AT Slipping Issues
 

I'm a new owner of a 2013 Scion FR-S just recently purchased with roughly 24k miles. Recently I've come across a strange issue figured I would share to see if anyone else is experiencing this. (I looked up a couple of threads in the forum and I didn't come across a similar issue.)

Anyways, I'm cruising at 40mph on 6th gear. I downshift to 4th in regular mode and it'll "not catch" as if it’s having slipping issues in 4th gear until I let go of the throttle. Not until I let go of the throttle, it'll shift aggressively into 4th gear. If I don't let go of the throttle long enough it'll just keep revving.
Is anyone having the same issue?

I dont know if it helps, but sometimes i get an issue where ill give it a lot of throttle, the transmission downshifts, the engines revs and then after about 2 seconds it seems to "catch" and accelerate. This is in regular mode (not manual) and scared me a couple of times where traffic was coming up behind me a little fast. Its not exactly the same issue as yours but...

Actually that is exactly whats happening. You just explained it better lol. Do you experience this alot?

Not a lot. It usually only occurs when im about to change lanes to get from behind someone slow and once im in a new lane i have to go almost full throttle to keep from slowing down traffic behind me. I don't do this often, but when i do, it doesn't occur all the time (Maybe 3 times ever, 5000mi total on the odometer). Maybe because it happens in some gears and not in others. I really don't know if its a a mechanical issue or the transmission ECU programming issue but it sometimes scares me when i need it to accelerate and it doesnt. Sorry i cant be of any help.

Come to think of it. My 2010 tacoma (auto) would do something similar i guess. When i slowed down to take a left across traffic, i would give it a lot of throttle and sometimes it would rev the engine and not accelerate for about 1-2 seconds before it finally downshifted and "catched". Turns out, it was a common issue that they had an TSB for. I took it in, they reflashed the trans. ECU and it completely went away.

Easy fix, downshift with the paddles then nail the throttle......yes it has happened to me and that's my fix

Thanks. Ill try that.
