2006 GX470, ~65k mi. When shifting from P to R, P to D, or R to D, the transmission often (but not always) seems to have to think about it a while. When it shifts fine it takes about 1sec for the transmission to change gears. When it's being cranky it takes ~4secs. There are no other symptoms.
View 7 RepliesI have a 2005 2.5 vw jetta.
It has 150,000 miles....the cars been working just fine untill DEC of last year. I had the dealer check the transmission fluid and they said it was low....so they flushed and refilled the transmission oil...they didnt see any metal but that didnt fix the problem.....
Now i have the car not shifting correctly ....theres a delay when shifting in all gears but it is intermittent, sometimes it shifts hard and sometimes you can just baby the throttle and it wont shift as hard.....once on the freeway the car runs fine......but when coming to a stop you can feel the downshifting.....
I figured it has something to do with the valve body....my concern is the dealerships have quoted me 2000$ to replace the valve-body....the cars paid for and was wondering if i should just move onto a different jetta or fix this one?
If i fix the valve body will this jetta have the same issue later? Also i do have the vacuum pump leaking engine oil....not much can this be fixed while doing the valve body job???
I have a 2008 Accent (base model for the most part, no C/C), and my transmission seems to be slipping a bit. The symptoms are: slow acceleration, a delay in gear shifting, and after the 30MPH mark, it takes forever to get up to anything near 60. I just wanted to know if it's a simple solution such as topping off the transmission fluid, or if it's a bigger issue.
View 5 RepliesWife's Santa Fe has an issue with it's shift points. Its a 2002 with 148K on it, never has had a CEL, fluid is changed every 60K. Over the past few months the time it takes to shift through the gears is getting longer. What I am describing is not an actual delay between the gears, but rather how long it is starting to take to get the tranny to even shift. Sort of like how a vehicle shifts through its gears when your at a stop, and put the pedal to the floor and just hold it. it makes no difference if your barely on the gas or half way down, still takes a way longer time that it should to shift. It is slightly worse when cold, but still does it when warm. Is there some kind of temp sensor or vacuum line or whatnot that would cause something like this? When it does finally shift, its normal, tight, no slippage or delay. truck runs great other than this.
View 7 RepliesI just bought my first Lexus, picked up a 2008 GX 470 with only 35k miles!
I just had the TSB for the "Clunk" issue fixed and I had a tire sensor that was leaking and had that fixed.
The ONLY other issue I am having is that there is a vibration at between 1250-2000 RPM and it's most prevalent at 1500 RPM, but it is gone above 2000 RPM. This happens while in park and hitting the accelerator to get to those RPM and it happens in all gears while driving, which is especially annoying because the SUV typically is sitting right at 1500 RPM while driving.
The Lexus dealer thought the driveshaft TSB would take care of the vibration, but it didn't.
My friend has a 2007 accent with a manual transmission they said that they were driving and the transmission stopped shifting gears. The clutch pedal still has pressure so I don't think it is a master or slave cylinder issue. They freaked out and turned off the car and now the car will not start up again. Have any of you experienced anything like this before or know on this car where to start looking? I think the issue with not being able to switch gears could be a pressure plate issue but this would not cause the car not to start.
View 6 RepliesLately I have noticed that the transmission is not shifting smoothly in the lower gears. I have 114K on there. Spoke to my service manager and he mentioned that it may need calibration. Doesn't sound right after all the miles?
View 5 RepliesI have a 2006 Chevy 2500HD with about 180000 miles. All of a sudden the transmission is shifting extremely hard at times. It doesn't shift this way all the time. What could be causing this problem? It doesn't have to be under hard acceleration either when it does shift hard. It sometimes is during hard accelerating and sometimes it is under very little acceleration, but as I said it doesn't do it every time. When it does shift hard, it seems to do it in all gears.
View 1 RepliesI am coming from a 2001 Acura CL-S which is a 5 speed automatic, and that car wouldnt' change gears that quickly. I understand cars today change gears frequently to be in the best gear for fuel efficiency?
But I feel like my ES350 changes gears so much, even at the slightest speed change. Is this normal -perhaps it's because I haven't driven a new car since my 2001, 12 years ago! Even the slightest press on the pedal will downshift the car and into the lower gear, even on ECO setting. On my Acura, pressing lightly on the accel pedal didn't result in a lower gear, as I know the engine had more than enough torque.
I also love reliability, and this makes me think the transmission would have a shorter life span with all the shifting. I still haven't asked my dealer about how often to do tranny fluid changes (which I know is a different thread altogether about discussions about "lifetime" fluid).
I have a 97 4runner Automatic that as your driving it hesitates between shifting its gears. Most prominently happens around 80km/hr shifting between gears.
Its a sort of soft sputtering/jerking motion momentarily. It does shift into the gear and does drive fine once its in the gear. My check engine light is on as well now....
Is it normal to feel resistance and binding of gears when shifting into L or H, when regular shifter is in neutral? One Lexus dealer technician said no, a different Lexus dealer said yes, and a 20-year private transmission shop technician said yes; the "yes" technicians said its because the gears are not synchronized and will grind and bind a little when shifting into L or H on the 4 wheel drive shifter. Car is a 2007 GX 470 and runs great.
View 14 RepliesI 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.
I'm having problems with my automatic transmission in a 2002 Saturn SL. About 2 months ago I noticed a delay when I would put my saturn in reverse and it would sort of kick into gear after a few seconds (up to 10seconds sometimes). I wasn't worried much about this at first until another problem started happening. Between second and third gear it seems to be shifting slow/hard(?). I can feel where it wants to shift, but its slow to shift and actual revs high before shifting down. The problem doesn't always exist, and some days its more then others. We took it to get a transmission fluid/filter change and this didn't solve the problem. Took it back for a transmission diagnositc and GM told us we need to replace the transmission or do an overhaul. They didn't explain why really though- no clear answer. I've heard everything from the torque converter to a solenoid problem.
View 3 RepliesI just purchased a used a Lexus GX470. The transmission seems to do something fairly consistently that seemed unusual to us, but we are new to this car so I'm not sure if it is normal, abnormal, or a sign of something big to come.
When starting from a complete stop, upon removing your foot from the brake, there is a noticeable mini-surge in the engine as the transmission engages, and the sensation seems to repeat when the transmission is disengaging as you brake to stop.
Does this sound normal? From searching on google, I have read that there are issues with "hard shifting" but this does not seem to happen with shifting...just when the transmission engages or disengages, and it isn't a big 'bump' as much as a mini-surge. I have also read where it could be related to something electrical such as the air conditioner.
The car is under warranty, but the service department notes no error codes when they scanned the engine.
I have had my 2007 GX for 5 months now. I have discovered the "clunk" issue and had the dealership replace the driveshaft. I want to start a new thread because I have a different clunk. The new driveshaft has fixed my clunk issue at a stop but I have one more. While driving in the city or leaving the highway on the exit ramp (transmission is in overdrive) and I press the accelerator I get a clunk.
This only happens when the transmission is shifting out of overdrive. I can repeat this clunk while driving around 30-40 mph. I will coast a bit then accelerate enough that it wants to shift out of overdrive and then "clunk". It sounds loud but not much of a jerk. I have 85K on it and did not perform any fluid changes in the drive train yet. Transmission is sealed so not sure if it is worth changing or just leave it and drive nice so it don't clunk.
I have had an issue with my GX470 almost since I bought it in 2008. It will sometimes not engage in drive after backing out of a parking space.
It usually happens when it is warm and the car has been driving for awhile then I park for lunch or an errand. I come back start up the car put it into reverse backout of the car space and nothing for a good 5-6 seconds. Seems a lot longer when cars are waiting to take your space and honking.
Anyway I have been reporting it to Lexus at every service and getting a no trouble found. Over time it is occurring more regularly and it even happened at the dealership but of course I was the only one in my car at the time.
So the other day I was listening to the radio, and all of sudden no more audio.. After some troubleshooting, and some reading. I am thinking it's the levinson amp. I have a few questions:
First where is the best place to buy a replacement.
I assume it's the piece under the passenger seat and it's as simple as undoing the bolts and swapping out the cables..
I did run the diagnostic with the holding info, and flicker the lights and everything came up as "ok". I just need to get audio going in this thing again for as cheap as possible!
2004 LX470 in galactic grey, grey leather, NAV and ML
2006 GX470 in black/grey with the sport package, Nav.
Each is in perfect condition, flawless in maintenance, and he has given me the option of choosing one to keep, and he will keep the other.
Input? I really don't know which to choose!
The whole right side speakers do not work on my 2006 gx470, its not the control screen it the speakers. I hear it could be the amp? Any info out there?
View 4 RepliesHaving bought my 06 GX 470 only a few months ago, we're encountering 90-degree-plus days for the first time. There is an unusually loud noise from the engine that I'm almost sure is cooling fan noise. It occurs after running in the heat of the day. It's not mechanical noise, but a loud roar like that of a large truck engine. Is this typical for these models in the heat?
View 10 RepliesCan the instument cluster on my GX 470 be relaced with a used unit? Will the miles be retained from the computer or will I have to some how have them matched to the old odometer? I do not want to have a mileage unknown unit nor do I want to have to buy a new cluster from the dealer.
