So my ls460 08 has developed some kind of hard shift it happens from shifting from 1st gear to 2nd and 3rd .. tried drain and refill by myeslf but no use when shifting in s mode i dont feel any hard shift or jerk any idea what is going on ?

 

Happens on every shift all the time?

 

It gets ok on its own and it comes back usually on the lower gears

 

sounds like a solenoid issue
