4LO operating question

[Trumpet]

Bought my '07 SR5 V6 earlier this year, 4lo was inoperative, but I got it working with the heat of summer and it now reliably goes in and out of 4hi/4lo and the diff lock is butter smooth.

Just spent several hundred miles tooling around in 4lo and the one thing I question is this: From a dead stop, in 4LO, when I apply throttle there is some take up (think revs, like a slipping clutch) before the 4runner starts forward. I'm thinking this is normal. I seem to recall the '09 doing this but didn't have it very long (totaled).

In 4HI you just go with the throttle.

What's your 4lo experience??

I put mine in 4LO just to keep it working. I haven't taken it over 5 MPH though because it's already in third gear and is quite jerky. I'm not sure if this is normal or not but at least it works.

That is normal for 4lo. It is in a completely different set of gears than 4hi, so yes, it will not have the same throttle response as 4hi.

Mine does that too. Relatively certain that it's just the torque converter taking a second to spin fast enough to start locking.

That's what I figured. Love this 4runner:redface:
