Transmission fears sadly confirmed...

You could always experiment with 2WD and lower tire pressure, then if you feel you have inadequate traction, switch over to 4WD. I personally wouldn't run it in 4 high under those conditions, but that's just me.

 

I've resorted to 4hi, no trailer...spreads 15-25 mph. Trailer, 4lo speeds 8-10 mph. Should work out fine.

Hope this is helpful. Literally NO ONE I know and wheel with dies 4lo in the beach.....but with the trailer....it all made sense

 

Happy wheeling! May your transmission last a million miles.

 

All of the Toyota's I've owned lock out the OD gears in 4LO if you're in D. You can select 1st, 2nd, 3rd, 4th and stay in that selection range. Max speed maybe 35-40mph without OD gears involved.

I also read about the 2019+ Toyota trucks locking the trans more often in order to keep the pan temps down to "expected operating temperature range". Manipulating software is slick, but to me basic over-engineered cooling capacity is better.

 

Is this the time we introduce a Power Steering cooler? Especially for sand…
