5th & 6th Generation (2002-2006 & 2007-2011)Toyota Camry Discussion for years: 2002-2006 & 2007-2011
Topics of discussion range from fuel economy, safety, modifications, performance all involving America's favorite family car, the Toyota Camry.
I'm looking for some educated guesses on a problem I'm having with my '02 I4 Camry LE automatic w/145k miles.
When it shifts from 2 to D in "normal" driving conditions, there is a noticable hesitation as it switches gears. It only does this between 2k-3k RPMs (about 25-30 mph). If I accelerate quicker, like getting on the freeway, it has no problems. If I accelerate extremely slowly, no problems, either. And, if I manually shift through the gears, again-no problems.
My initial thought was that the transmission is shot since it's a higher mileage car, but since the problem is only apparent in that specific RPM/speed combination, I thought (maybe hoping, actually) it might be something else (computer maybe?).
Let me get this straight, your shifting from P> 2 > D? You might have some problems on your hands if thats the case.

Sorry for the confusion. When I put it in D, and accelerate from a dead stop in normal driving conditions, it does its automatic shifts from L, to 2nd, and hesitates when it is automatically shifting from 2 to D. When I put it in D and floor it from a dead stop, there is no hesitation, and when do the same accelerating as slowly as possible, again- no hesitation. I only manually shifted thru the gears for troubleshooting, which again did not show the problem.
ok i think i understand what you are talking about. let me reiterate:
when you are driving, your car shifts normally from 1st gear to 2nd gear(not L to 2). when going from 2nd gear to 3rd gear(not 2 to D), you feel a hesitation, correct?
This is pretty normal with I4's. It feels weak going from 30-60, right?
Yep. You are dead on. Sorry--I was calling the 4 automatic gears L,2,D, and OD. I guess proper terminology is 1st,2nd,3rd,4th.
This only started happening about a week ago, and very noticable. It's really more than a slight hesitation, more like about a half second, where the car noticably slows while it is finding 3rd gear. When it finds it, it jerks the cars slightly as it engages, and then it is fine after that.
in that case, i would get your transmission diagnosed. Have you been changing out your transmission fluid/checking the fluid level? would you be able to take a video of the hesitation?
ATF level is fine. Last change out was around 120k miles. I'll see if I can video the problem. May just end up taking it to the dealer to check the tranny.
when i had my 05, the trans started acting up, then it through a code. I don't remember what the code was, but i remember it was for a speed sensor in the trans. They replaced it and it shifted better then it did when it was new

Took it in to the dealer. They spent 3 hours "diagnosing" it, and came to the conclusion that it was "some sort of transmission problem". They suggested a drain and fill transmission service. 2 hours later, they said the fluid was dirty but didn't see any metal. They tested it again and said that "when shifting into 3rd sticking in valve body." The suggested repair was a reman transmission costing $3988. The tech and service advisor seemed like they just wanted to get me out of there as fast as possible.
They didn't mention reading any codes from the on board computers, and the MIL wasn't on. This specific dealership was pretty worthless. Problem seems less severe now, but still slightly noticable.

The MIL wasn't on, or hasn't been on?
What is a hesitation exactly? Do the RPM's increase during the gear change? Does the car hang on to 2nd gear longer than normal before shifting into 3rd gear? What transmission fluid do you normally use? Have you towed or hauled anything recently?
No, the MIL hasn't been on since the catalytic converter died on me about 20k miles ago. I haven't towed or hauled anything, driving habits are pretty dull--to and from work, mix of highway and city. ATF changes have been done at the dealer, so I would hope they use the right stuff.
The hesitation is--when it is shifting out of 2nd when the car is in D, at about 2500 rpm, the engine revs up to about 3000 rpm, the cars slows slightly, and then it switches into 3rd with a slight jolt as it engages. The strange thing to me is that when I try to get it to change gears at lower rpm or higher rpms, it doesn't hesitate as above. It switches gears just fine. Just seems to be that 2-3k rpm range has the problem.

It's odd that you claim the vehicle is slipping, but there is no input/output variation code to indicate that any slipping is occurring.
I doubt that it will help, but have you tried resetting the ECM?
I haven't tried the reset yet. I'll give that a shot this evening and see if that helps. Since the drain and fill, the prob is almost not noticable (I might be a little hyper-sensitive to it right now...).

Thanks for the suggestions.
You might have a solenoid that's sticky. That would explain why fresh tranmission fluid seems to have helped.
