Hey guys! I bought a used automatic, 2015 Scion tC with 17k miles a few months ago, I had a drain and fill at Toyota on the tranny fluid. About a week later I was leaving work and kinda punched it to get into the lane, that’s when the car stayed at 3500 rpms for about 5 seconds, I let my foot off the gas but it stayed high, as if it was waiting for me to punch it more, then it down shifted. I wasn’t sure if this is an issue with the tranny or just a one time fluke, hasn’t happened before. Toyota said everything looked good but idk, I haven’t had a car in 11 years. I chose Scion because of the Toyota name behind it and it was in my price range, looks brand new.

That sure sounds like slip.

Okay so what would be my next course of action for this? I’m just hoping it’s not a huge issue.

Have you verified it has the proper amount of fluid?

Did you get any kind of warranty?
If no I would look around for the most reputable tranny shop in the area.

WarrenGK - was it slip? If your speed did not go down during the episode, it's not slip. It is a bit of laziness in the transmission downshift, and it might have been an isolated incident.

What was the ambient temperature on the day this happened? How many minutes had passed between the time you started the car and you punched the accelerator? Toyota transmissions tend to push their shift points considerably higher when cold compared to when they are fully warmed up.

Looking on the net, I see that your engine, 4 cylinder AF-FE, runs out of torque at 6700 rpm. You were well below that (and it would behoove you to remain below that). Wikipedia tells me your AT is "6-speed automatic with manual shift mode" -- any chance you somehow got into that mode?

If you don't have an owner's manual (which will tell you how to get into and out of manual mode):

Hey there! So I haven’t verified the fluid amount, it’s a sealed transmission, Toyota states that they filled it with 4qts of world standard fluid. I did purchase a extended warranty when I purchased the car, although not through Toyota, I have a deductible of $100 per shop visit so may end up doing that. My paper works from the drain and fill shows no tranny leaks or anything out of the normal.

They might not admit a problem. That's the reason I say to have a good trusted shop look at it.

If you have a problem that's the alternate route that could be needed. Get it on paper then you have ammo to return with.

and kinda punched it to get into the lane,

It's the car maintaining the rpms in case you need the punch it again. Most cars will do that for a few moments after you floor the accelerator in the chance you need to do it again, there's no shift lag to prevent a quick take-up.
