When approaching a red light, if I take my foot off the gas to coast, it feels as if the transmission 'downshifts' at around 30mph. I can't actually feel the transmission shifting but there is a definite slowdown in speed, not just a gradual slowdown. Is this normal? I ask as doing the same in the '04 RX it does not do this.
View 5 RepliesI have 2010 Camry Le 2.5l with 39600 miles on it. Bought used from my uncle. The car is pretty good but I don't like the nature of new 6 speed transmission. Its always downshifting and I can feel the drag feels like car is braking by it self. Is this transmission designed to do that? In my previous thread I post the same issue and got reply that I will get used to it but I already driven this car almost 2 months but I am not used to that drag/pull back feeling when ever I take my foot off the gas pedal. Is there any solution for this drag/pull feel?
View 8 RepliesUpshifting is fine, downshifting gives me a big thud. Bigger from 3rd-2nd smaller 2nd-1st (I think).
2006 GS430. 120k or so miles.
Dealership replaced solenoid #2, but now say I need a whole new transmission.
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.
View 6 RepliesI have a 2009 that seems to have issues in the lower gears, I think that I have a transmission issue.
When I'm coming to a stop, I feel the transmission downshifting from about gear 3. It's not wildly jerky or abrasive, but it's not smooth either (or I wouldn't feel it). When it downshifts, after it engages (or torques down for lack of a better term) it feels as if it releases a bit, which makes me have to compensate with harder braking (again, not saying I am slamming on the brakes, but I have to brake harder so it doesn't feel like I am now going to coast into the car in front of me). It doesn't feel like the transmission is going to take off on its own, but it definitely feels like it has a certain threshold it wants to stay above.
In the loaner I have (RX), when coming to a stop the best way I can describe it is it feels like the transmission has completely disengaged and I feel NO transmission downshifting at all. The only way I get this type of braking in my LS is if I throw it into Neutral and take the transmission out of the loop. On the way to the dealership this morning to drop it off for other issues, I was at a stop light and went to accelerate and it felt as if it skipped a gear because I was stalled for a second (acceleration wise, not that the engine turned off) before it took off as it should. Also my acceleration seems to be a little hesitant when starting off .
Had problem with downshifting and up shifting quickly on its own and then engine light came on. 24,400 mi. Code P0713 Trans Temp Sensor "A" Circuit Input. They replaced it in a few hours and we will see how it goes. Had also had a problem of acceleration by its self when we first bought it and the gas mileage not being to par. Of course they said they haven't heard of that and they did an update/flash and haven't had that problem again, also had a broke front axle.
View 4 RepliesI have a 2011 Hyundai Elantra GLS... Few months back I refueled my tank with degraded fuel (of course i did not know about it and some refueling stations in our country mix oils) and the problems started to arise with my car.. initially it all started with jerks and cracking sounds from the engine.. I then took it to the dealership and cleaned everything except the injectors but the jerking and cracking problem was solved.. but it still had a pickup problem.. whenever i tried to accelerate from 40km/h to above, the transmission seems to give a jolt make a clicking sound when downshifting.. and the acceleration compared to before has degraded.. I took it to the dealership again and their answer was drive it for 300 km more everything will b fine.. but i have driven the car for 1000 km more but the problem is not solving.. I don't know.. my warranty period is over.. in our country they only provide for 12000 km or 1 yr warranty.. now i have checked online and it seems Elantra transmission has bugged a lot of ppl..
View 19 RepliesSo I just purchased my new-to-me, CPO 2010 RX 350 two weeks ago. It had 81,750 miles when I purchased it, and it now has about 83,000 miles. I just came back from a weekend vacation, having driving about 500 miles total. This morning when I turned on the car, I noticed a message saying "Check AWD System," the check engine light was on, the general warning light was on, and the traction control light was on. As I was driving, I realized that the car wasn't downshifting properly. I didn't drive faster than 40 mph on my morning commute. When the car did downshift, it was a hard, jerky shift.
I did some reading on the forum, and many people suggested all the warning lights could be fixed by taking off and retightening the gas cap (due to the vehicle not reading the emissions properly or something?). I also read that topping off and overfilling the gas tank can be cause for the warning lights to go on. I did fill up once on my way home from my vacation, and haven't filled up since.
Anyways, I just now tried to adjust the gas cap and then restart the car, but the warning lights are still on. What I should do or if I should drive it a bit to let the emissions build up again? My problem is is that I live about 6 hours from a Lexus dealership, so I'm trying to figure out if I can resolve this on my own or what I should tell a mechanic specifically if I need to take it in.
VW replaced my entire transmission and it still jerks into gear when downshifting to a stop or hitting the gas hard while coasting!
Also, I swear there is now binding while turning a la moteur stepper. New tranny. New rear drive shaft. Allegedly new transfer case (I cannot confirm this though). New new new programming. And still the darned thing vibrates by butt with a downshift that a Bettle with 300,000 miles on the clock would not dare make.
Any reference to the operation of the transmission and the sequencing of the various clutches and other coupling devices with respect to gear selection and engine conditions?
I've been driving my wife's sonata to work this week and notice as I start to slow down at around 20MPH the car almost surges a little bit. Maybe I am not diagnosing it correctly but it's almost like it's downshifting rough.

View 7 RepliesI took my Phaeton in for a transmission noise and they are saying it's "normal" for V8 Touaregs and Phaetons to have this noise on downshifting under acceleration from 4th to third at around 40 MPH. Yes?

View 14 RepliesMy freshly rebuilt C6 with Transgo shift kit and Hughes 2500 stall converter won't downshift until I'm nearly at a dead stop. My Cruisomatic did the same thing in stock form. I roll up to an intersection and the light is green. I slow way down to negotiate the turn. I then throttle when headed straight and the tranny is still in Drive. It does the same thing when slowing way down for speed bumps. Could the shift kit or stall converter affect downshifts?
View 10 RepliesHave an unfortunate circumstance. '03 Camry XLE 4cyl with 188k on it and the trans just went crazy. Was on the interstate and it started downshifting. Wouldn't stay up in the gear it was before and eventually wouldn't go out of 1st or 2nd gear.
Haven't had shifting issues in the past and trans fluid has been changed regularly at no more than 30k mile intervals.
Worst part is that this was on the way to vacation, so the car was towed to Ft. Walton Toyota. They are saying the trans is slipping and it needs a rebuild. Seems very odd to me that the issue would come on this fast with no earlier signs. A valve cover gasket was replaced a couple weeks ago, but I don't see how that could be the cause.
Sot he automatic transmission has never downshifted correctly for me in my "01 Hyundai Accent 1.6. I am on my second tranny, but they both never downshifted properly. For it to do so, you have to come to a complete stop for it to get back to first gear. If not it kind of bangs into first. Either that or it will dog out in third once you hit the gas, but will go into first. With my first transmission, I replaced the fluid and filter and it still did it. This second transmission has about 60k miles on it with new fluid/filter and does it.
View 4 RepliesMy daughter has a 2010 Sonata with a 4 cylinder and an automatic transmission. She is pretty frustrated with an intermittent problem. Every once in awhile, especially if the engine is cold, the car jerks while slowing down. She believes it is the transmission when it down shifts. I have driven the car and have not been able to duplicate the problem myself. The dealer recently changed the mapping for the transmission in hopes that would work but it hasn't. The dealer hasn't been able to duplicate the condition either.
View 52 RepliesI have a 77 F250 4X4, 400, C6. Upshifts and downshifts are working normally, except under light load and minimal throttle the tranny downshifts to 2nd at any speed under 40 mph. I've never had an automatic do this before. I checked the kickdown linkage is pulled up so it's doesn't seem to be in kickdown position always, no vacuum leaks to the modulator. I confess to be more of a manual trans guy so my knowledge is autos is limited.
View 2 RepliesWhen I am going into or downshifting to second gear in my GLI it makes a thud sound after I let out the clutch. It doesn't always happen and it does it if I just throw it down and if I don't have a perfect rev match. It just started a few days ago.
View 11 RepliesThe notorious 3.6 high idle has haunted me for over a year now. When it first started happening, I thought it was a temporary thing. It has been happening for a year now and the stealership has not been able to diagnose it. It has started happening more frequently now, no matter the weather. The idle overall is just rough. I place the car in neutral sometimes at a red light because the vibration and idel is so rough. The transmission is sluggish, and as i come to a stop sometimes, i can feel the rough downshifts it makes from gear to gear. And just today, after I picked up the car from the dealership from a failed diagnosis of the high rev problem, my parking sensors stopped working. When the system turns on(car in Reverse), there is a steady beep even while there is nothing behind me. Even as the car is moving(below 10mph) the car makes three beeps, every five seconds or so. I do not know what to do. I have a feeling that even if I take it to a different stealership, I will get the same results.
