automatic manual
hey,
I dont know if it is really safe to downshift on normal basis. What going to happen to tranny if i continue to do this.

Definitely not a good idea. I wouldn't worry so much about the clutch as I would the gears, misc. small things in the transmission, the axles, and the rear diff. These cars do not "blip on downshift" as a real semi-auto transmission does, and you obviously cant put in the clutch pedal to blip I believe that the paddles were more of a marketing device, but I do admit that in a drag race I would use the paddles because the shift is a bit firmer.

I only have been upshifting and didnt do any downshifting. I thought about forum so i asked here to be safe before trying to do on my lexus. Normally, i stop and shift to lowest gear and drive and upshift.

on a personal note today i was driving and pulled up next to a friend bumped the shifter into neutral and floored it to rev the engine. the gear didnt disengage prior to my lead foot getting let loose and i ended up with this embarrassing lurch forwards before the car went into neutral

Oh okay, I dont have the e shift which it would be useful. I mean the shifter on the console. Is it okay to do same thing?

Alot cheaper to replace brake pads than the clutches in the trans... and earlier poster, the gears in an auto are constant mesh/always engaged... they don't 'change'.... different clutches apply to engage the already meshed gears... only additional wear downshifting the trans would be to the clutches... (well, backloading the gears, but that is insignificant)... Manual upshifting (basically) affects nothing, manual downshifting (without a perfect blip) doubles the wear on the clutches.... just sayin'... I think Jeff will agree??

What does it feel like when the clutches wear in an auto transmission? For all I know mine are shot to $ hit! lol

at some point, they will simply start to slip.... or chatter during engagement (at the shift)... just like a manual trans with smoked clutch feels... I think these transmission have a good reputation for longevity, but manually downshifting each gear everytime you slow down is just not something I'd be comfortable doing.... it would feel like unecessary abuse to me... not that it really is.... more like unecessary wear... brake pads are cheap and engineered as a serviceable/replaceable part.... clutch packs are not...

Not sure which model you have but only '98-'00 GS400's AND only '01-'05 GS300's came with E-shift. So that is roughly half the cars (or less) made from '98 - '05 with the E-shift.
