Lexus GS 2013+ :: Transmission Shifts (jerks) A Little Rougher
Jan 25, 2016
So I noticed that my transmission shifts (jerks) a little rougher than the 3 previous Lexi's that I had when shifting into drive or reverse when the car isnt fully warmed up. Is that "normal?" Had 2 ESes and 1 RX and while I do feel a slight lurch, the GS is a bit rough. I usually let the RPM drop to 1k before driving off on warm or cold days.
Separate incident: I recall at one point, I was going reverse, stopped, quickly shifted into drive and gave it some pedal (not full throttle) and felt a noticeable "bang" and violent lurch forward. Could that have hurt the transmission? Is the computer smart enough to prevent damage? I'm thinking this might have been the cause of it.

I have a 2013 ES350 with 3,000 miles on her. Heard a whine coming from the trany as it shifts? To me, it sounds like a power steering pump whine, but not as loud.

A while ago, I acquired a 1991 Mazda 626 automatic (currently 105,000 miles) that now has what appear to be the beginning of transmission issues. It hard shifts from 1st to 2nd - the shift jerks really hard when the car is cold but once I've driven it for 15-20 minutes the hard shift almost disappears completely and stays that way as long as the car is warm - except for stop and go traffic (Seattle traffic) than the hard shift comes back no matter how long I've been driving. The only other shifting issue I notice is on the hills where it seems to shift more frequently than I might expect it too.
Other than what I've described this car is in perfect condition inside and out, as well as engine-wise. My question is on transmissions and whether I should get a rebuilt one. I've taken it to multiple transmission shops and almost all have told me two things 1) I need a new transmission and 2) that the issue is a hard component problem and I could most likely drive this car for months or years without having to replace the transmission - if I want to put up with the rough shifts. They recommended just driving it until the transmission goes out and then replacing it.

Only during the summer, my 2003 Vue transmission jerks and shifts to (I believe) to a higher gear. Mechanic replaced the computer "harness" but it did not solve the problem. The car has little power to accelerate from a stop. I usually pull over, turn off the motor, and restart the vehicle.

I have a 2006 F150 4x4. When the engine an transmission is cold it jerks/ Bogs when it shifts. After it warms up it doesn't jerk to bad sometimes but you can still notice it. Also when it shifts the RPM's drop low causing it to bog and jerk. RPM's will go from 1600 to about 800 when it shifts. It is and auto transmission. Today I wanted to try something so I pressed the button to turn the over drive off. Well it shift real good with the OD Off. Seem like with the OD Off it keeps the RPM's up a little higher so it doesn't bog and jerk. I put an Edge Programmer on it, but that didn't work. Still does the same thing with or without the programmer. I changed all my spark plug and coil packs. Truck goes great until it shifts.

Last week my 2011 KR Diesel with 85k on it stopped downshifting correctly. Basically when the transmission is cold (<150 degrees on the digital gauge for transmission fluid) it jerks everytime it shifts down from 4->3->2->1. Especially 3->2 and 2->1. I have never seen anything like this before. It's almost if you are getting reared ended when it shifts.
If I let it warm up it eventually goes away until it cools down again. I did take into the dealer and they said that a) there is definitely something wrong with the torque converter and b) I might actually need a new transmission which is anywhere between 4-7k depending on if its a reman or new.
This truck is barely broken in and I at this point have not towed a single thing with it. I had thought the transmission was covered up to 100k but it looks like it's only covered to 60 or 75k (I forgot which).
I've opened up a case with Ford but they kicked it back to the dealer. The dealer service manager has been really NICE and is definitely on my side that this SHOULD HAVE NEVER HAPPENED at this mileage. They also don't know how to fix it without pulling apart everything which is a lot of labor.

There is only one thing I don't like about our new SF. The transmission shifts from 4th to 5th gear at approximately 60 km/hr (36 mph +/-) and the rpm's drop to 1500 rpm. Now, when I want to speed up a tad (which is a frequent occurrence when driving around town), there is a pronounced hesitation before it drops back into 4th gear and accelerates.
In 5th gear at 1500 revs, I find that the engine is 'lugging' a bit. Yesterday, I started to compensate for this by changing to manual shifting as soon as the trannie shifted into 4th gear and leaving it there when I was traveling in that 60 kph speed area. For me, this is MUCH better and I quite like doing some of the shifting any way since I spent so many years driving manual transmission equipped cars.
How have others found the car to be when driving around town? Other than that, I really enjoy this car. Easily the most comfortable seats of any car I've ever owned --- their design provides terrific lumbar support and the new cloth material has a great 'feel' to it.

Just experienced something new in my less than a week old 2.0T. This morning was the coldest day since buying it (-15c). I had the block heater plugged in and it started up well. Let the engine run for my usual 30-40 seconds before putting it into gear. Reversed well, but was a bit slow shifting after putting it into 1st.
For the first 5 minutes or so of the drive, the shift were pretty rough. Mostly the shift between 1st and 2nd gear. Things got better after that and were fine for the rest of my trip and also an hour later when I came home.
Is this just a case of a very cold transmission and fluid, or is it something else? I've never owned a car that had such rough shifting in cold weather. Sluggish shifts yes, but not violent like these were.

I just bought a brand new 2013 Elantra! I love the car, but over the past week or so I have started to feel the car's transmission (auto) jerk when it shifts from 3rd to 4th gear. I feel the car hesitate somewhat when going from 3rd and then jerk into 4th gear if that makes any sense. The car has less than 1000 miles and it never did it when I first bought it. The transmission was always smooth until recently. Also, when coasting down the road I feel the car jerk forward when I give it some gas which also feels very strange to me!?

I've always wondered why the transmission automatically shirts to 4th gear when I switch to sport mode! Is this normal??? It's an i4

Lately, I've been having an issue with my 03 GX. It seems when the engine is cold and I back out of my driveway, when I put the truck into D, I feel the usual bump into drive, then it falls off and then a harder bump before I'm able to roll forward. If I don't pay attention and accelerate at the time the transmission seems to drop out of gear momentarily, the truck slams into gear and feels like I granny dropped it.
The truck is coming up on 120K. I've checked the transmission fluid and it is at the correct level.

For the first mile or so on cold mornings, by transmission shifts slowly - sort of a second or two delay until the car warms up. Is this normal?

I would like to replace the transmission fluid in my 2006 SC and do the mod to make shifting firm. I have read a few threads that post pictures of the pressure regulator dial in pre 06 to firm up shifting. One such thread is this. However, I have not come up with any for 06+ transmission.

So I have a swb LS with right at 100k miles. drove great and got tires (same brand same model Continentals as the previous set) put on yesterday - right after that the car got noisier (mechanically, not because of the tires).
When I drive over 25-30mph it's like the car rattles...it starts "rougher" and is audibly noisier in idle now. The water bottle in my cup holder visibly shakes and did not do this before yesterday. What's weird I watched the guys install the tires, they never got close to anywhere under the hood..
Just to rule out the possibility, I had the tires remounted and rebalanced but of course same issue. Sounds like a noisy tranny or like I have an aftermarket muffler..have noticed a slight lag in acceleration (oil change at lexus 600 miles ago).
I got new plugs, air filter, coolant flush, diff fluid flush within the past 3 weeks and had no issue with the car until yesterday. My early suspicion is a motor mount or muffler-exhaust related issue?

I recently started noticing that my engine sounds louder and rougher than usual. I have a 2014 GX with about 25K on it. I get about 800-900rpm on idle and about 1800-1900 when cruising 70-75 mph.
Engine sounding louder all of a sudden. No "check engine" sign pops up. I also took the car to the dealer and mechanic rode with me on surface streets and of course , everything looked normal to him.

Just turned 80k and recently noticed a bit rougher at idle. Other than that all has been fine. Plugs, etc. all original. Engine and VSC Light. Autozone ran the scan which turned up the above stated codes. They are defined as Evaporative emission control system pressure. He said it could be a loose gas cap. Checked it and its tight as a drum.

I picked up a 2013 ES300h last weekend, love the car so far but have a few questions. If its cold in the morning (~50F) the car shakes for a few miles then goes away, I'm thinking its the tranny. I have the same thing happen with my 2014 Highlander (different transmission though).
I'm used to the VW and BMW forums where there are a lot of DIYs to add options that didn't originally come with the car. Is it possible to add the rear automatic sunshade, swap in a radio from a 14/15/16 ES, add ML sound system?

So I recently leased a 2015 GS 350 AWD. The car is great. Love all the features. However, for some reason I feel that the transmission is a bit I rough when it switches gears. I feel the kick. I also noticed a hang up or delay when slowing down. I am coming off a infiniti q50 and the transmission on that car was nice and smooth. Maybe I'm just too sensitive.

Heard a clunk and then have the car feel like something from the inside is trying to stop it when using the paddle shifters in manual mode. Specifically when downshifting from 2 to 1. By the way I did a slight throttle blip, I have done this before with very smooth results but this time it really scared me, I though the transmission broke for a second; when the car did what it did.
