Your drawing makes sense. I'll have to crawl under there in the coming week and see if I have the same situation. Visually it looked good, but I don't want to get all geared up to go and have to quit for want of another tool. Thanks.
Looks like you need a set of these: http://www.ebay.com/itm/JH-WILLIAMS-FLEX-HEAD-SOCKET-OPEN-END-WRENCH-SET-11940-/270518774674#ht_2430wt_1399I have some offsets such as you, however they would not work on my pan. The pan has a lip if you will (see my bad drawing),and wont allow the wrench to get in there.
The red part is the bolt, and black part is the pan
I am just about to do this on my wife's HL.So a swivel socket wouldn't work on those hard to access bolts?
I used a Craftsman, Deep Off-Set 10mm wrench and it worked great.Looks like you need a set of these: http://www.ebay.com/itm/JH-WILLIAMS-FLEX-HEAD-SOCKET-OPEN-END-WRENCH-SET-11940-/270518774674#ht_2430wt_1399
I have a set of Craftsman Std/Metric. They come in handy and may work here.
Mine is a 2011. It had a gasket on when I dropped the transmission pan, and the new filter I ordered for it came with a gasket.What year is your Highlander? I was told by the dealer that they no longer use gaskets, but a silicone? It appears you have a gasket, unless I missed something.
Changing your AT fluid and not changing the filter is like taking a shower and putting your dirty underwear back on...... Change it!Coming up on 50k on my 2009 Highlander (never towed anything). I plan on doing a flush of the entire system, do you think replacing the ATF filter is overkill?
Personally, with only 50k and no towing, I would just do a drain and fill and call it good for another 30k. Then, I would drain and fill every 30k after that. I think if you followed that protocol there would be very little build up or contamination remaining the the system.Coming up on 50k on my 2009 Highlander (never towed anything).
