Expansion (Freeze) Plug Replacement

Howdy all...once again I need some help from your banks of information lodged into your 2G Ram craniums.

99 Ram1500 4X4 66,800 original miles
5.9L
Automatic.

I recently replaced an easy to get to expansion plug on the front left side of the block. Low and behold, as expected another one springs a new, but slow leak. This one seems to be from the aft end of the block, where the transmission mounts to the block. I can see one that isn't leaking, but I cannot determine if there is an upper and a lower expansion plug on the left side, rear end of the block. I can only assume there is. I can trace the leak up to that vicinity, however cannot determine the origin. I have to assume there is a plug there.

My question is, is this a plug I can get to w/o having to pull the tranny from the block, or am I best suited to take it in and pay the exhorbitant labor to get it done?

Any of you grease monkey, wrench turning knowledgable guys got any clue(s) for me?

I appreciate the help guys. I have to go hunting in 2 months, a 5 hour drive one way and I don't want to run into any problems...especially on a 30 degree incline climbing a mountain.

JB

IIRC there is an "allen type DRAIN PLUG" for water jacket on each SIDE of block, at the lower/rear of jackets.

If I remember right, there is a large freeze plug between the allen type Drain Plugs that key99 mentioned. The freeze plug is straight up from the crank at the top of the block. Sorry, but you have to pull the engine or transmission to replace it.

... Woodstock. I think that would be the CAMSHAFT plug, with LIFTER GALLERY plugs(allen type) on each side of it.

... There are 2 freeze plugs for water jackets ON BACK OF BLOCK; 1 on driver side(at 9:30), and 1 on pass side(at 1:30), when looking at crankshaft from rear..
.. Is intake mani to "head intake surface"(heads have rear coolant ports) leaking, and draining down btw block and trans?
... Check mani bolts for wet/corrosion.

Yep, you're right key99. I could only picture in my mind that plug (camshaft) in the top position on the back of the block. I usually have a small block laying around to go look at .

Get the brass freeze plugs not the steel. You'll only have the same problem years down the road. My .02 worth.

I will check the manifold for any leaks. It would be easy to find since the engine is all but showroom new.
