The SR5 4x4 has limited slip in 4WD and both axles!

I tried to research the Auto LSD function in the SR and SR5 model trucks before buying but the information was sketchy. Some people on the forum said it works in 4 Low and some said it doesn't. The owner's manual says it works in 2WD only.

I tested my 2016 SR5 4x4 V6 Auto and the limited slip feature works all the time in 2WD and 4WD and on both axles! You don't even need to turn it on, it is always working but it is more aggressive when turned on (only able to turn on in 2WD mode). Video I made of the testing is below:

Thanks for doing this test!

Thanks, but I couldn't find where it says that TRAC works on the front axle too in 4 lo. One problem I had when researching someone asks a question about these systems a bunch of people respond and some of them say things that are contradictory.

 

"TRAC (Traction Control) is solely responsible for maintaining traction. Making sure that none of the wheels are needlessly spinning because they have lost traction. It accomplishes this by applying brakes to individual wheels as it sees fit. TRAC will kick in anytime it detects wheels rotating at significantly different speeds – such as starting in icy conditions, driving through mud or snow and lifting a tire while offroading."

First line in the 4 lo table has TRAC on and VSC off as the default in 4 lo.

Some nice folks really put a whole lot of work on making that chart right. They did a great job. Not trying to be an ass, it just might save you some work.

 

I used to have a driveway that was a steep hill. backing up i had to put it in 4wd. You could feel the LSD on the front and rear axles. So only in certain situations would you notice this. but its true

 

Pretty cool, thanks for doing this test as mentioned above.

I was a lil worried one of the jacks would punch something under the truck or your rocker panel but looks like you got away unscathed.

 

Very nice work!

There's another SR trac example towards the end of this vid, aprox. 0:28sec when the front wheel lifts:

 

Not a video, but you can see my investigation of the OR (bench test) here

The work in that thread really started us on the way to make the full tables
[Edit for incompetence]

 

A different way of looking at those tables (from my 2lo visor reference card, see 2lo thread in my signature)
