Hi the transmission cooler hard lines where they connect on the AT are dripping pretty good now on my '96 Legacy Brighton 2.2L. I got the new parts from SubaruPartsForYou but was wondering ... how much fluid is going to leak out when I unhook these lines? I wasn't sure if the torque converter or something might drain out? Especially out the shorter line that has the ball and spring behind it? Any other tips for a simpler replacement? Thanks.

 

not a ton,

none from the trans,

only what is in the lines and radiator.

 

do one line at a time,

not both.

opening both will allow air in one and fluid out the other.

 

if you are really concerned,

open both at once and let the system drip / drain into a catch basin.

then come back later and do the work.

this way you know EXACTLY how much youy lose.
