I have tried to add Prestone auto transmission oil sealer during oil change. But it didn't help. I read about bluedevil and AT205 in some reviews. Do you guys think any one of these will help? Thanks Tom Greenleaf Ultimate Carjunky / Moderator Jan 13, 2015, 5:19 PM Post #2 of 4 (1575 views) Re: 08 sienna transmission oil leak sealer recommendation Sign In NO! 99.9% chance sealers will not fix a real problem and many cause a problem you didn't have. Don't do that. Find exactly where it's leaking as best you can. If from the front of trans where it attaches to engine could be a front pump problem causing seal to not hold and also be your noise from the other thread. Pay attention to both oil and trans fluid levels like a hawk and carry what you might need if leak is fast enough don't wait for drivability problems from low fluid level or it probably will mean a whole trans job!

If those sealers actually worked, parts stores wouldn't bother to sell them, it would just be a small room with a shelf full of bottles. Also not all of these chemicals will be compatible with all transmission fluids (although you won't see them write that on the can) and none of them are recommended or approved for use by the automaker (which you can readily find out with a little research) so the wrong one can possibly cause damage to your transmission. Also, Toyota has a specific fluid for their transmissions which MUST be used or cause early failure. When you changed your fluid did you replace it with factory approved fluid? If not you need to get every drop of what is in there out. That means all of it, not just the drain plug amount. While you are at it replace the leaky seal and then refill with factory Toyota fluid.
