Slipping after transmission fluid change?

Hey everyone I have a 1998 Camry LE 4 cylinder automatic and it's having a problem with the transmission. Last night I changed my transmission fluid, gasket and filter and since then my car's been slow to respond to acceleration. (Side note: The fluid was brown and before changing it my car would sometimes make a clunk sound when shifting gears.) It's important to note that this delay in acceleration only happens for 1-2 seconds until the car shifts into drive and only happens when I'm at a dead stop or just put the car in drive. I learned this is called delayed engagement and was wondering if someone with the same generation of Camry has run into a similar issue and could be of some help. Thanks.

Is the level correct?
What brand filter?
I haven't been able to get an accurate reading on the fluid level yet but the brand is Duralast. I'll try right now to get an accurate reading and update when I'm done.

Edit: the fluid reads low right now but sometimes it's half way up the dipstick. I'll take a picture of it next time it's half way up.

I'm supposed to check it while the engine is running and at operating temperature, right?

What type of Duralast ATF did you use?

Not sure how it's possible for the dipstick to show no fluid at all and also be half way up the dipstick. By "half way up" do you mean half way between the low and full marks, or do you mean literally half way up the dipstick?

I once had delay when shifting in reverse in a Gen 9 Corolla. Simply changing the fluid resolved the issue.

When the dipstick shows over full, is that when the engine is off? The engine should be running (Park or Neutral) on even/flat pavement when you check the fluid level. I check it when the engine is hot and after driving the car on the freeway for a bit. By that point it should be at the full hot mark. If it's hot and you've driven it a while, it should not be half way up the dipstick. If it's running in P or N and hot and the fluid doesn't even register on the dipstick, then you need to add more fluid.

Try this.
Get a rag of some sort. A paper towel will work, but an old shop rag is best. With the engine warmed up, and idling, remove the dipstick a few inches. Then wrap the rag around the dipstick and remove it entirely. Note the bend in the transmission tube, and also note which side of the dipstick follows the bend in the filler tube.

Be sure the dipstick is free of any oil, and then re-insert it exactly same orientation that it came out, and is fully seated. Then remove it, and note the side of the dipstick with the "bottom bend", it will be covered with oil, and will give you the false reading you are seeing. You want to read the fluid on the opposite side of the dipstick.

The dipstick should have no oil on it except at the bottom of the dipstick, and it should show fluid and a distinct line between the fluid and the dipstick.

You might have to try this a couple of times to the hang of it.
Good luck.

Valvoline MaxLife synthetic ATF has solved slipping problems in two of my Toyotas, a 1999 Camry and a 2004 Highlander. I just drained and filled the transmissions at the same time I did oil changes. Since drain and fill only changes some of the fluid, it took three times for each car to resolve the problems.

Adding Lubegard Red also helps. The ATF drain-fill is the recommended way as alternate to straight flush on a high-mileage tranny. If no AT issues, a straight flush as described in the DIY sticky is good. Power flush like ones done at shops is a hit-miss. Valvoline MaxLife is the most used AF fluid. Mobil 1 or Redline brands have also been used.

Flush vs drain-fill will come up as most discussed topic also if you do a Search above. Some even highly debate it. End goal is same... new fluid. Of course, filter replacement or check and replace would be good.

I have been dealing with the same thing for a few weeks trying to get mine perfect. There is trial and error things you have to learn along the way sometimes. This is what I have learned

Operating temperature for my 2000 camry v6 is 70 to 80 celsius. Yours is likely the same do a google for service manual

It can take like 15 full minutes of driving to get it to this temperature.

You can go OVER this temperature through driving for longer or heavy driving up hills etc and the fluid will be higher

I use a 25 dollar temperature gun from lowes pointed at the pan, which is easily identifiable just google a picture.

You do not need to jack the car up you can just point it at it from the front. You have to cycle through the gears for about 10 seconds each

If you have recently put in oil through the dipstick you will likely not be able to get an accurate reading for many hours. I always wait overnight

you can NOT test the cars level without the car on. It will show it being much higher with the car off because when its on it pulls some fluid from that area and gives a lower reading which is the accurate level for testing

do NOT do a POWER flush on an old tranmission which yours is. Not worth the risk, you can ruin it . A REGULAR flush may be ok .
