I tell it its a scion frs and download the enhanced add-on, it seems to works and finds a shitload of modules but then won't show them.

There is no such thing a toyota 86 listed in enhanced add on.

I got it to work by telling it was a 2017 Toyota 86 in the app, it displayed data is this correct way of doing it since its a 2014?

I noticed the transmission temp reaches past check temp quickly.

You have enough time to do the leveling process but you got to go fast. It helps if you are already under the car setup ready to go and have a 2nd person turn car on and watch temps yelling when its 108 and can make sure you’re done before 117F, first time i did it i was too slow, mostly because of how overfilled i had it before leveling it, it took a while to drain. Had to stop, cool down, and level again.

Does anyone know with a bluedriver and app where trans temp is located under live data.

Here is the PID for it. works with scangauge, not sure about anything else.

@86TOYO2k17. You are a lifesaver. Hopefully this PID works on the OFT

Thank you OP for the instructions but everyone following the DIY please be aware that the drain plug torque value may be incorrect. Even the referenced service manual had inconsistent Nm to ft-lbs conversions.

Per Nm values in the service manual (SM):

Refill plug: 39Nm / 28.76 ft-lbs
Overflow plug: 20Nm / 14.75 ft-lbs (incorrectly converted to 27.3 ft-lbs in SM)
Drain plug: 20Nm / 14.75 ft-lbs (incorrectly converted to 7.4 ft-lbs in SM)

I unfortunately used 27 ft-lbs for my drain plug and stripped it....lesson learned. Hope no one else makes the same mistake!

Ouch. I followed the torque specs I had posted and didn't have any issues, but to be fair I followed what was in the guide inside techstream. You are quite correct that the Toyota official instructions incorrectly convert from metric to standard. Quite an oversight.

I'll update my OP.

Does anyone else's trans make a bad crunchy noise when putting it in park only when in fluid level check mode?

Great write up, however, when I order the gaskets this is what I got. None of these were correct. The drain and overflow plugs are actually crush washers, both the same size. The fill plug is an o-ring, but none of these were correct.

Howdy,


Sorry about that. I'm not sure if these part numbers changed or what. I just looked it up and the drain and overflow plugs both use the same crush washer which is part number 17008AA000.


I'm still looking to find the o-ring for the fill plug. The good news is you can re-use the ones that are on there without too much trouble, usually.

[86TOYO2k17]

Reused at least a half dozen times with no issues.

[Daily86]

I did reuse the original parts. No worries. Just wanted to get the information out.

thank you very much for your post, it makes things a lot easier.

LOL
I went to the Subaru dealer yesterday for crush washers and fluid. They didn't know what fluid or know what crush washers I needed. They said they have never worked on a auto BRZ....Go to Toyota to get the stuff.

So my local dealer still doesn't have a procedure for the auto fluid change.....

So I went to Toyota and they had the fluid, but no idea on the crush washers. Supplied me with a tray of 20 or so different ones and asked me to pick out the ones I wanted.
Then he asked why come to them, it's a Subaru.....
