In absolutely flat terrain, the cruise control works fine. Set it at 70MPH for example, and it holds the speed very well.
However, with even a slight increase in grade - for example a long grade over another interstate highway, etc. - the cruise sometimes drops from 5th to 3rd gear, and the tach instantaneously jumps from around 2K to around 5K. Typically, the shift is from 5th to 4th, but also quite often from 5th to 3rd gear.
I think the basic problem is that with Toyota's search for the Holy Grail in fuel economy, the 5th gear's ratio may be too high a numerical gear for the 4-cylinder's torque. At such a low RPM while crusing between 65 and 70MPH, there's insufficent torque to maintain the speed set with the cruise even with a slight increase in grade. Thus, the kick down to 4th and even 3rd gear.
I believe this problem is specific to the 4-cylinder, and not the V6 - which developes greater torque at lower RPMs.
This squares with my experience in my '05 Camry 4-cylinder 5-speed auto. I don't get all bent out of shape over it, I just take it out of cruise when climbing steeper grades on the interstates (as when going through the Appalachians near where I live).
When descending the steeper grades, I might turn off overdrive (downshift to 4th) and hit "resume" on the cruise.
On my daily commute in my '04 Camry 4 with the older 4-speed auto, I know exactly where the cruise will force a downshift going uphill, so I cancel the cruise before that happens. I can do a better job with my foot preventing downshifts from occurring. When the road levels out, I hit "resume."
It will drop out of lockout (increase about 500 rpm), then drop into 4th gear (still an overdrive gear) and go up another 500 rpm.
If it cannot maintain the speed, it will drop into 3rd (go up to 4,500 rpm) going up mountain passes.
The horsepower and torque are low below 3,000 rpm.
Don't want it to shift to 3rd? Turn the cruise off.
If the cruise did not not hold the set speed, there would be owners griping about that!
That's funny, I gotta remember that!
now i don't suppose you'd want to take your vehicle which is working absolutely per design and have it done? :surprise:
I have 14k on my car new I really hated the car and wated to trade it but now i think i will keep the car Its a big improvemnt get the TSB done Guys.
Thanks!
No, I won't get it done unless I become unsatisfied with the transmission's performance. So far, I haven't experienced any hint of 'hesitation', my fuel econ is great, and don't see a need to mess with anything yet.
I bought it for my wife, though it rides a little like her old 2000 buick century (which she likes).
Yes there is a way to determine if your Camry has the updated ECU calibration.
1) Pop the hood up and look to the lower driver side coner of the hood for a sticker titled "Toyota Motor Corporation: Authorized Modifications. The followeing modifications have been made:" followed by two numbers. The fist is 89611-##### which is ECM part number. The second is the Callibrations ID... ########. Call your service dept to determine if "3#######" or what ever code is here is the updated code.
What city are you in anyway?
I've already asked for the same thing at the other forum, but considering the 'fix' was different programming codes. There's no reason that I can think of for the hesitation to occur if what was causing it was replaced, no?
Only time will truly tell.
Except for one inconvenient minor detail: the 5-sp automatic is a carryover from the past several years. It worked fine in prior models. It's the 6-sp automatic used with V6s that's brand new.
BTW, did you get a Honda Accord? If so, good choice!
I know some of the dealerships in Toronto are doing this TSB, such as Dixie Toyota and Downtown Toyota. That said, whether you are closer or not to Michigan or Buffalo... if you are willing to, you could take that TSB with you to the states for a day trip and get it done. It should still be under warranty.
I actually would agree that some may not be used to the smaller displacement and power of an I4, and let's face it... the 07 Camry isn't a small car anymore.
I don't know if this has any effect on the cruise control issue and while there are other issues (paint, AC) I am not happy about I am no longer trying to sell the car.
I was just quoting what the Toyota letter said about the newer version.
"The poor response you described typically surfaces either when the accelerator is depressed fully to the floor or when depressed an aggressive manner. The NEWER VERSION of the Camry has transitioned from a manual throttle linkage to an electronic throttle control system. The electronic throttle control monitors the everyday driving habits of the operator and then tailors itself to make the most efficient gearshifts.
There was also a 2003 TSB that dealt with delay. When Toyota Customer Experience called me yesterday the person talking to me said that her Lexus had the problem for the first year. The Avalon had problems also according to an article posted on this forum. The delay problem has affected several models for several years.
They didn't apply a sticker to the inside of the hood and said that was for when its done at the factory. I can't believe a customer has to tell a dealer about a TSB and then have them argue with you about it.
Anyway, it seems to accelerate smoother and shift better. Its also has alot more pep. It does still have a little hesitation but only in the downshift from 4 to 3 i think.
I'll upate this after the drive home in traffic and see how it does.
I also noticed the dealer put a scratch on the bumper after i got to work, what are the chances of them admitting that they did it or am i better off forgetting about it?
Can't hurt to bring the matter to their attention. But, don't be surprised if they shine you off. If you want to attempt a paint scratch repair yourself, go on Do-It-Yourself-Network's website and access Kevin Tetz' instructional.
As an FYI, I got a new 2007 TCH and found blue pen ink on the armrest and now I am not sure if I want them to replace it, I will see if they let me do the work, if not, I will possibly not allow them do it.
What did the dealer write up for the problem and what did they write up to repair it. I bet neither one mentions delay or hesitation of the transmission.
Does it matter? If the TSB was applied correctly, and I hope it was for santhon2's sake, then who cares what they wrote. The point would be that the 'hesitation' and gear hunting are gone... except unfortunately for yours, no?
santhon2, other forums including this one (except one) have reported rave reviews about the recent TSB and what it has done for their 'hesitation' issues. So, if you feel it is still a problem, go to another dealership and ask them to confirm the current ECM code. Doesn't take long at all. good luck.
