cruise control

I have a 2011 excab with a 2.7 liter motor and 4 speed transmission.
when I use the cruise it accelerates wildly at the slightest incline. Is this normal?

Mine maintains the set speed just fine. It accelerates on inclines but just enough to maintain the set speed.

It will first unlock the torque convertor, then downshift to 3rd if it needs more power to maintain speed up an incline. That causes the RPM's to go up, but the speed should remain fairly constant. That's how mine works anyway.

I will usually kick off the cruise control when I sense it is about to downshift and let it lose a couple mph rather downshift to help mileage.

Yes, it is downshifting from 4th to 3rd.

will this harm the engine? It maintains speed just fine but the rpm surge scares ya.

same here. That's why I just turn off the cruise control when going up a hill then turn it back on when on top of the hill or back to flat grounds.

Mine's the same. The issue is that the CC doesn't 'try' hard enough early enough when starting up a hill. Many times the truck can climb in high, but the cruise waits so long while loosing speed that it then has to down shift. Then it over speeds, lets way off the throttle, upshifts and starts all over again with the cycle. I will usually start pressing the accelerator as the hill starts and let up slowly so the speed will stabilize then it's cool and stays in high with the converter locked. If I suspect the hill to be too much for that I'll manually put it in 3 then the converter stays locked and the CC can manage better. The other option I've found is to give a few taps on the accelerate button as it starts up a hill to force it early and once I feel the load, speed, and throttle is stabilized I tap it back down.

The easy fix is to turn it off as previously stated, but I'm a CC junkie so I learn how to help it work instead so it can proceed with the hill and the rest of the drive. I'd drive by button full time if I could get everyone else on the road to drive a steady damn speed.

My "cruise" is attached to my right hip. Love my simple little Taco but Cruise and pause wipers would be great.

I paid quite a bit extra to have it added in when I bought my little 5 speed base Taco. I had them put it in when I bought it at the dealership because I'm not the best researcher. Definitely look into adding it, if you're smart, you'll spend a lot less money on it than I did.

You have my attention. Literally, all this little rig needs is cruise and delay wipers. It is perfect for what I use it for. Coming out of two competitors vehicles immediately before it, I have a great appreciation for its basic goodness.

Pray tell what the dealer charged you...???

I saw somewhere here some one had put cruise control in their truck for under $200 and that it's fairly simple. I can't remember the exact amount the dealership charged me but it was under $1,000 but over $500.

The power of the I4 is frightening for sure.

My 6 cyl. is fine but a Camery I had would come close to matting it climbing hills when it got to speed it leveled out never went more then a couple MPH over the set but it was hell bent to climb the hills maybe being a 4 they put more throttle to it. Both were stick shift.

Cruise is easy to add and probably just over $100 if you shop online. I bought the stuff from the dealer at about $130 (not including the new cover) because I was in a hurry. You need the switch, a wire, two screws, and a new plastic cover for the right side of the steering wheel with a hole in it for the switch. First--Take the two side covers off. They were hard to figure out at first, this'll help. The covers are kinda D shaped and where you wanna pop it is right in the center of the flat part which is toward the rear of the truck. Use a thin tipped screwdriver and push it in the center of the flat portion of the cover and pry off, the cover will now pull out and off. Once you see the little locking tab you'll get why you start there. Do the one on the right first so you can practice on the one you're tossing out. There's a torx T30 under each of those covers, remove them and that lets the horn pad/airbag unit pull right off. Remove the existing wire that's in there and replace it with the new one. Install the switch with the two screws you bought (phillips head I think) and plug in the wire. Reinstall the horn pad and side covers. Turn the key on and press the cruise power button and you should see the green light on the dash light up.
I didn't get the new cover and just plan to drill mine, but since I can't see it from the driver's seat I always forget, I'll go scope it out now that it's on my mind. I think I spent all of 5 minutes working on it, but I'm a seasoned mechanic. I'd guess 10-15 minutes for an average weekend wrencher and maybe 20 for a total novice. Beats the heck out of $500+ to have a dealer do it!!
