Elantra XD (2001-06) :: Automatic Transmission Shifting Erratically

i have a 2001 elantra with 136k. the automatic transmission (which otherwise shifts very smoothly and shows no sign of problems) shifts suddenly and erratically when i'm driving at a constant speed. I'll be traveling along (speed doesn't matter), and it will suddenly downshift, then upshift, then downshift, etc. this started off being very occasional, but now it randomly shifts every 5-10 seconds.

I've changed and checked the fluid, and tried replacing the Input Speed Sensor and the Output Speed sensor...that didn't fix it. it also does not blow a check engine code. I'm convinced there must be a sensor somewhere that is faulty. it really seems as though the transmission is electronically confused.

Passat (B6) :: No Start / Automatic Transmission Not Shifting To Neutral

So yesterday after running an errand I got home, after having dinner I was about to head out and, SURPRISE! The car wouldn't start... The engine doesn't turn, no lights on the gauges when inserting the key, no clicks.... the battery seems fine, as the radio works, the anti-theft/alarm works well, the 2nd key behaves the same way.

This morning, I called VW road side, the tow truck they sent couldn't take the car because it is in a tight spot and we can shift the car to neutral. We tried resetting the ECU by disconnecting the battery without success... What to do??

Santa FE SM (2001-06) :: Transmission Shifting Hard Around 40 Mph On Freeway

I just got a 2004 hyundai santa fe 2.7l 2wd model with only 92k miles that I just bought off of Craigslist anyways when im on flat ground and cruising through town the transmission shifts perfectly. However when i went up an incline to get on the freeway it shifted hard around 40 mph but after i got back on flat ground again I got caught up in bumper to bumper traffic and once it cleared it shifted perfectly all the way to freeway speeds of approximately 70mph. Then after getting off the freeway and picking my friend up when i went to get back on the freeway (another incline) it shifted hard again around 40mph.

Accent LC (2000-05) :: 2001 GL Transmission Shifting Hard Into Drive

I have a 2001 hyundai accent GL the transmission has started shifting hard when it shifts into drive. It shifts fine and smooth from first to second but when it shifts into drive it hits drive hard and sometimes it acts like it doesn't want to shift and if you let up on the gas it will go ahead and shift, but when it shifts to overdrive it seems fine but hits hard when it down shifts back to drive. Also I have noticed a couple times when it goes to shift into drive the engine seems like it revs up some but when you let off the gas it goes ahead and shifts.

Ford F-150 - 1997-2003 :: 2001 - Transmission Is Shifting A Little Hard When It Is Under Strain

2001 Super Crew
2x2 4r70w transmission
417k miles
4.6l

Transmission shifting hard when under strain. My truck has 417k miles and the transmission is shifting a little hard when it is under strain. For example going up hills when in cruise and such forth, no problems otherwise.

My question is kinda weird: Since the fluid has never been changed or added to for that matter (fluid level is correct) , should I change it now or just ride it out? It is still my primary vehicle and runs perfectly!

I have been blessed with this truck since I bought it new
No engine work
Changed DPFE a couple of times
Cleaned throttle body a couple of times
Couple of pairs of shocks
one O2 sensor
alternator

I know its a weird question but could putting new fluid in at this time make more problems?

Accent LC (2000-05) :: 2002 - Hard Shifting Into 2nd Gear (Automatic)

The Accent has been working great recently until the other day when I got in to go to work and now it suddenly shifts very hard into 2nd. And sometimes 3rd.

This problem seems to come and go. Sometimes it will shift smoothly. Other times it will have to reach super high rpm and I will have to let off the gas and slowly accelerate to get it to shift. This seems to happen throughout all the gears and it does not make any difference if overdrive is turned on or off. Also reverse works just fine.

I checked the fluid and it is at the proper level. It does seem to be a little dirty (not burnt) so I am planning on changing the transmission fluid, but something tells me that is not going to solve this issue. It seems like an electrical issue to me. What it could be?

There are no codes at all on the car. Don't know if it matters but the car just turned over to 100k miles. I've been reading on here about all the problems the automatic trannys have in this car but 100k seems a bit early to have any serious transmission problems.

Camry :: 2007 V6 - Automatic Transmission Not Shifting When Very Cold

My 2007 V6 failed me several times on very cold mornings. I start the car, wait about 1 minute and then drove it to a stop sign or red light (still cold). When the light turned green, I tried to proceed, but it was as if the car was in neutral. The car would not move. It was only after about 2-3 minutes, when the car started to warm up that I was able to get a gear. After 5-7 minutes, it was as if nothing happened. I have 97K on the car.

Chevrolet - Silverado1500 :: Automatic Transmission - Rough Shifting

Just this morning I noticed that the first shift my automatic transmission makes is not so smooth. Almost like I'm getting a slight shove from behind. Repeated at every stoplight. I know I'll be calling the dealer tomorrow, but am hoping to get ahead of the curve and be prepared for what it might entail.

Elantra HD (2006-10) :: Automatic Transmission Shifting Rough

I have an automatic 2010 Elantra Touring and I drive 115 miles a day (4 days a week) with it (currently have 38K miles). Part of the drive goes up over an 1100 foot foothill, so I change elevation of about 800 feet on the drive. Over the last two weeks, I have noticed the transmission shifting a little rougher and at higher RPMs (everywhere and not just going up the hill). The transmission fluid level looks good, but I am wondering if I need to change the fluid and filter? Or is there something else I need to look at? I need this car to last another three years and want to make sure I take care of it right. Currently every 3500 miles I change the oil and rotate the tires, but I am just not sure about the transmission.

BMW :: Automatic Transmission - Gears Shifting From 1st To 2nd And 2nd To 3rd But Won't Shift Any Higher

I have a BMW 523i SE AUTO (1997) 2494 Petrol. In auto transmission the gears will shift from 1st to 2nd and 2nd to 3rd but won't shift any higher. In steptronic/manual transmission the gears will shift from 1st to 5th without any problems therefore suggesting that the problem isn't the gearbox itself. Only very occasionally does the shift electronics telltale light appear on the dash, yet the problem with the auto transmission is continuous. A local garage specializing in automatics suggested that it was the gearbox inhibitor. I've today had this changed but the problem still exists.

Toyota - Matrix :: Automatic Transmission Jerks When Up-shifting From Gear One To Two

I have a 2010 Matrix with automatic transmission. 5.5 year old with only 44,000 KM ... The transmission jerks annoyingly when up-shifting from gear one to two. I replaced the transmission oil and had Toyota service confirm there is a problem.

I read that the accumulator should be checked and adjusted as well as the throttle which can be done without removing the transmission, but Toyota tells met hat everything is now electronic and there is nothing to adjust. How to proceed?

Hyundai - Elantra :: 2011 Automatic Transmission / Harsh Shifting

I have been having phantom automatic transmission problems with occasional harsh shifting, mostly up shifting through all the gears but sometimes downshifting. This problem started in May 2014, lasted off and on for several days, and then stopped occurring. There had been a few instances of small drops of fluid on my carport but nothing consistent. Then in September, the problem started again on the same basis: on/off again, nothing consistent. When I couldn’t locate the port under the hood to check the transmission fluid, I took the Elantra to the Boise Hyundai dealership to ask where the trans fluid port was located. My service rep told me that there was no port in the new vehicles and that the transmission fluid was not changed until 100,000 miles at a cost of $400. The service technicians could not find anything wrong with the vehicle when they hooked it up to their computers to check the error codes, and the vehicles would not perform the harsh shifting when they test drove the car. The techs re-set the adaptive points and I was sent on my way. A few days later, the harsh shifting started again on and off, phantom problem. I took the Elantra back into the dealership and told them to keep it for as many days as it took for a tech to drive it home and start it cold in the morning. The transmission did not perform the harsh shifting for the 80 miles the tech drove it home and back to the dealership for three days.

After driving the Elantra another week, the phantom trans problems re-occurred. After surfing the web and checking the Hyundai Customer Forum, all I could find was problems with 2010 Elantra transmissions and my service tech admitted that Hyundai had replaced thousands of 2010 transmissions.

Through the dealership I opened a Case File for my transmission problems because there is something definitely wrong with the vehicle and I want a new transmission, and will press my case to the max. I’ve kept a log since September, noted daily temperatures, and times the trans has performed harsh shifting. I’ve kept the problem to a minimum by letting the car warm up for about 5 minutes and will only drive it when the tachometer needle rests on 1,000 rpms.

Camry 2012+ :: Automatic Transmission - Hesitation During Shifting Gears In 20-30 Mph Range

When my 2012 Camry's automatic transmission shifts gears in the 20-30 mph range, there is a hesitation during the shifting. I had an independent automatic transmission technician test drive my Camry, and he said my transmission had "light throttle 2-3 slide." He also noted a high frequency clicking sound in the vicinity of the transmission while the engine was running, which he said may be a malfunctioning solenoid.

Celica :: 2000 GTS Automatic Transmission - Slight Jerk On Shifting Gears

I bought the car about a week ago, whenever the auto tranny shifts gears there is a slight jerk that old honda autos are known for, my wife's car is a 01 celica gt which I bought 2 months ago and went through castrol import ATF 3x drain n refill method suggested by honda for their auto trany, I attempted the same thing in the gts and the shift jerk went down a little but not by much, the gt auto tranny is so smooth I can't even tell whenever it shifts up or down other then high rpm engine noise when it gets there. Is it the engine being much more powerful then the gt to cause that jerk? Should I try a different fluid? Need to know if theirs is smooth across all gears in any rpm range.
