I have a 1st Gen - getting ready to buy 2nd Gen.

I have a POSI rear end in my 1st gen and I LOVE IT! i plow snow and I off road (SAND DUNES).

i love that i can push snow down into a ditch, and back out no probs (NOW THAT I HAVE POSI).

sooooo...

how do you guys like the computer aided limited slip? does it work properly in 4wd? i know it is no where near as good as a posi - sooooooooo

your thoughts? does anyone have a posi i can get for it (Scared to put on in because of warranty issues)..

also - i've read a lot of your comments/threads on snowplows

how much trouble should i have getting the dealer to work on any issue if i have a plow on my crew max? Especially IF i get them to have it installed b4 I buy the truck?

Thanks
Michael

PS - i think i'm buying monday or tuesday

I use it to annoy the crap out of me when I accelerate hard while making a turn, or gunning it from a stop.

One of their advertisements is plowing snow, go for it I do.

I know -i'm saying the same thing - Worried about the limited slip though - i wish i could change it to a posi - but they will flip out (warranty wise) and im worried how the computer (traction control) would react to it.

 

[mendonsy]

I'm not 100% sure about this, but I recall reading somewhere that the limited slip is disabled when in 4wd. You might want to check it out if you plan to plow with it. The computer controlled brakes work OK in snow, but I don't plow with mine.

In 4WD you have A-TRAC as default, which is similair to A-LSD only on all 4 wheels. You can turn it off if youl like.

Toyota doesn't want you to use A-LSD for normal driving.

I know. It's really the trac cntrol that annoys me. I just hate electronic traction controls in any form - I never like when the computer 'decides' I need it.

fire_mike,

You have no idea how fast that traction system works. Try it on a gravel road sometime, you'll learn how to appreciate those devices if you know a bit more about how they work!

Sanosuke!

try it going over rocks and boulders on steep hills, it sucks.Ill have a locker when some choices hit the market.

i agree about the locker - but i'm worried about voiding a my warranty - especially if i JUST drive it off the lot with 77 miles.. and i was told by the salesman (not parts) that they do not have an approved locker currently..

plus - im worried if i found one - would the computer not understand WTF is going on?


****thanks for everyones point of view btw****

I don't think I would worry about confusing the computer. The computer would only intervene when it detects wheel spin. If you had a locker installed there would be a decrease in wheel spin if you have equal power going to each wheel. I would find it hard for a locker to cause damage that would jeapordize the warranty, I may be wrong, but they would have to prove it was caused by the locker itself. Someone please correct me if I'm wrong.

I use my Auto LSD weekly and have had no problems with it. Works great on loose rocks and gravel, does well in the snow too. That said there should be no need to turn it on, it should be an automatic program, and Toyota should offer a real (mechanical) locker on back that can be activated by the driver.

I Hate this so called auto LSD .

Get real it's a open diff with traction control by braking the spinning wheel . It's not that a LSD from the gen 1 tundras where all that great on it's own . But having both a Real LSD and a good traction control systems would be almost as good as a full locker with out any other the negatives of a real locker .

I was once very skeptical of the traction control systems, but I've had several vehicles with them and once you learn how to use them they can work very well. No ,they are not a locker... a locker will let you have a bit more finesse amongst other things. When the ARB unit comes out (fall hopefully) I will probably buy one.

I plow and offroad with my truck, the main tip is a little extra throttle is required to get enough torque moving through the system so that when it kicks in, it can fire that torque through the diff to the other wheel. If you sit there and lightly apply the throttle, as with a real locker, the system dosn't work well, or won't work at all.

Example at a local trail. I've driven a dozen different 4x4's over it, Land Cruisers, Toyota trucks, Jeeps, a Ford F250. I know what will and won't go over this simple obstabcle on this line. At an easy pace the Tundra will unload two wheels, theyw ill spin and forward progress will cease. Too light on the throttle it will still sit there and spin... a little extra throttle, the brakes apply and bamo it transfers the torque over to the other wheel and over you go. It does work.

The A-Trac system works wonders in maintaining velocity, but its not so good if you are stuck.

I have a local hill climb trail thats on loose ground and undulating terrain. Its a big challenge to go up without lockers because it will pop the left and right tires totally off the ground. Most LSD's get stopped by that unless you apply some brakes to cheat the system to transfer power (which is exactly what A-LSD does as there are no clutch packs, its an open diff).

With the traction control off, the tundra stood no chance of climbing it and it sat there digging a hole 1/3 of the way up. The A-TRAC on however, it went right up to the top with ease, you can feel the truck transfer power corner to corner the entire time and you can feel it working. I was pretty skeptical of the idea until I put it to the test.

If you get stuck in deep mud or snow, the system seems to be way less effective than being locked up, but in all honesty if you grind to a half in deep mud or snow, your tires are a bigger factor than the differentials.

I TOTALLY AGREE _ a bunch of BS Marketing.. "auto" lsd.. BS - let's call it what it is 'an open diff w/some computer telling the brake to lock enuf to throw the torque to the other side'.. aka - BS auto lsd. - that's my prob.... NOT a true lsd (not that i want a lsd).. i wish i could get a locker as an option.

BUT - when i go to the SAND DUNES - i drive in 2wd a lot.. u need some speed to do it in 2wd.. and - wheel spin isn't always a bad thing (TOO MUCH IS).. but - im worried the auto lsd (if i dont' turn it off).. will slow it down too much - i've experienced this on other vehicles.

my wife has an 05 pathfinder.. off road edition.. i can turn off the computer braking - and it goes like a bandit.. im hoping same thing.. but i have an electronic locker in hers. soooooooooo fat chance in the tundra.

nice truck..

my question for u is - how does it work plowing? i appreciate your feedback on off roading (although it is different in sand).. plus some of the dunes - u don't want speed (speed breaks stuff).

back to plowing.. how does it work? well in 4wd?

THank you to all of you responding!!!!!

I go to the dunes all the time. I do put it in 4wd and thats it. I pull my trailer with 5 quads and one in the bed. Last weekend I pulled out a dodge and ford. Then I pulled there trailers out for them. I don't spin my tires at all. Just drive nice and slow. The trick in the sand is to let air out of your tires. (I didn't tell the dodge and ford that.. hehe)
