Hi, may have been mentioned already,but when taking of hard,is it normal for a delay before the rush of power comes on,not sure if this is the tranny,or engine,also how seamless is the tranmision,mine does not jerk,but you can feel the shifts,but they are smooth,

 

I believe the LS uses 2nd gear off the line (correct me if I'm wrong) in the normal mode. If you floor it, it would have to shift down, thereby a slight hesitation with its doing that. Upward shifts is pretty seemless in feel (no jerkyness) but since I'm the driver, I can detect from the slight exhaust note and rev that gears are being changed. Most passengers would not notice any shifts at all.

 

^^ noone ever notices my car shift up or down. Its too smooth and seamless.

 

There's a TSB on the hesitation issue. Lexus dealer will reprogram your car's computer. I had mine done and there's a slight difference.

Or you can just leave your transmission in ECT POWER mode all the time. That way your car is more responsive.

 

you say there is a TSB...

What year, model ???

I too have issues.

the only way the car starts in 2nd gear is if you set the SNOW button on.

 

Take a look at my old "sluggish" thread. I just posted an update... problem solved

 

thanks for the up-date datacom9, will try what you suggest,see if it helps.
does the length effect if the ECU resets,as i did remove the neg terminal a couple of weeks ago to clean the battery terminals,but was of maybe for 10mins

 

I think I read somewhere that 30 minutes unplugged should do it.
