TRD sport no TRC or A Trac type thing

So on my 06 trd sport, there doesn't seem to be any button where you would normally hav stuff like trc and all, it's empty
So does it actually hav no sort of thing like that or it does but it's not like you could turn it off?

 

Stability/Traction Control didn't become standard until 09, it was only available with select packages prior to that. It's pretty uncommon to see pre-09 trucks with it, if you don't have the Trac off button then your truck doesn't have Traction/Stability Control.

 

So it has no type of like auto lsd, diff lock etc

 

TRD sport had an LSD, look at the rear end and it'll say use LSD oil only if you have one.

 

No Traction/Stability Control.
Your truck being a Pre-09 TRD Sport should have a true limited slip rear axle, after 09 all Gen 2 trucks had a simulated limited slip using the ABS system to apply brakes to the slipping wheel.
The locking rear diff is exclusive to TRD OffRoad models.

 

I believe and correct me if I’m wrong
Diff Lock is for “TRD Off Road” models
Auto LSD (breaks LSD) is for a certain model year after 2009(?).

Mechanical LSD is available for TRD Sport for a certain model range, you have to look at the rear end if it has this sticker.
Denoting “LSD Oil”


If you pop the blanks, it has the plugs for it but it doesn’t terminate anywhere on the other end.

 

I'm a little confused, is there no type of traction or lsd type thing at all or it has some type of mechanical lsd

 

Yours would have a mechanical LSD but no traction control.

 

Ah k, would it come up in my Guage cluster when I start it up, cuz when I put it in "on" position I don't ever see any LSD or TRC type thing, the closest thing ic is the ABS light



Too what I've noticed as experienced icy Canadian winters, this truck in 2wd skids like crazy all around, it's almost like driving a drift car, no traction what's so ever but with 4wd on it handles like there is no ice or snow at all, as if it is just pavement there. So does this mechanical lsd only work wt 4x4 on?

 

You may or may not have some sort of limited slip rear axle. Doesn't matter anyway because they are quite "limited" as to how helpful they are. They have more negatives than positives, especially on ice or snow.

Newer vehicles have some sort of traction control which uses Anti-Lock brake technology to sense when one wheel is spinning. It applies brake pressure to that one wheel forcing power to the other wheel on that axle. It works great to get you moving when stopped in a place where one wheel is on ice and the other is on dry pavement or similar situations. Works pretty well in mild off-road driving.

But off road in harsh conditions, they hurt more than help, that is why it is best turned off when driving off road. Every time one wheel starts spinning brake pressure is applied. It's usually better to let it spin and keep moving. If not turned off it's like driving while dragging an anchor behind you.

I'm pretty sure none of that is available on your 06, it isn't on my 07. I do have a locking rear diff. But it can only be locked when in 4lo. If you had a locking diff, you would have the switch on your dash in my pic.

For driving in ice/snow just continue using it in 4X4, that's the best option anyway. Limited Slip or locking diff's are actually a disadvantage on ice/snow other than to get you moving from a stop. The way you describe drifting in 4X2 it almost sounds like you do have a limited slip axle. If only one wheel spins in ice/snow your vehicle will still continue in the direction you're traveling. But with a locked diff or limited slip you'll get both wheels spinning. That is when gravity takes over and the rear of the vehicle wants to go downhill. Since most roads are crowned with the center higher to allow for water to drain that means the rear end of the vehicle heads for the ditch.

Traction control, if you had it, would be a huge help on snow and ice in 2wd. My newer 4X4 2014 F150 and 2020 Explorer have traction control and it makes a huge difference in 4X2. But since you have 4X4 it is still the best option even if you had the newer technology. Just watch the road and if you're in patchy road conditions switch back to 4X2 once on pavement then back to 4X4 when needed.

 

Mechanical LSD does not have any electrical input to the dash its all in the rear diff. Post #6 shows you an LSD diff tag.
Traction Control switch is shown in post #2 pic and is normally On - dash light shows when Off - if your Tacoma has it.
Post #10 shows the TRD Offroad (Not Sports) electrical switch that when in 4Lo only you can activate a motor on the rear diff that locks the 2 axles together and at the same time triggers Trac Control Off (no ABS help) and no engine management (throttle control) all of which light up on the dash. Located on the rear diff - drivers side top front of housing see pic below.

Owners manual/book explains and the drivers visor should have info on 4wd options.
Other switches can be the DAC (downhill assist control) and RSCA (side airbags off) so on extreme side tilts they don't fire when offroad but will be in full rollovers still.

 

Yeh makes sense, u hav a trd offroad I'd assume?

 

I can't seem to find my owners manual? Is there a way I could find it online?

Yes, had a look at the diff it does

It's kinda hard to see but you can see the sticker

 

oh boy... if thats the rust on the backside of the axle.... i cant imagine what the rest of the underside of the truck looks like.

 

Been untouched for more than 16 years, fully stock man the rust is insane, rip the whoever my mechanical will be for an AAL

 

Btw is a mechanical lsd better than auto, this is what I've heard in some places?

 

They both have advantages and disadvantages but it seems most people prefer a mechanical LSD over a brake based simulated LSD.

 

Is it better for offroad tho?
