Lexus RX 2004-09 :: RX350 Transmission - Engine RPM Revs Too High
May 4, 2009
My 2007 RX350 has 14500 mlles. After almost coming to a stop (5mph) and at times that I need to accelerate quickly while traveling at approx 30mph the transmission wants to hunt for the proper gear. ILO downshifting to the next lowest gear it does nothing but hunts for a second (seems like a minute with traffic approaching) then grabs a gear. Engine RPM revs naturally but too high. Dealer states this is normal for the hunting action. The vehicle is perfect other than this one small problem.

1983 chevy c10I bought this old truck about a week ago and I noticed a few things right from the start. Engine revs kind of high before the transmission engages (about 1,200+ rpms).at highway speed the truck shakes and vibrates really bad at times. the steering wheel doesn't vibrate so I dont think it`s ball joints or tie rods.The truck barely goes backwards when in reverse, the engine revs high (over 2000 rpm) but the truck barely moves backwards.It almost feels like the emergency brake is on.
yesterday the truck (transmission?) started slipping and then it stopped working. I was stopped on the side of the road and this old guy stopped.I told him what happened and he said it was probably the transmission but he knew a way to get it working again long enough to get me home. He picked up a handful of sand from the side of the road and put it in the transmission dip stick hole and then poured half a bottle of brake fluid in.He said the transmission is gone anyway so the sand and brake fluid wont do it any more harm.The truck ran again but not far enough to get me home I had to get it towed. Now I am wondering if it really was the transmission and not just the torque converter. I guess it doesn't matter now because the transmission is probably toast now.

I have a 2008 RX350 AWD with only 500 miles on it so far and I am starting to get concerned about what seems to be excessive slipping or a delay in response in the trans. Under normal forward driving the trans seems to shift very smooth. The problem occurs under situations where I am coming to a near stop, basically coasting, and then have to accelerate again to continue forward. This could be in a slow moving traffic type situation or when maneuvering through a parking lot. When I try to execute a small increase in speed the engine revs but the trans doesn't respond.
It's as though it's in neutral and unable to decide which gear it should be in. After a 2 to as long as a 5 second delay it finally engages and moves forward. The condition is even worse if I am heading into a slight incline. Once it is engaged everything is fine and the subsequent shifts are very smooth. When starting from a complete stop it works perfectly. I've never had a transmission slip this much in any vehicle. There was one situation where I was almost broadsided because the RX delayed in moving forward.
I realize this is a subjective call but I am trying to determine what level of slipping in the trans is considered normal under the conditions I've described. I have searched and read past threads about issues with the earlier model years but I thought they were resolved by now. I haven't taken the RX in for service yet but I fear I will get the standard - everything is working as designed - answer from my dealership.

When the car is cold it runs fine. After driving for 10-15 minutes the transmission slips, while driving the engine revs and then engages again.I have only noticed the disengaging/engaging as speeds less than 40 MPH. When the car is in neutral and placed into drive it may take several seconds to engage which happens about 60% of the time. Could this be a sensor failure or time for a new transmission?

My 2007 RX350 popped the check engine light. Stopped at an auto parts store and read the codes. They were:
P0300 P0301 P0302 P0303 P0304 P0305 P0306
C0215 C1201 C01223
U0073 UI0123 U0124 U0125
I am most concerned with the P03xx codes. Could this be one common part? I'm on the road about 1500 miles from home.

I just purchased an 07 RX 350 with a salvage title. I'm going to fix it up and drive it but I'm trying to figure out why it won't start. It was hit in the front driver side corner, bent the radiator support and crushed the bumper and head light, but that is about the extent of the damage. I tried charging the battery and I get power inside and the other headlight seems very bright, but when I try to turn it over, I can hear what I think is the fuel pump engage but the engine doesn't turn over and there is no noise from the starter. Is there a sensor or something that would be stopping it?

I only use AC in the summer around here, not year 'round. When I turn it on, I notice that the engine revs higher when turning the compressor, which cycles on and off. It's only a few hundred RPM, but it's quite noticeable and will make the truck surge forward when sitting at a traffic light. The dealer says this is how the AC works on a GX, so I've gotten used to it.

My auto transmission is sticky at times. This usually happens after an hour of driving doesn't happen all the time. The gears start to change at high Rpms like 5 to 6k. It's real annoying. Otherwise the tranny is very smooth , like butter . Shifts into all gears.

I have a 2008 RX350 with 68k on the clock. Received a check engine light for random misfire (P0300) and misfire on Cylinder 4 (P0304), Cylinder ,5 (P0305) ,Cylinder 6 (P0306). Question is what will be causing this to happen. I thought about changing the spark plugs to see if this is possibly the cause. but what else should i be checking?

I have a 2002 lancer. Here is my problem which has been occurring for the past 4 years: Transmission? When in stop and go traffic it feels like it is reving very high. Sometimes it feels like it gets stuck in a gear because it doesn?t accelerate at the moment the gas is being pushed and then it thrusts forward. When stopped completely the rpm varies between the 1 and 2. When stopped in traffic, when the brake is applied, sometimes you can feel the car wanting to thrust forward, and you have to hold your foot on the brake very firmly/hard. Maybe twice in the past 2 or 3 years, it has thrust forwarded while I thought i had my foot on the brake, but maybe I just needed to push super harder thna I was. When put in park it the rpm is usually at the 2 maybe 3, so when put in park it suddenly feels like the gear is very high...
When the car is turned off, it shakes and seems like it was thrown out of gear. The engine always feels very very warm after all this happens. I have mentioned this to a couple of mechanics, but they never take it seriously, and thus never find a problem. When they drive it, it does not exhibit the problem, because it only happens in stop and go traffic, and or when it has been running/driven around for a long time.

Three weeks ago got in the car, started it and it immediately began to vibrate with high revs and white smoke pouring out and would not stop. Turned it off and restarted it with same results. Then I drove it around the block and it finally stopped. This has not occurred since. Took it to dealer and they could find anything wrong, since not any of the warning lights came on during this occurrence.
It is a 2008 LS with just 38,000 miles on it.

I have a 2015 Lexus rx 350 it is not all wheel drive. When I put the transmission in drive or reverse I have what I would call a double engagement. It feels like it is going into gear twice. It does not slip it shifts smooth.

I have a 2005 GTI 1.8T with 203K miles, stock except for a MagnaFlow exhaust. My problem arose about a month ago. When I accelerate aggressively and shift from 4th gear to fifth at about 4K RPMs the engine will jump up to 5K RPMs. Happens while shifting from any gear when accelerating hard.
When I push down on the clutch and take my foot off the gas, I get a jump in RPMs. It's kind of like the boost in the turbo is not getting released. I replaced the stock diverter valve with a Forge DV with the splitter. Had no effect on my problem, but now I have that cool sound when I get off the gas.
Could this be the waste gate on the turbo not opening and releasing the boost when I get off the gas? I'm not very familiar with the intricacies of the Turbo functions and the diverter valve.

I recently just purchased a 2011 Lexus RX350 AWD... I would like to ask on the downshift while slowdown the car.... Every once in a while I feel the tranny down shift while slowing down... It's not harsh or anything, but just enough to have a slight feel. Like a backlash? Is this normal? I also have 09 GS350 AWD.. It's so smooth that I can't feel the downshift at all...

I have a MT '12 Golf 2.5L with around 8k miles. I always park with the transmission in neutral. When I first start it up in the morning, the engine revs high, around 1500RPM, so I can clearly hear the engine inside the car. I start it, it revs up and holds, and when I release the clutch I hear what sounds like a rev, but the tach doesn't move.
I believe the GTI doesn't need the clutch depressed for the entire turn over, but the Golf does, so I have to hold it until the engine is running. It may not be a big deal, but I'm just wondering why releasing the clutch in neutral would make a noise. I don't hear it any other time than at start up.

2013 Elantra has occasionally high engine revs at low speed. No check engine light. Transmission is not slipping .... Just high engine revs in traffic at low speed ( under 40 mph).

I have a 2005 Camry and it was stalling while driving occasionally. It had gotten worse, so I cleaned the throttle body as was suggested. Now, when I try to start it, the engine revs really high then goes back down and dies. This is without putting any pressure on the accelerator. What to do next?

I just bought a 2004 prius with 187000 miles for $2,500 and it has a triangle with an exclamation point in it and check engine light on and another symbol on the dash. When I take off it revs like the transmission is slipping and it only will get up to about 50 mph.

V10 - When you shift into tiptronic to brake going downhill, the engine first revs up and then the transmission engages. Sort of an automatic double clutch!

So I tried to launch my 04 accent today, but when I threw it into 2nd, all I got was engine revs. 3rd, 4th, 5th and reverse all work fine, but 1st won't work at all, and I can only get 2nd to work if I shift into 1st before hand. My question is what broke?
