Since purchasing this 2010 LS460, 3 months ago I've noticed that in low gear the transmission "slips" or at least that's what if feels like. Usually this happens in 2nd gear for me and when I slow down by braking to turn a corner, for example, pressing on the excellorator will give me high RPM's without actually doing anything for a moment and then it engages. It's not a "jerk" motion when it does, but pretty smooth. Is this normal behavior or does this sound like the beginning of a very expensive problem?

 

Sounds normal, lots of Toyota & Lexus have this, where it fells like power is cut when turning hard. You might need to so zero point calibration, which has solved this issue for me in the past. Also change the Trans fluid if the car has more than 50000 miles.

 

Normal , Just feels that way
