Accent LC (2000-05) :: 2001 1.6 Auto - Transmission Thump From 1st To 2nd But Only When Cold

I have a 2001 Hyundai Accent 1.6L GLS with auto transmission.

Recently, I've noticed a hard "tump" in the mornings when it auto shifts from first to second gear. It is loud and VERY noticeable. Aftera bout 7-10 minutes when the car warms completely up, it runs fine with not thump.

I've searched the forums for this and have found no answer.

It still runs fine but the morning "thump" scares the crap out of me and startles me every time.

I purchased the vehicle used a few months ago, it has 175,000 km on it. I don't know the history of the transmission but the car seems to be in really good shape otherwise...

Accent LC (2000-05) :: 2001 - OD Transmission Not Shifting Above 3rd Gear

I am having a few issues with my 2001 accent. I bought this car for around 500 bucks after my friend hit 3 deer with it. At 101,000 miles the transmission went on it and he had it replace with a new one. At about 113k he hit his third deer and parked it. I bought it off him a few years later and its been running great. It died on me one time and it was the crank position sensor. Now I have about a 156k mile on it and it will not go into overdrive.

I have gotten mis fire codes, I know it needs new O2 sensors, and also P0733 Gear 3 Incorrect ratio. The button on the shifter does nothing, If i press it on or off the light does not come on on my dash. I noticed it was not going into OD this last winter if i dropped it into low and shifted to drive it would no longer go into overdrive until i placed it in park and then drive again. Ive been searching everywhere for an answer I was reading one post that it could be the TPS sensor causing issues but i haven't had time to check the voltage.

Accent LC (2000-05) :: 2001 - Transmission Sometimes Downshift From OD To 3rd Gear And Stay There

I have a 2001 Accent with a 1.6. This car is mostly driven by my daughter so I'm translating the symptoms as she has described them to me. The issue appears to be this - when driving at highway speeds the car will sometimes downshift from OD to 3rd gear and stay there. When the problem first started, she would pull off the highway, turn off the car and then restart it - this would appear to "fix" things temporarily, however, as time went on, it would work up to (and including) 3rd gear and not go into OD after a restart.

I've reviewed the various threads on this site describing the 4th gear problem prevalent in the Accent, but in each case that was posted, there was a check-engine-light or at least some diagnostic codes stored that one could refer to - I've scanned this car every time she's been home and there are no DTC's. Should I assume that this is the standard "4th gear" issue and take the pan off for investigation or could this be some other issue such as the speed sensor causing the transmission to limit itself to a max of 3rd gear?

Accent LC (2000-05) :: 2001 - Transmission Physically Downshifts Or Locks Up In 3rd When Let Off The Gas

Car is a 2001 Accent 1.6L 4 door automatic with about 130,000 miles on it.

Transmission shifts correctly into reverse, drive, neutral as well as manually shifting into 2nd and 1st. When in drive I will accelerate perfectly through 1st gear, shifts smoothly into 2nd gear then the problem arises. The car will shift ok into 3rd, but if I let off the gas to coast to a light or a corner, etc, the transmission physically downshifts or locks up in 3rd (like driving a stick, ie the car has drag like the converter is locked instead of freely coasting). It feels like 3rd gear but could be 2nd. When I go to accelerate again without coming to a stop the car has this same feeling of drag with no power and speeds up very slowly (almost like i am pulling something behind the car or am in a gear that is too high). If I give it enough gas to force a downshift it really slams that downshift. While the car accelerates through the rpm range after this downshift it will rev past the normal up-shift rpm until it finally slams into the higher gear. Or if i hold the gas steady at the higher rpm the car will suddenly slam into the higher gear. after all of this nonsense the car drives perfect through to OD. The problem is much worse going uphill and is consistent every time it is driven.

Also, sometimes the car would shake and vibrate when hitting the gas during this "drag feeling" until i let go and did it again. This is pretty random compared to the main problem but also seems to happen while the car is in 2nd or 3rd. This has been happening for about 5 months now and as far as i know was sudden. And on another note it suddenly was shifting fine the other day while driving it. I haven't driven it since then but this completely stumped me, as most problems will do when they magically disappear.

There is no check engine light, OD works fine and the car does not go into the safety mode where it will shift to 3rd gear on the highway. It's city driving that is the real headache (2nd and 3rd gear difficulties). Would the pulse generators cause this? bad TCM? i haven't scanned anything yet but will be within the next few days(at pep boys or similar) as well as ohming out pga and pgb. i have found resistance readings for pgb but nothing for pga, what should pga read? fluid is also within acceptable amount and color.

My initial thoughts were dirty or stuck solenoids/valves in the valve body and i was going to do a filter and fluid change with a quick valve body cleaning and check. But after researching on here I am starting to think it may be electrical. The only reason I put my scenario up is because it seems that everybody else who is having a similar problem is also having the "no reverse" or "shifting into 3rd on the highway" problems while i am not. On a random note, for my own piece of mind, how do the pulse generators work? Are they just reading ticks on a gear cog in the tranny or something? fluid flow?

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.

Accent LC (2000-05) :: 2001 - Transmission Goes Into Fail Safe Mode / No CEL Codes

2001 Accent, 1.5L Automatic with OD, 263,000 km

Transmission goes into Fail Safe Mode but the CEL does not light up and code reader shows no codes. Shifts fine in town,1-2-3-4...4-3-2-1, but on highway when going up inclines (steep), transmission downshifts from Overdrive into 3rd,as i press the accelerator it will downshift into 2nd (as normal), until i reach the top of the incline (3500-4000 rpm) but then as the car levels out on the highway, it will shift back and forth between overdrive and 3rd, (jerky shifting) then finally goes into Fail safe mode, 3000 rpm at 80-90 km/h. Once I shut the car off for a few minutes, the transmission is fine and shifts normally. Fluid levels are good. Why the CEL is not giving code?

Accent LC (2000-05) :: 2001 GL Started Revving When Driving During Traffic Hour - Transmission Slipping?

I have a 2001 Accent GL 1.6L Automatic.

Yesterday it started acting up on the freeway. I was driving about 50 during traffic hour when it started revving. I got off the freeway and moved to 35mph on surface streets, the revving continued at lower speeds but much worse (4-5k rpms going 10-15mpg). Doesn't seem to do it in idle or park. If i shut the car off it'll drive fine for a while then start acting up but when I was driving, after awhile, it did return to normal.

What could cause the problem? TPS? Transmission? Sensor of some sort?

Accent LC (2000-05) :: 2001 - Rumble Type Noise From Rear Of Car

I have a 2001 accent. I have noticed recently that there is a noise coming from the rear of the car. This is a rumble type noise which changes as I speed up or slow down ( It sounds as if it is something to do with the tyres)! I have changed the rear hub assembly and had the wheels aligned but the noise is still present. I have checked the suspension (by pushing down the back of the car) and it appears to be acceptable. Where this noise may be emanating from?

Ford Transmission :: 2001 F250 - Vibration And Grinding Noise When Drive Over A Slight Dip In The Road

2001 F250 7.3L 280k miles. Truck is new to me in the last 6 weeks. Was driving out to Glenwood Springs last night and I got a weird rear end vibration between 79 and 81 mph - couldn't say if it's a new vibration as haven't had the truck long enough. It's sort of still there over 81 but less obvious than bang on 80. Whilst the vibration was there I caught a slight dip in the road that caused a grinding noise to accompany the vibration - I'm guessing because something's was getting extra loading on the upside of the dip.

I'm away from home until Monday so my options are a bit limited, however while crawling around in the dark last night pushing and shoving stuff to see if anything was loose I noticed a couple of things:

Minor leak from pinion seal - but it has flung some spots of oil. Drive shaft 'center bearing'(? U shaped attachment on drive shaft to chassis with rubber bearing?) has play I can push the drive shaft at least a 1/4" with my hand and it seems a little sloppy but I'm no mechanic.

I'm going to check transmission fluid level today and top up if required and check the magnets, such that I can limp home as necessary avoiding 80 and get the diff checked and pinion seal replaced. Does the drive shaft bearing need changing or should it have that much play? I'm assuming it's LSD on the rear?

Accent LC (2000-05) :: 2001 - Died At Stop Light / Grinding Noise

2001 1.5 Accent. It has not been starting consistently for the last few weeks. Ive had to use the jump box on it a few times and that worked.

The other day (cold day!) it died at the stoplight after driving for about 20 mins. It made a grinding crunch sound from under the hood as it died. After several attempts on jump box it fired up and ran again for about 15 seconds and died and made sound again.

This repeated itself a few times before I got it towed home.

I removed alternator and it tested good (PASS) at two parts stores...testing 3 times each.

Battery has about 14 volts at the posts without having charged it after event.

What would cause the car to die and make the awful sound? And why would it appear to need a jump start?

I was thinking alternator but.....

Hyundai - Accent :: 2002 Auto Transmission - Downshifts With A Jerk / Thunk

2002 Hyundai Accent with automatic transmission. This problem happens only if I floor the gas gas on the highway (trying to pass somebody or get out of the way in a hurry) or if I apply too much gas after coasting around a sharp turn. My car will then downshift with a jerk and an audible THUNK!. Right now I just avoid those situations and it shifts through all its gears fine, it only happens when I cause a sudden downshift. Transmission fluid level and color fine.

Accent LC (2000-05) :: Auto Trans Went Out / No Reverse And The Only Forward Gear Is First

I've got a 2003 Accent and my automatic transmission went out, no reverse and the only forward gear is 1st. Was thinking of pulling it and swapping it for a used, but I have been reading on here the many, many automatic transmission problems of the accent and my next thought was to just rebuild it myself. But now I'm thinking more along the of a swap from auto to manual, as I don't want to have to rebuild a transmission that is only going to have to be rebuilt again anyway. As far as stuff like the clutch pedal, linkages, gear shifter, I can get those pretty easily. Does the Accent have a hydraulic clutch?

Accent LC (2000-05) :: 2001 GL Won't Turn Over / Buzzing Noise Coming From Beside Cold Air Intake

I have an 01 Accent GL 1.6L. It will not turn over. Battery, terminals, and wires are all new. Alternator is also good. There is a buzzing noise coming from beside the cold air intake. I'm not sure what part that is. The part that is buzzing is where the cam position sensor is connected to. It also has wires that run into the firewall.

Accent MC (2006-11) :: Auto Transmission Not Engaging At Idle Then Abruptly Chunking Into Gear

My wife has been using her mom's 07 Accent, the mom is 90 and hasn't been incapable of using it for a while now. I did an oil change (without paying much attention) I've never seen this type of car before. Oddly the oil level seemed outrageously over full and still dirty

Then upon driving it the automatic transmission was all wacky, not engaging at idle, then it abruptly chunking into gear...

So I check the transmission fluid level and it's not on the stick. Research here let me know SP-III is what I'd need. Then while surfing a youtube vid regarding this model's transmission it hit me in the face, I'd drained the automatic transmission fluid! Went to the Kia dealer got 3 quarts dumped it in there, drained the overfilled 5.5 quarts of old and new oil rectifying my mistake, which brings me to the reason for this post.

This 2007 car only has 24,300 miles on it and I mistook the automatic transmission fluid for outrageously dirty engine oil! I swear this stuff looks like it's fulla carbon black n burnt up. My question: is it normal for the trans-fluid to have such a degraded appearance in only 25,000 miles?

Accent LC (2000-05) :: Auto Trans Will Thud When Coming To A Quick Stop

I have an '05 accent with an auto trans. The car only has 25k on it with the original trans fluid. Every once in a while the trans will thud when coming to a quick stop. It actually doesn't even make a noise, but you can feel it going into presumably 1st gear. It only happens when I need to semi-quickly stop for a yellow light etc. right as I'm coming to a complete stop. Trans seems completely fine otherwise. Is this a normal thing? Just an older style/technology auto?

Accent LC (2000-05) :: Auto Shifting Hang Between 3rd And 4th Gear At Normal Driving Speed

My wifes 2001 Accent at slow speed seems to change into its gears ok. But when at normal driving speed, it seems to hang I believe between 3rd and 4th grar. If you let off the accelerator a little, it will change, kinda hard into gear.

Also, when decelerating, it seems to "surge" when going from 2nd to 1st and almost acts like it wants to die. this is an Automatic Transmission.

Things I have tried: replaced flex exhaust and reset a P0133 error code. Condition still exist after 100+ miles of driving. Tried cleaning MAP/MAF sensor, PCV valve. It will not showing any more codes or check engine light with this current condition. I am at a loss as where to go next for diagnostics. If I just had a code # to work off of....
