I actually disagree that LL80 is the only way. Redline works for me and satisfies requirements of LT and LX.

 

Not all countries got Redline sadly, otherwise no objections to that.

 

Thank you for the correction! In my ignorance, I forgot about that.

 

No worries. As a matter of fact sometimes I import fluids and oils from USA, some to try out, some I use regularly on my own vehicles. Many chemical products from US are indeed superior to what worldwide pool of big brands/generics have to offer. I loved Redline WaterWetter on my old Northstar V8 and it freaking worked, unbelievable. Nothing like that locally available still. I can also name seafoam products obviously, rislone, penzoil, techron as brands I import and respect.

 

Thanks, I know what fluids the car takes and I have access to techstream, I think that pdf is for older models.

 

Printed it out of 2013 model fsm just to be up to date.

 

Thanks Boykie! I'm going to do a dry run with that procedure tomorrow.

 

Not the case. It's a felt filter media, not a metal screen.

 

Just logged into TIS and confirmed there is no specified temperature range for the LS application. There most definitely is a published temperature range for the AA80E in the IS F and GS F and believe it or not they are significantly different. FWIW, the fluid volume in both the F cars is significantly greater than the LS, and I can only assume this is a result of the large transmission coolers these models have. The procedure for adjusting the fluid level is essentially the same for all three models with the exception being the LS with air suspension requires an additional contact to be connected to disable the air suspension while the engine is running with the wheels off the ground.

FWIW, the IS F temperature range is Data List: [A/T Oil Temperature 1] 35 to 42°C (95 to 108°F)
RC F and GS F are Automatic Transmission Fluid Level Adjustment Temperature - 45 to 56°C (113 to 133°F)

Given this there is no way to know what the temperature for the LS460 should be without connecting Techstream and reading the data when the P starts flashing and reading the data when the P goes solid.

I have to wait at least 8 hours to get my IS F cool enough to check/adjust the level. GS F is a little better, but not much. Alternatively, if you do this on a really cold day (4 - 5C), you'll need to hold the brake and idle up the engine in D to about 2000 rpm to get the fluid warm, or let it idle for 35 - 45 minutes. AMHIK.

 

I thought the main difference between the AA80E and the AA80F would be the awd portion, the gearing is almost identical but the ecu is different I suppose.

The ISF is on the left,

 

Hold on, I think I can find this




I would say unless the trans has altered part numbers or design in 13+ just use the 07 spec since it's the same unit. The F cars have different setups that I am willing to bet are accommodating the coolers that likely have thermostats and track use to ensure the fluid levels do not get too high and start dragging on the drum bodies and frothing the fluids, that or a simple difference in pan setups. If you have even a basic modern scan tool you can do the flashing light test mode and then see what range the tool says it is, this shouldn't be that hard to figure out if someone has hands on a 13+

 

This is what's in the book. There is something different about the 2013 model, because the New Car Features does not repeat from year to year unless there is a change. There is a whole new section on the AA80E and AA80F for 2013.

IS F ratios:


2008 IS F



2007 LS460



2013 LS460 AA80E



LS460 AA80F

Looks to me like the internals are mechanically identical, but there may be many other differences. The IS F has an elaborate breathing system not found on the early model LS460s to prevent ATF from sloshing out under high G loads. Pretty sure RC F and GS F are similar if not identical.

 

We need someone with a 13 pan to compare it to an 07 pan, they may be running even less fluid in it to minimize drag even further. Strange that they just don't come out and say as much but given I don't have access to a 13+ right now I can't say for sure if there is a difference in mechanicals or in fluid fill temp vs the 07-12 cars, they may very well just have it filled when hotter/closer to sustained operating temp to boost mpg more. The AWD cars are obviously different than all the others including the F-cars

 

I did the temperature test with the jumper today, thanks Boykie... didn't use the third pin to disable the suspension because I was on the floor and not raised.

It didn't take longer that 10 minutes idling before the indicator light(D) came on to let you know it was at temp. I connected techstream and the trans oil temp was 97.2 F, it only took a few minutes before it was at 100 F so you'd have to move fast if you had to add more fluid before it got to max temp.
It looks like it's similar to the chart of the 2008 460 AA80E that Striker posted.

 

Good job and good benchmark! What was outside temp? Really useful.
But otherwise - it's the...way she goes!
