leaking from the top, tranny manual

[Rockinlittle325i]

so my tranny is leaking from the top, what are possible reasons?
oo ya near the shift linkage I think

[drift]

Might be a leaky detent cover seal.

[Rockinlittle325i]

what would cause that? how should I fix it? cost?

[drift]

It probably costs less than $10, and shouldn't be hard to get it done.

[Rockinlittle325i]

do I need to remove the transmission? (dumb question I know)
just so I know, how does said cover work, what is it's perpose?

Click on my 91is m42 link and there is a how to on replacing transmission seals.

Your selector rod seal is leaking!

[Rockinlittle325i]

do I need to take the transmission out? how much would that cost to replace, is it the same for your 318 and my 325?

[drift]

Get all the parts needed, and then Preferably to remove the exhaust, disconnect the driveline / flex disc, be ready to safely support the tranny with a jack stand, undo the tranny mounts to lower it down to gain some space, and carefully extract the seals ( pics above), drive the new seals in place.
