    Owners have been reporting that while in cruise control the engine/transaxle ECU will actually command a downshift to retard roadspeed going down a hill.

    That's not true for either of my Camrys ('04 with 4-speed auto and '05 with 5-speed auto). If descending a grade at highway speeds with the cruise control on, the car will remain in top gear. If the grade is steep enough, the car's road speed will increase above the set speed.

    ONLY by braking rather firmly will the transmission then downshift into 3rd (for the 4-speed unit) and 4th or 3rd (for the 5-speed unit). Of course, braking cancels the cruise control until the "resume" feature is activated.

    Is it the 2007 DBW model that downshifts? Your models act the way I want a car to do, even when cruise control is "off." I will move the lever to a lower gear if I want the car to downshift, and lose fuel economy in the process.

    I don't believe there's any difference for the '07s, if the transmission is working properly. The Camry has had drive-by-wire since the 2002 models, at least for the 4-cylinder engine.

    The issue of 1-2 second downshift delay/hesitation seems to exist across the industry, more prevalent for FWD and F/AWD but I see posts of these symptoms for Ford, VW, and Honda along with Toyota and Lexus.

    So my cruise control downshift statement may, or may not, have been taken from a Toyota or Lexus post.
  • Three days ago the problem just disapeared and there was very smoth shift in gears.
    However today I used my A/C (I haven't used it during these days) and I noticed that the problem came back.
    Any suggestions?
    Thanks.
  • I still have the same issue that you seemed to have. Most of the time the car does shift smoothly but it does seem on particularly hot days that the shift issue is most prominent. What seems to work for myself is to allow the car to idle for a few minutes - this seems to settle the hard shift somewhat. The only other thing that I can think of is a possible transmission fluid change. I was advised by several mechanics and technicians not to flush the transmission. I usually change the fluid every 20k miles. Hopes this helps. Best regards.
  • My daughter has a 2000 Camry with 95K miles. The check-engine light came on. She took it to the dealer who said she had the following codes:
    P0770 - Shift Solenoid E Malfunction
    P0773 - Shift Solenoid E Electical

    They suggested a new transmission. My daughter took it to a Transmission shop. They tried replacing an external solenoid. Didn't work. They dropped the pan and said there is metal in the fluid. Need to rebuild the transmission. The car runs fine, no shifting problems. He says it has to do with the Torque Converter. Symptoms would be poor gas milage. Said that the external solenoid filled with guck right away. So, is this a common occurance to have a Toyota with less than 100K miles and need a new transmission? I have had Honda's and no problems like this. Will cost $2200, including parts, labor and tax. Any input would be appreciated. Thanks

    Very, very unusual, unless the fluid was never changed. Toyota and GM generally have the most reliable automatics.

    "..unless the fluid was nver changed.."

    Yet another totally unjustified "pilot error" post. Factory "shill"??

    The factory doesn't REQUIRE, nor even recommend, that the ATF be flushed/drained/refilled on my 2001 AWD RX300, EVER...!!

    So I rather doubt if the Camry does.

    ATF can NEVER, by CAREFUL design, be the initial cause of a transaxle failure. ATF can only contribute once it is contaminated or overheated as a result of some failure mode, design flaw, of the transaxle.

    I hope you're not accusing mcdawgg of being a "factory shill?"

    His posts have always been forthright. No matter what the manual says, I think the common wisdom is still to drain and refill the auto tranny fluid at regular intervals, something like 30K to 60K miles. I've already done it once on my '04 Camry (47K miles currently).

    98 camry, 4cyl,auto, car has a problem shifting into overdrive. have to let off the gas and push on the gas to get it to shift. it only happens when the car is getting warm the transmission shop says. they said they could not find anything wrong with it. they said they noticed the engine was losing power when this happens. they think the shifting problem has to do with the engine losing power. the car has 104,xxx miles. only things i had to replace was water pump,timing belt,hoses,thermostat,belts at 7x,xxx miles and just replace the catilytic converter at 103,xxx. the cat was replaced due to the flex pipe getting a hole in it.no codes show up on the engine. any help would be appreciated

    It would not be altogether unusual for an I4 with that many miles to not have enough "GO" power to run at the low engine RPM required in order to operate satisfactorily in OD, most especially after a COLD start.

    Once the engine warms up and the "worn" compression rings expand to more completely seal the cylinder you will have more "go" power.

    How "comfortable" are you that the timing belt was/is properly installed? A few "cogs" off + or - can make a HUGE difference.
  • jhoneyjhoney Posts: 2
    i put it on and the car has always ran good.i was wondering if the timing might be off now. i was wondering if it might have jumped a tooth.we have close to 3x,xxx miles on the timing belt.i am thinking about taking it apart and checking it and installing a new one. might even just get rid of the car and get a new one.
  • i have a 2004 V6 Camry with 45000 miles and i want to do my first drain&refill, should i drop the pan and check the filter at this time

    I'm planning on changing the tranny fluid in my '99 Camry V6 LE which has 60K miles on it. The manual recommends DEXRON III but I see Castrol makes a new Import Multi-vehicle ATF equal to DEXRON III(H) and a whole lot of other ATF fluids. Am I asking for trouble using this product in my '99 Camry?

    Any insight appreciated! :D

  • I brought my 03 camry to the dealership for 30000 mi maintainess. The people at the dealership suggested me to change the transmission fluid, but I said no. I checked my service manual and it doesn't mention to change the fluid at 30000 mi or any milage. I opened the hood and there is a sticker says "No need to change transmission fluid" right beside the transmission fluid deep stick. I am kind of confused about this. I don't mind to spend some money to change the fluid, but on the other hand I don't want to waste my money. I really need your suggestions on this, I should follow the manufacturer's suggestion or the dealership's.

    Thank you in advance for any suggestions and opinions

    I would use the dipstick to check the ATF condition at each oil change interval. If it remains clear and pink then ignore the dealer.
