles ago I used this http://www.toyota-4runner.org/maint...ission-fluid-servicing-sealed-non-sealed.html I really hope it isn't too serious in there. how much fluid do you think you have lost?

Correct and thats how you fill the transmission, you fill it so the old fluid comes and keep doing it till it's all new fluid.

Transfer case maybe?

I guess take it to a few shops and have it looked at before you do anything else. also look at it from the engine bay and see if its leaking around the engine or at least try to find it.
I am leaking fluid where the tranny bolts to the engine block. Do you think there is any chance that a couple of the bolts came loose, or would it be an expensive re-gasket job at the dealership?
It doesn't look bad in the pictures, but it's making a mess on my driveway. Its dripping, not just seaping.
Any thoughts on a fix?
If it is transmission fluid leaking from where the transmission bolts to the engine block, then possible leak points are:
1) Transmission front pump seal.
2) Seal where the torque converter is inserted into the transmission.
3) The torque converter itself.
Are you sure it is transmission fluid and not coolant? Toyota antifreeze is red/pink in color.
Correct me if I am wrong here. But according to this picture, there normally isn't any fluid in contact where the transmission bolts to the engine block? (If the vehicle is parked and the engine off)
The torque converter is always full of transmission fluid, it is located in the bellhousing that bolts to the engine block. Even if the vehicle is not running, the transmission valve body and and areas above the transmission pan in the diagram contain transmission fluid.

It is infact antifreeze (taste test never lies! lol) I need to trace it back to see where exactly it's leaking from. That's a little relief, as coolant is easier to add and see when it is low.

How many miles? Water pump is good to about 90k

Well thats a relief. its also easy to find the leak to. Well glad you dodge a bullet there.

About 67,000 miles on my 2004. You think that if the water pump seal is leaking it would track all the way back to that point?
And yes SkylineGTRracer, that is a relief that it is coolant rather than tranny fluid leaking. I would hate to see that repair bill at the dealership. I still hope it is nothing major!! *fingers crossed*
Anythings possible, but I think it is unlikely that a leaking water pump would track coolant all the way back to bottom of the transmission bell housing. Check your heater hoses and their connections at the rear of the engine and at the firewall.

Are there coolant lines under the intake heating the throttle body? Any leak on top of the engine will tend to flow down to that point. The engine itself will be warm enough to evaporate the coolant, but that area is cooler and the coolant will collect there. A hose is most likely, but some are pretty hard to get to on modern engines.

I am going to have to remove my air intake to take a good look on that side of the engine block. Hopefully it's something obvious and easily fixable. The closest Toyota dealership from where I live is over 670 miles away! :wow:
