I just bought my ES used with 50,000 miles on it, and since I don't know what, if any maintenance was done on it, I've decided to go ahead and change my automatic transmission fluid. Let's not get into this debate again on how or when (if ever) to change it, I just want some advice from those who have done it on a few things, namely where you buy your washers and seals.

1) Can someone give me a link or tell me what size washer i need for the ATF overfill drain plug? (the one that covers the straw). Come to think of it, I'm having a hard time finding the plug itself. Is it the same type of washer as the oil drain plug?

2) I have no luck finding a replacement straw, but what i really need is the o-ring that comes with the straw. Will my local lowe's or Home depot have it?

3) What fluids are you running in your transmission? I wanted to use amsoil but they are incredibly hard to find in store. I've thought about using Valvoline maxlife since its compatible with WS and people at a toyota tacoma forum i visited recommend it highly. I've also heard toyota's OEM fluid is trash and might not even be full synthetic, but I've never had experience with WS to know.

Let me know what you think. Any advice is appreciated.

As far as the atf, I would use Amsoil. You can order it from the Amsoil web site, or see if there is a dealer near you. Good luck.

You can get the following items from any Toyota part department:
1/ Drain plug 90341-12034 ($3.38)
2/ Drain plug tube 35125-07020 ($2.04)
3/ Trans pan gasket 90430-12008 ($1.32)
I used OEM Toyota WS fluid for ATF changes.

Hey Thanks for the reply! Is this what you bought for your car? It says on the ebay websites that its not compatible with both the 2013 ES350 or the Avalon.

I'm just going to order the Amsoil off their website. Its almost impossible to find anywhere else.
