Thanks for reply!

The first thing i was guessing was the transmission fluid, but not all the gears should have a "slippery" issue if that would be a fluid?

I made a little research, and some people say that could be a solenoid or ecu issue.

That would be great if topping up a fluid will solve the problem.

At first i want to say hello to everyone as a new user :)

I have a 2007 is250, today i noticed there is something wrong with 1st gear.

When i try to move from 0, car have some kind of delay with it, it fell like a transmission is kinda slippery.

I checked it on manual mode, and after changing from 1st to 2nd engine have more rmp on 2nd than on 1st. (Attached video of that)

That's weird because other gears don't have that problem.

Thanks.
