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 searched and couldn't find anything related. So hoping you guys can help.
I have a 2005 4Cyl Camry - transmission replaced under warranty at 89K. The car now has 150K and we've been having a couple tranny issues recently.
Most annoying/alarming - When the car is warm and you shift from Park to Drive the car hesitates for 3-5 seconds before it slams into Drive.
Now the car thew a CEL about a month ago. Took into the Toyota and they took a look at it. Said the code was related to 3 Shift Sensor Solenoids (which didn't make sense) so they cleared the codes and took the car for a test drive and said "all clear" car is fine and there's nothing wrong.
But there is something wrong. I'm wondering if one of the sensors is going bad and it just isn't throwing a code yet.
Anyone dealt with something similar? If so can it be fixed DIY?
Yeah I had the dealer do a flush and fill at the same time...checked the fluid the other day. It still looks and smells OK and is still full...Just shifts hard into drive when it's hot. Perhaps they didn't use the correct AT fluid??

well here i go again...
"Back in my day".....
we had transmissions with "servos" inside that when fluid would fill the bore, the piston would move and apply whatever band was called for..when this conditioned happened as you descried yours, it tells me of an internal fluid leak. there were and maybe still are, rubber sealing rings on those servos...they leak, fluid gets past them till enough time passes (3-5 seconds) and the servo moves...
so, only from "past experiences"...i am going with an internal fluid leak.
the fix..?? simple...rebuild the transmission.
i would suggest you go to a REAL transmission shop..out here we have Cottman and AAMCO, and they do a FREE diagnostic test where they connect gauges to the transmission and read the fluid outputs, etc,etc.....dealerships typically DO NOT HAVE a transmission mechanic there..usually ALL transmission work is taken to the shops i just told you about..!!! so they (the dealer mechanics) would not know their ass from their elbow about transmissions.

The statement about Toyota dealer techs is completely false. I'm in a Toyota tech training program "T-TEN" And we actually tear apart Toyota transmissions and put them back together. I've worked on the U660 trans myself.

05's got the Aisin U250 series 5 speed using dino Mobil-3309 (T-IV) ATF. The older A-series were better transmissions.
Maybe drop the pan and replace the filter as a final step before taking it to a transmission shop. I'd refill with Valvoline MaxLife synthetic ATF that's suitable for T-IV.
Check the ATRA member shop finder and see if you can find a reputable shop. Don't just take it to a corner garage. http://www.atra.com/shopfinder
Unless you don't mind pulling the valve body and solenoids. If so check your local Transtar Industries for parts: http://www.transtar1.com/locations.asp

if you GO BACK and RE-READ what I HAD SAID.....I NEVER SAID TOYOTA dealer techs......
i did NOT single out Toyota mechanics..i "generalized" by saying this...

now for YOUR INFORMATION, given time involved and flat rate shops and OVER ALL COSTS of transmission repairs, and THE LACK of specific training to the transmissions, dealers would "ordinarily" farm out transmission work to a REAL transmission shop where their specialty WAS transmissions only....no engine repairs, no brake work, no suspension work, etc,etc..
so IF YOU are going through training for transmission repairs, good for you and good for Toyota to have such a training program.....
in a transmission shop, you would have "the installer" who's job function was to remove then re-install the transmission. then you would have the transmission mechanic who would tear it apart, diagnose in depth needed repairs, and rebuild the transmission. again, transmission shops can do this job FASTER and at a better price for the dealer, who would get "discounted pricing" on the repairs, but yet mark up a few percentage points to make a small profit for taking the car to a transmission shop..there WILL STILL BE a warranty the dealer will cover.
further still i did start off by saying...."back in my day".....i think i pretty much covered my ass in stating my opinion on this matter.

Hello JohnGD,
When You mention the 05's; are You refering to the 5th. generation Camrys (2002 - 2006) or only the 2005 Camry?
I have a 2003 Camry and it has a 4 speed automatic transmission, not a 5 speed auto trans. Do You know if the latter 5th. generation Camrys were upgraded with a 5 speed auto transmission. Thanks.
The 05-09 2.4L have the 5-speed Aisin U250E transmission. The 02-04 have the 4-speed U241E transmission.
The U241 IIRC has a fluid circuit design defect that can cause two gears to be engaged at the same time, causing a clunk during some shifts. The U250E made an improvement on it, but I think it still has other problems that owners experienced.
Overall I'm not a fan of the U-series.

I have that same 'clunk' about once a year in my '05. I've experienced it in my aunt's '05 Avalon too, which also has a U-series tranny. I'm almost 7 years in and so far so good. Still shifts like new and I just change the ATF every other year by doing a drain/refill.

In one of your posts you wanted to see the victims of transmission flush. Here is one more...
Keep promoting it - you paid a big buck for it!

when done PROPERLY AND ON A REGULAR BASIS, having the transmission flushed and refilled will lessen the chances for varnish to build up inside a transmission. heat is the MAJOR KILLER of transmissions. if we were to allow the varnish to build up, poor shifting will result. any "servo" that needs to move freely in it's bore will jam up. (this also includes the valve body too by the way), many times, due to the varnish, the seals around a servo will tear, allowing for leakage, and lack of the bands applying when they are supposed to.
one simply cannot have "pre-existing" problems and think that the flushing will cure all the problems.
i believe the original poster had pre-existing problems he was not aware of, or ignored.
and I WILL CONTINUE to promote fluid flushing, over a simple dropping of the pan, which DOES NOT replace nearly 100% of the fluid, and i will also CONTINUE to push for a regular transmission service at the very least, every two years for "normal driving", or EVERY YEAR for Heavy Duty driving, like pulling a trailer, OR carrying heavy weights, such as having passengers every day, day in, day out, like a "car pooling" situation.
Was the 4-speed U241E transmission for the 2002-2004 Camrys used in "both" the 4 cylinder and 6 cylinder Camrys or did they use 2 different model transmissions depending on the engine size? Thank You.

OP was discussing 4-cyl so that's all I mentioned.
The 02-03 V6 use U140E and has the same fluid circuit design flaw (basically the same series as the 240). And the 04-05 V6 use the U151E. The U151F used on the Lexus has IIRC a different differential design and I recall some problems with it failing early. But I don't think the 151E has the same differential (?) flaw as the 151F.
Consider switching to Valvoline MaxLife fully synthetic ATF. It's suitable for both T-IV and WS and change out the felt filter too.
