Hey guys I'm new to the forum. Just wondering if anyone else is experiencing this while driving around with the 8 speed is350.

It seems like the transmission is slipping when changing from 3-4-5 under light throttle. The revs shoot up and then it finds the next gear kind of like someone riding the clutch in a manual car.

This used to happen a little during the winter on cold start but its happening more often even in warm weather.

Maybe I'm just crazy but I'm sure its not supposed to be acting this way

Are you able to show us this with a video?

Is this happening while cornering? As there's some transmission logic that holds the gear a bit longer before shifting when it detects a good amount of g-force.

It mostly happens when i start off from a stop at maybe 1/2 throttle and then go to just light throttle around 3rd gear. it shifts normal until i let off and then the revs shoot up maybe 500 rpm before going into the next gear. it looks and sounds odd.

This happens in manual mode as well

I'm trying to upload a video of it now

Woah, that doesn't look normal, and I agree it does sound weird. I don't think I've ever experienced that.

I'd get that checked out by the dealer.

It's booked in at the dealer for Wednesday so hopefully they can help. I really don't remember this happening last year
