TRD Pro 4High crawl Issue...gears?

Wha? What’s wrong with 5th and 6th?

 

Thanks !!!!!!

I've been into Drag racing and rock crawling and being a Gearhead going on over 40 yrs now

 

Yeah.. but thinner lol

 

overdrive gears seem to be weaker. I've seen 4 people blow up their 5th gear, though these werent the newer transmissions toyota is using in the 3rd gens. Maybe this isn't the case with these transmissions, but I've just developed the habit of avoiding it based off my experiences. If you're in an OD gear in 4lo then chances are you dont even need 4x4 to begin with if you're going that fast.

 

That sounds like a lot of the hills around here. I’ve had no issues. Like you, I prefer 4H for the same reasons you do.

 

I use 5th and 6th for going down the easy trails between the technical trails. It seems a lot easier than shifting into 2/4hi. Also, there are some trails in my area that allow for 0-30 mph, but not much more. I’ve never heard anything about 5th and 6th being weaker. I’m skeptical that Toyota would design a transmission with gears that were too weak to use.

 

Yeah makes sense. I usually dont go past 4th because like you said, you probably dont need to be in 4lo.

 

LOL. 4hi and crawl should never be in the same sentence.

The 3rd gen MT has the lowest final drive ratio for 1st gear of all Tacoma’s if I recall correctly.

I’d take a few more laps around the block if I were you.

 

I miss having a manual transfer case. You guys pretty much covered the rest

 

theres a mod for that

 

Thanks to all for the input , advice and suggestions. Also thanks to nd4spdbh for calling me dumb...

I think the quote above answers my nagging question about why? the most clearly. While I could go spend a couple thousand on gears, it's way more sensible to just use 4Lo more often. I guess it's simply a factor of fewer real truck application needs in the marketplace. IE- There are no US trucks available in Manual Trans except in Commercial applications. Coupled with higher fuel efficiency requirements its next to impossible to buy an off the shelf true 4x4 truck anymore. (At least not like an old Taco, CJ, or Series Land Rover) But then at least now we have ac/ satellite radio/ automatic seat adjustment/ and cameras!

Last question...What's the "long press of the trac button" going to give me? Does it just turn off the Trac in 2 or 4Hi?

Cheers guys!!

PS- nd4spdbh come wheeling in Ouray sometime mate! we'll grab a beer!

I was in same boat as you are, took my brand new 2016 TRD offroad to alpine loop and few passes there and stalled few times on hurricane pass and was totaly shocked how bad it performed high altitude. So eventually after dealing with underpower and handling of tacoma, regeared it to 5.29 and now its beast that for sure handles so much better. so to save you time one word, REGEAR and dont do 4.88 go direct 5.29 it will be worth the money and should be anyones first upgrade to tacoma 3rd gen. I dont understand why toyota does not offer 4.88 as base for TRD offroad or pro version to begin with.

my .00002 cents

 

Summary. Long press turns off traction control (system to minimize wheel spin at driven wheels) AND vehicle stability control (system to keep vehicle on intended path and counteract spinning out or plowing forward). Long press turns all this off in both 4HI and 2HI. 4LO has everything turned off by default except the traction control which is then dubbed A-TRAC and turned off and on with the A-TRAC button.

 

Yeah i was shocked when i couldn’t get moving up this hill without 4lo in one of those colorado mountain passes. The altitude was killing the already weak engine.
The 3.5 just doesn’t have the low end gusto for crawling with a m/t

 

Stability control kicks back on around 30mph /unless/ you do the long press at a dead stop

 

Just to clarify a bit, the 4lo off road traction control (aka ATRAC) behaves quite differently than the on road traction control available in 2hi/4hi. It’s a lot more aggressive at limiting wheel spin and AFAIK can be used for longer periods of time because it uses electricity instead of engine vacuum. I’m not a hard core crawler, but I am an experimenter and I have yet to find a situation where my rear locker trumped ATRAC. The same is not true of the 2h/4hi traction control.

 

It's similar to autoLSD 2wd strategy only more aggressively tuned and acts across front and rear axles independently.

Don't know what you mean about vacuum. It uses the ABS hydraulic pump and 12 solenoids to selectively apply braking to slipping wheels. It's a hydraulic system. Electricity only runs the pump and actuates the solenoids.

It will never be more capable than a locker at the peak level but it beats the tar out of an open diff. You'll learn that as you cross into hardcore.

 

We were just camping in Ridgway a couple weeks ago. I always have to go into Ouray and get a scrap cookie. Do you brew at an actual brewery there or just for yourself?

 

I'm looking forward to being in Ouray, Silverton and Lake City at the end of the month. The area is heaven.
