2007 Tacoma cruise control problem

On a recent trip, my cruise started acting up while climbing a hill. The cruise was set at 60 MPH. As I started climbing the fairly steep hill the 4 speed automatic transmission shifted down from 4th to 3rd. After several seconds, it started switching between 2nd and 3rd rather quickly, spending about 1/2 second in each gear. The service department at my dealer said "Oh yeah, it'll do that". Email response from Toyota corporate quoted the owners manual "When driving on slippery or steep roads, do not use the cruise control". Granted, this is a fairly rare situation, but still I don't think it should do that. What are your thoughts?

There isn't a problem! When the engine gets loaded down the tranny downshifts. Followed by the rpm climbing back up where it shifts back up. My '99 Tacoma does the same thing.

"OldPhart" found these unused words:

Toybloata's cruise control seems not to have a 'soft' edge as some others do, It drops in speed, slams down, then stays in until well past regaining speed.

The best cruise control I've ever encountered was in two rental Penske trucks. Seemed to sense the terrain and NOT slam about but just allow some speed loss and then drop down and continue smoothly pulling. NEVER over rev'ved that engine the way Toybloata does in my Taco if I don't kill the 'cruise' in time.

Truly only useful for reasonably flat cruising.

It's about the only thing I truly, completely dislike in the Taco, but it's just poor engineering. I also get better milage with mine OFF!

I agree that Toyota's cruise control is "too tight". Even on level ground here in Texas it is constantly hunting back and forth of my set speed. My GM Safari van cruise control is much better. What I should have said was that there isn't a problem other than that's the way Toyota designed it.

Not that it applies here, but Toyota CC works great on a manual tranny. Seems to me like the real "issue" here is the auto tranny setup, not the CC, as CC really only interacts with the throttle.

My '92 V6 4WD extra cab pickup with manual transmission has cruise control and it works great. A short drive I do every day through the woods has many changes in elevation and lots of curves. The speed limit is 35 MPH. I put the truck in 4th gear and set the CC to 35 and just steer. The button locations are also the most convenient ones I've ever encountered. ERS

I'll second that!

I've got an '05 Tacoma V6, and I can just leave the thing in gear and drive. Plenty of torque for hills.

Hey! Got an 86 4x4 turbo pickup here under restore and was wondering where the speed control actuator is mounted on any manual trans pickup or

4runner. Might just dump in cc along with the restore. ZaXXoN

I find it quite good with my 91 RV6 4runner manual. Hitthe freeway and not havign to worry about speed cameras/cops hiding in bushes etc.

Its the first car that Ive owned with cruise in a manual though. I wondered why to start with but now Im used to it.

ZaXXoN, I believe that the actuator (mounted on fender well) is identical for manual vs auto trans. As are all the other parts. I think. However, there are LOTS of parts! At pickenpullin I've seen factory cc on '86, and earlier 22RE and turbo. YOUR wiring harness and ECU would have to support it. Tempting, huh?

(i think the auto/manual issue with cc, is about the mindset of the person operating a stick vs. the attitude of someone driving an automatic ...)

ZaXX> Hey!

Yes! I'm just wondering where the "pickup" for the CC is and how it is mounted. Or maybe it just senses pulses from the ancient 86 computer somewhere in the harness or an existing sensor. ZaXXoN
