anyone else notice anything weird with their XRS's sport shift in the auto trans?
my 2010 has some weird stuff. if its normal then i find it annoying and dumb, if its not normal then i need Toyota to fix it.
1. when not in sport mode, when i stomp the gas, say from 3rd gear, the trans upshifts and the rpm's jump from 3k to 4k, but the car doesnt seem to pull like i would expect it to, makes the upshift rev nosie but seems as if the trans is slipping. could be my perception, but i feel the car pull harder while leaving from a dead stop all while rpm's stay below 4k.
2. when in sport mode, if you drive and shift say to 4th and leave it there, when you come to a stop the trans will auto down shift but the display still says "4" !! seems like the display is just a "max gear" indicator,,, thats kinda stupid. it will then auto up shift but only to the gear displayed in dash. this just seems really really stupid. if it downshifts automatically then the display should show what gear it is in and then start from 1st making the driver shift the car.
3. shift lag - is it electronics or mechanical that causes the dreadful shift lag when in sport mode? up shifting seems to be twice as long as down shifting. the lag for up shift is really annoying.
overall i think this car has a crappy auto trans setup, maybe part due to electronics control/programming, maybe part due to mechanicals.

anyone else notice this??
I've had the same issues since I got this car less than a year ago. I researched it and came to a conclusion that it was just the result of drive by wire so I figured there's nothing I can do about it. When hitting the gas hard you'd expect a car to take off, but in this case, the rpm goes up but it takes a while for the car to take off which to me seems like fuel is wasted when hitting the gas hard then you decide to brake all of a sudden before the car even accelerates.
marky,
i'm not sure exactly what it is yet. i feel the trans downshift when stomping gas (i dont actually stomp to wot, i press just enough to get the trans to down shift, etc) and see the rpm's go up, but the car just doesnt seem to accelerate like it does when i start from zero. something is very odd with the way this trans works.
i would think its a safety issue over gas issue. if i need to stomp the gas to get out of the way for some reason (which is a big advantage of manual trans) then i expect the car to move, not down shift and rev up and not move hard, etc.
i havent seen too much chatter on this subject though. i wonder if others just dont recognize these "issues" or have simply accepted it as "normal". for me, if maker throws in a sport shift auto then it should at least do basic sport shift functions, like not have big shift lag, and display the correct gear, etc.
i am afraid to bring the car in as i think they'll just say "this is normal" instead of admitting its a problem and having to fix (if a fix is even possible). i will assume the lag issue could be fixed with a ecu update. not really sure about the lack of acceleration when it down shifts and revs, maybe thats mechanical?
are you all talking about manually shifting the gear or just letting the car shift for you?
the sequential auto is not going to shift for you efficiently if you put it on the manual setting, you have to time your RPM properly or your just wasting time.
i almost red-line between shifts to get the most of the gears when manually shifting. you have to treat it like a manual not an automatic on that setting.
if you want it more responsive you need to upgrade the valve body on it to allow more fluid and get a modified torque converter
ploud,
the sport mode (mode wher you can shift manually) will auto shift up/down to/from the selected gear, just as it would do in full auto mode (except full auto uses all gears).when in sport mode i know Acura would take it back to 1st if you came to a stop while in 4th, but the indicator would say "1" and the trans would then stay in 1st. i suspect this Toyota trans simply has a crappy sport mode and/or the ecu was not ideally programmed.
its not a "sport mode" automatic like you think on the acura or other cars , some of them have an auto clutch like the automatic camaro which is like a manual but it just pushes the clutch automatically. our car have the sequential automatic, you can not think of it like the automatic clutch. the torque converter has to build up pressure before it triggers a change of gears on the valve body, if i said that right. so i think your idea of the "sport mode" on the corolla shifting up or down for you properly is the issue since it wasn't made to do that in the first place.
OK, let me see if i can explain this a little better, if anyone have the correct info please feel free to correct me. when you put the XRS auto tranny from the D to S, it automatically set to 4th gear. if you don't touch it after it will shift down and up like a regular auto (not 100% if it will go up to 5th gear) but the shift timing and RPM is not the same as it would be when its on D. So pretty much you really haven't done anything, i believe it might just be a safety feature in case you accidentally push it to S. However if you down shift and up shift like a manual it will perform fine. if you shift to 1st 2nd or 3rd gear it will not auto shift for you unless its on 4th gear. if you don't believe me try it out and watch your RPM.

^ +1. it will not shift itself in higher gear (in S mode) unless you do so. it will just hit the rev limiter. and yes at a stop light you shift into sport it will show 4 and you can take off in it, it will shift normally till it reaches 4th gear then you will be required to tap it to shift to 5th. however at the stop light if you tap it down on 1st, then it wont automatically shift to 2nd until you do so. like others said, just a safety thing, your car cant pickup in 4th and its not a manual which will stall so this is how its designed to work.
thus far the reasoning posted makes sense (mostly safety concerns), what doesnt make sense is how the trans works in sport mode.
once in sport mode it should at least change the display to indicate what gear it is in, and, should not auto up/down shift (except under specific "safety" conditions like low speed, high numerical gear, and throttle position, etc).
so if i come to a stop light in sport mode 4th gear and allow trans to down shift to 1st, i now need to hit the shifter back to 1 so that i can take the rev's to where i want to shift, otherwise the trans just does the normal trans auto up shift..... thats silly, if i wanted that i would just leave it in normal mode.
and i tested, the sport mode auto up/down shift (shifting on its own) seems to be identical to standard auto mode.
besides the annoying shift lag, the way this sport mode has silly operation.
i didnt buy auto trans for the sport mode feature, but, i wasnt expecting this sport mode trans to be like this.
Just get a throttle controller and set it to sports 7 all the way, and you will like it better.
+1. sport 7 on the auto xrs is a very nice experience!! i enjoy driving that more than on my manual with the same setting. no lag, and transmission upshifts/downshifts very quick.
maybe its just me but i find the car very responsive. especially when using the auto like a manual. i can get up 60 to 70 mph when i shift to 3rd gear without red lining my tachometer. only mod i have on the car are TRD springs, TRD front and rear bars. only thing i wish to do next is find a way to disable trac control but keep VSC and ABS working. haven't made up my mind on intake mods, since i might still consider F/I down the road. I am considering to get some 18" rims down the road also. still wish i could find LSD for the auto, pushing 70 to 80 mph on curvy roads are starting to get hairy when VSC and Trac turns on. i still can manage to get 31 to 33 mpg average without stomping hard on the gas but ride the curves hard on my way home at night when the roads are empty.
