At higher mileages, (125,000-150,000) the automatic transmission may not shift correctly. This can be caused by the throttle position sensor being out of adjustment or a shift solenoid needing to be replaced. Typically the transmission does not need to be completely overhauled.Google+

Toyota Camry Automatic Transmission May Not Shift Correctly at High Mileages
Toyota Camry Problem
Drive Trains Affected: Automatic Transmission, FWD
Average Mileage: 169,995 mi (19,700 mi - 378,000 mi)
Had the transmission pan replaced (will look up and give exact details when I have records with me) and afterward I notice the auto transmission does not shift properly. I can be at 60 mph on the freeway and still in second gear. I have to ease speed down to around 50-55 mph to hear the transmission shift. Prior to the transmission service I had no problems with the transmission shifting properly.

Car shifts into 1st, 2nd, 3rd and into overdrive before the car reaches 30 MPH. It can be shifted manually into all gears and the engine reaches full RPMs in all gears. Throttle position sensor has been replaced twice with Advance Auto an once with a OEM sensor. Check engine light remains on and shift problem continues.
Any suggestions will be welcomed.

The engine is idling higher than normal. when at high speed, the transmission is not shifting
Ok, since I have had the car(couple of months now-172k when I got it) First shifts great, 2nd sort of hesitates but shifts(not brut but slight clunk), then 3rd will stay at 3000 for periods of time. Sometimes I let off the gas and it won't shift like it's a manual driven car, but other times it will shift after it stays at the 3k mark for about... 15 seconds.
This Toyota is undestructable! Still going strong with just regular oil changes, brake pads and, oh yes, a couple of transmission fluid flushes! Super reliable, safe, pulls strong and confortable ride. Now it is having a hard time shifting to high gear and I am troubleshooting the 2 shift solenoids. Hope that's all it is. Had to replace the shift selector switch on the transmission. It finally wore out! Now possibly time for the shift solenoids next to it!!! Not bad though for this many miles (230K) without rebuilding anything.

Car wouldn't upshift through the gears. Didn't fix. Ended up getting a 2012 Toyota Camry.

After hveing the gasket replaced on my transmission pan, which the dealer did twice as I had taken the car in at intervals to have a good checkup and the car somehow had the gasket in the transmission pan replaced. I then read on www.familycar.com\transmission.htm "if a non-computer controller transmission is shifting too early or too late, it may require an adjustement to the throttle cable. Since throttle cables rarely go out of adustment on their own or due to wear and tear, these mis-adjustments are usuallydue to other repair work or damage from an accident. If the vehicle has a vecuum modulator instead of a throttle cable, there is an adjustment that can be made using an adjustment crew in some modulator designs.....hope this helps
