if you have the skills and they have the money, by all means fix it.
i have neither, so for me, this is a no brainer.
from a purely economic perspective, $30 worth of ATF & trans-X once a year vs. a $1200 - $2500 rebuild .....
Well, for some realistic math......
ATF cost 5.50 a quart for anything worth putting in a 4EAT. 4EAT holds almost 10 quarts.....a flush ussually requires 8. So that's $44. Plus the trans-x itself is almost $10. Even at $6 that makes each flush $50 bucks. Not to mention the $30 spin on filter. So that's $80 a pop......to not even fix it just make it temporarily better (not much better in this case)
On the other hand........ if the issue is just the input shaft
o-ring......it can be replaced simply by removeiong the trans, removing TC to access input shaft, and
installing a new ring, and reinstalling. No "rebuild" needed just a few
externally accesible seals. I charge about $350 for R+R of an auto
trans. O-ring cost is about a dollar. So that's $351 dollars. 3 or 4
years of trans flushes will get to that cost pretty quick.
Besides, just telling them to live with it and flush and fill and add additives every year doesn't work in the real world of people actually wanting there car fixed. I'll be setting myself up for a bad reputation and possibly a small claims suit if I try to just "trans-x" it again. And for the record, once a year is way to often to have to be flushing your auto trans....there is a problem and it needs to be actually fixed.
Is putting the sealeant slime in a 2.5 "fixing" the headgasket? No, of course not....it's delaying the date of the actual repair, or in some cases the demise of the car. Eitehr way it's kicking the can to someone else and cashing out.......NOT the way I do business.
Now, As I said, I've already used it in this same car, and at best the Trans-x made the problem a little less severe. Never made it go away EVER. These customers are NOT car people.....and the violent slam into drive is very scary to them and they do not trust the car......If I don't fix they will sell it, and likely not buy another subaru.....so it's in my best interest, and Subaru's too, to actually fix the issue permanently.
Now espescially since we have the trans open for an unrelated Diff/pinion bearing issue, we want to address this problem and actually FIX it.
Like I said I'll just PM Ivan because he actually sees the value in "FIXING" a problem.
