Angry Transmission fluid capacity discrepancy with dealer

It is my understanding from the manual and many threads on here that the WRX 5-speed capacity is listed as 3.7 quarts. Also I've seen from many sources that the rear differential capacity is about less than 1 quart.

For my 30k service, I went out and bought 4 qts of Castrol Hypoy C and 1 qt. of Castrol Syntec for the rear. I get a call this morning from the service advisor that I'm about 1/2 qt short for the transmission and a little less than that for the rear diff. He told me that the capacity is more than listed for the transmission because you have to take into account the front diff . I know these guys work on Subarus everyday, but are they just mixed up about the capacities? Keep in mind they are just performing a drain and fill, not a flush or anything like that.

Thanks Unc Scotty! I was about to lay those pages on them.

It turns out the "highly trained/experienced tech that's been doing this for years" couldn't tell the difference between a pint and a quart. I don't even understand where they get the pint measurement as it's not listed in the service manual. Oh well, I'm enjoying my fresh tranny oil.

Ahem,

I just want to state that you have to add the fluid through the diff to get to the trans. Unless you want to push the crappy old diff fluid into the trans, you may want to drain the diff too. I think the tech is right. Just did mine(and am a tech) make sure you are on solid ground before you go cop an attitude with someone who is doing their job.

Please refer to Uncle Scotty's post above.
The WRX 5-MT only has one drain plug.

thats great, I didnt know it was a wrx, or that it was different. I saw the above post, I just know what i have dealt with on my own vehicle and others like it. If the vehicle holds only 4 then great. I just wanted to say that you want to make sure before confronting a mechanic. Most dont like it when you bring your own parts, and like it even less when you tell them how to install them.

That said if hes wrong then let him know

Haha, wow. The thread itself gives some examples of how misinformation leads to miscommunication.

I did the research before going with my own oils. When the dealer notified me I was short, I didn't rule out the fact that maybe I screwed up and double checked my sources. Not once did I cop an attitude with them. It basically came down to Subaru's word vs. the dealer's. Of course I put more faith in people who designed the car, and that's what I made clear to them before they got a second opinion from another tech.

Honestly, a mechanic who can't comprehend different units of measure is an insult to the other skilled mechanics and doesn't deserve whatever certification they earned. I think this thread is pretty much over.
