Jolt While Putting Transmission in Drive Camry 2002 v6 XLE
This happens when the engine is cold. Each morning I start my car I get a quite sensible jolt while putting my car in Drive. This does not happen when I put it in Rear.
After warming the engine up for about 30 seconds while in Park, shifting to Drive goes smoothly but only after I already shifted once (with a jolt).
It's interesting that the shifting is pretty smooth during the day, even if the cars sat in a parking lot for a few hours.
I have your car. And notice how high the idle is when you start the engine cold? The tach on the dash will read about 1200 rpm - this is normal and designed to prevent the engine from stalling until it gets warmer. Once the engine is warm you will see the idle speed drops to about 800 rpm and stays there.
So the higher engine speed when cold is probably what is causing the lurch when you put the trans in drive.
Sometimes if the weather is warm, you can speed the process by blipping the throttle with your foot and the revs will drop a bit faster. Or you can let it warm up for several minutes. It doesn't seem to me theres any practical way to avoid the lurch, it is designed in. Although some clever person reading this post might know a way, somehow!
Yes, I've been wondering a bit about that high idling, too... Well, it's good to hear that my transmission is not in trouble. Thank you for the info.
Now, since you own the same car, I'd like to ask another question. I bought my Camry used a couple of months ago. It's my first Toyota, so I don't know if the sound it makes while accelerating slowly at low speeds is normal or not. First, I thought nothing of it, but now it kind of bothers me. So each time I accelerate just starting to drive my car from standstill, driving slowly in a parking lot, or or driving from an intersection, etc., the engine winds up making this electric turbine whining kind of sound for a couple seconds. it's not a high pitched sound or anything really disturbing. In fact it's kind of soft and muffled and could probably be normal for the Camry engine, yet I can't help wondering if it's supposed to be there.
Another thing I noticed (not related to whining sound) is when I drive off in the morning and start accelerating my RPM goes up almost to 3000 and stays there for about 8 seconds before the tranny finally shifts to a higher gear. I wonder if this behavior is a sign for concern.

I change my transmission fluid every 30,000 miles. Sounds like a fluid change might be worth a try for yours before tearing into it. I also get the whining noise once in a while when accelerate but the sticking at 3,000 rpm for 8 seconds - that sounds unusual. At almost 100,000 on your car i wouldnt do a whole flush, from what i have heard this isnt a good idea onf high mileage transmssions - you will need a 10mm male hex socket to get the drain plug out, and exactly 3 qts of toyota Type IV ATF (it is a dealer only - about $5 a qt - use no other kind). If you want to pull the pan and clean the strainer (the trans uses a reusable metal strainer, not a gauze filter like other trans) then you will also need a new gasket and an additional several quarts of fluid.

Thanks for the info. Why isn't it a good idea to fully flash after 100k miles? It's kinda counter intuitive. I wouldn't be able to to any of this on my own, anyway. Also why can't a 3d party tranny fluid be used?
You should probably drop the pan, clean if off, install a new strainer and refill with ATF to the proper level.
Your Aisin U140E series transmission may be slipping. Low ATF level, restricted strainer, or sticking valve body come to mind.
I don't care much for the U series. They're kinda crappy compared to the older A-series.

If the car has had its ATF fluid changed regularly throughout its life (every 30,000 or 40,000) you might possibly get away with a flush. Personally i would not flush, just based on posts i have read here over the years, by people who flushed high-mileage transmissions for the first-ever fluid change, and then had the trans promptly up and die on them.
The theory from the experts is that if the trans had never had its fluid changed, the crud may sometimes be the only thing making the transmission bands work, and so a flush on an automatic thats never had a fluid change, might kill the trans. I'd try a fluid change and if it goes well after that, then consider a flush if you want to.

Toyota says in the owners manual and on the ATF dipstick of this year Camry and many others, "only use Toyota TIV fluid" , they say transmission slip will result if you use any other kind. Do not use Dexron 2, 3, or Merkon, or anything else but TIV.
(or equivalent). TIV "equivalent" fluid is available now . I have gotten in trouble in the past here for saying stuff like this but i do use the Valvoline equivalent. It says "TIV comaptible/application" right on the bottle. It is only a few cents cheaper but getting to the dealership to buy TIV is a big hassle for me. It works ok and no slippage but Toyota fluid is just, better performing, so i recommend just spend a little bit more and get that if you can. TIV from the dealer cost me $5 a quart 2 years ago.
If you simply do a fluid drain on the 2002 V6 and dont pull the pan, it takes precisely 3 quarts to refill. If you pull the pan, maybe 2 qts more.
