i have a 2004 6 with a manual transmission, i removed a drain plug that i cannot find infor on. it is to the middle of the middle of the underside
and was a large torque bolt facing sideways,a redish fluid came out. above it in the engine compartment there is a large flat allen head fill bolt. please advise what fluid goes in and how much. i checked the haynes for fluid list and plug locations and cannot locate it. help is needed!!!!!!!!!!!!!!!

 

The trans fluid used is dependent on where you live actually. It says your in San Antonio so it would benefit from using a thicker oil than what it came with.

GL4 or GL5 (cold)
75-90 (moderate)
80-90 (above 50 degrees)

The hotter the environment the thicker the oil you want to use. If you use a thicker oil and it gets below 50 degrees then it will shift a little stiff until warmed up.

 

problem is, i am not sure this is transmission drain plug, most posts/internet
sites, claim near rad. with fill on top and drain on bottom, this is located left and below of brake master cylinder

 

If it has a spring and check ball in the hole it is for a shift rod detent. If it has a smaller diameter protrusion about 1 inch long then it holds reverse idler gear. If it is just flat with maybe a magnet on it it is likely a fill plug.

 

it is a large diameter with a torque bit head and standard theads,it is the fluid and the location that i am concerned about,the fill bolt in the engine bay above it is an allen head, if you look directly at the master cylinder, it is left and directly down about 12-14"

 

Why not just put the bolt back in, drain and refill the trans.

 

See this diagram.

 

not sure what and how much fluid goes into this fill plug/drain .

 

Drain and refill is 3 quarts.

 

Pour the new oil into the fill hole until It flows out.
