Question about 2005 Lexus Ls 430

1 Answer

The car will not shift into another gear it seems like, it accelerates really slow, does get to about 30 given time to speed up, but if peddle is pressed down to far the RPM's just red line. I have turned the car off and on, tried it in PWR mode and what not, but nothing seems to work, what should i do?

Hi
your automatic transmission may be extremely low on fluid. check the automatic transmission fluid. go get three quarts at auto parts store type dextron II or equivalent.. make sure you get the right type. open the hood, start looking for the transmission fluid dipstick that it shows in the owners manual. if not it may be listed on the dipstick in the engine compartment. start the car set parking brake and check the dipstick with the car running. pull the dipstick out and wipe it off , replace, take it back out and look at the end of the dipstick. there should be fluid on the dipstick and it should be in between or right at the top line. the tranny fluid goes right in that dipstick hole you pulled the dipstick out of it takes a special funnel, theyre usually red, you can pick that up at the auto parts store too, tell them you need a funnel that will fill up the tranny fluid with a tiny end. theyll know. If theres no fluid showing on the dipstick you can safely add one quart of fluid and then let it run a minute and check fluid again. now fill in smaller increments at a time (1/2 cup) untill the fluid shows in between the lines on the dipstick. put a piece of cardboard under the engine overnight to see if its leaking and where. it may need a new gasket or the tranny cooler lines are leaking, study whats loose on the lines or get a haynes or chilton manual and put a new tranny pan gasket on it. its not too hard , just takes time and patience. if theres tranny fluid already in the car I suggest taking it in to be put on a computer for further diagnosis, but this may get you going.
good luck

Why is my transmission shifting down to third on hills while on cruise control when it never used to?


You will need to give specifics of your car, meanwhile I think it is normal, because when ascending, it is only normal for your vehicle to slow down, so a quick response by the accelerator is given to the need to maintain the speed which will in turn trigger the kick-down in ur tranny and send it to the 3rd gear, u will also notice that after it stabilises, the gear will shift into 4th and 5th smoothly.

2001 dodge ram1500 /accelerates slow even w/peddle to the floor


How many miles on that rig? The 4.7 motor is a great motor.

Sounds like a fuel starvation issue. Might also be a trans issue. Does the trans seem to be shifting properly?? Could it be starting in 2nd gear which is the "limp mode" for Chrysler trannies?

Automatic Transmission shifting problems.


i had the same thing...It's the transmission. It's REALLY noticeable shifting from 1st to 2nd gear. I was able to get my transmission fixed for 900 bux. That wasn't even a replacement so i can imagine how much it would cost to get it replaced. The shifting will get worse. By the end of my "experience" it wouldn't shift from 1st to 2nd for about 5 minutes until i drove it around for a bit. THen it would "warm up" to the idea of shifting to 2nd gear.

Put a new transmission in and now the car from 0 to 30 has a slow start. but after that it pulls like its suppose to.


Try putting the transmission in low or 1st gear manually shift it down and try taking off as you accelerate shift it manually to 2 then drive. Did it take off like it should when you put it into low and then shift up or did you feel more power when it was in low if so it sounds like the transmission is not going into low gear but taking off in maybe second gear or even drive. When it takes off in any other gear but low it will start slow and sluggish and as you begain to gain speed it will start feel normal but thats because the speed matches the gear you in at that point.If my assistance was helpful please take the time to rate my assistance thank you.

Car will not accelerate as you shift through the gears (delayed a


i had that problem on a 93 escort and it was because the woodruff key that holds the harmonic balancer in place was broken, the poopy acceleration was because the crank sensor gets its "signal" from cogs on the harmonic balancer, which did not turn at the same speed as the crank shaft because of the drag on the crank pully (crank pully and harmonic balancer are same part)

Seems transmission gear shift problem


Pull the distick and smell the oil. If it's discoloured (black or dark brown) you know the transmission friction plates are burnt and needs a rebuilt.
