OMG that's rocket science! Even if it is lifetime fluid...How about a simple sight glass on the side of the case with a line on the glass where the fill level should be? I mean, I know it’s futuristic but that’s like what, 1880s technology??

Getting your car level on jackstands, crawling underneath with hot exhaust, reading temp and deciding what "a dribble" is is harder than stabbing a dipstick?While not having a dipstick sucks (for refilling purpose), the check procedure is much easier and more precise than the dipstick method, IMO
Well, no not in that case. I agree with you there. For a truck, it is easier.Getting your car level on jackstands, crawling underneath with hot exhaust, reading temp and deciding what "a dribble" is is harder than stabbing a dipstick?
Since the case would become larger, at temp, I'd think more fluid is needed at operating temp, to keep the level correct. I'd don't know for sure, just compare cold level to hot level.WOW adding this seems to bring more food to thought, so would u say level doesn't need to be precise as much? or it does?

Can you post a link or instructions? Thanks in advance.On Lexus/Toyota, the dash has the capability to display the exact ATF temperature. You need to act quick but if you read the instructions, you can do the check and be within 1-3 degrees of the required temp.
Otherwise, ya I understand what you're saying. But the option for precision is there.
The process on the 2GR is pretty straightforward, actually. It really just depends on who is doing the procedure and how much they pay attention to detail.Problem is the Toyota procedure on this is haphazard at best. To the point where a Toyota technician on this board told me that they just measure what comes out at the dealer, and Toyota themselves have issued a TSB and a bunch of new tools themselves.
Given the number of people that have done this task without issue, I do assume the the tolerance is a bit wide.
Toyota sort of pooched this one IMHO. I presume they really don't want anyone changing the fluid anyway.
Anyone know the thermal expansion coeficient for ATF? I have read everything from 0.0001% per degree C, to 0.07%?
To enter fluid temperature detection mode?Can you post a link or instructions? Thanks in advance.
Time to service our GS.
Thanks. I know about jumping the OBD II pins. I thought you meant there was an actual temperature read out.To enter temperature check mode?
I only have the instructions for the 2GR's AA81E and A760H. Basically, you jump two pins on the OBD port with a paperclip, then start the car, and quickly blip between drive and neutral with the gear lever about every 1 second.
You should find a Youtube video for the GS or else you can check this one out for the GX. The basic procedure for entering into that mode is relatively the same I think.
As for the filling procedure, I'd definitely go to TIS and get a 24 hour subscription so you can download the instructions for your specific vehicle.
Edit: if you need the entire manual for the GS and are on a Mac, I can possibly help out but you'd have to PM me. I don't want to get BITOG in trouble. Not illegal but kinda cheeky.
You're right. I was confusing Techstream with the other method. The latter just flashes when it's at an acceptable temp. But you can get the exact temp with Techstream, and the knockoff ones on Amazon are cheap. You just need Windows, and if you're on a Mac, you can use VirtualBox, and the required version of Windows is free.Thanks. I know about jumping the OBD II pins.

I just use a temp gun on the pan and set the level at the lowest point in the range.
IMO there should be a read out... There is some talk that even Toyota just replaced what they drained.
On a Windows laptop, which software are you running? Is it an expensive purchased app, or a cheap/free one?You're right. I was confusing Techstream with the other method.

When I did it, I learned from experience ahead of time that it's only a few minutes from cold start - maybe 5 or less - when the "D" shift indicator starts flashing. I had a second person in the car inform me while I was under it and I worked quickly. When I did it the second time I used Techstream.
Here's the exact cable I ordered to do it. Can confirm it works.
