BTW, I have been coasting Tundra in automatic neutral for years, yet I just learned Jeep Cherokee doesnt like neutral coast (wheels lock if u tow), but is it ok to coast Tundra?
Also is there a way to moderate cruise control surge?
Well, you can do it...Though i recommend against it...
I have had around 20 vehicles over the years, and only 2 automatics...(14 were Toyotas, and the Tundie is my 1st Toyota automatic)...I used to coast in neutral all the time with all the manual trannies...So, I tried carrying it over to the Tundie...Until a few weeks ago, when I just topped a hill, going down, also in the middle of a nice curve, at 55-60MPH...I guess I shifted a little to fast, and it slipped past N into Reverse...
Locked up the rear wheels, the ass end kicked to the right real hard, and I left several feet of skidmarks on the road (and maybe even a little in my shorts..
)...Luckily it only ended up stalling the motor before any (obvious) permanent damage to anything else. At first, I thought maybe I had blown the engine...It was not fun coasting down the hill with no power steering, (several more curves), in neutral, and I was also a little distracted by kind of freaking out wondering what kind of damage I had done...Other than I think this is how I ended up breaking one of the rear leafs in my pass. side leaf pack.
It wasnt fun, as there were a couple cars right behind me, and also a couple vehicles coming up the hill right in the opposite direction right in front of me...Could have been a very serious accident.
Needless to say, I no longer try to save a small bit of gas by coasting in neutral with an automatic tranny...
As to cruise control, I dont bother using mine...I've always had a pretty steady foot, and been able to maintain a constant speed up or down hills by light throttle control...Again, much easier to do with a manual tranny, and I guess a habit from driving them so long...
The auto in the Tundie seems to have a hard enough time knowing when to up or down shift on hills, that if I do use the cruise, its even worse...And consiquently even worse on fuel efficiency...The only and few times I use cruise is on long, flat stretches of expressway (freeway, for all you left-coasters)...
