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.
View 3 RepliesI have a 2003 F250 with a 5.4L V8 automatic transmission with 64,000 miles. The truck runs and drives well, but occasionally while driving, it acts like it shifts into a higher gear, slips a bit, then downshifts and runs fine. The duration of this "acting up" is about 1-2sec. It seems to do it when going up a slight grade at cruising speed about 40-50mph. (Not towing when it does it) It doesn't do it all the time. I'm planning to change the filter and fluid but am doubtful that will work. The fluid color is nice bright pink and does not smell unusual.
View 1 RepliesSo 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.
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.
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.
View 1 RepliesLast 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.
2002 CAvalier 2.2 automatic with 123'000 miles. I was asked to look at this car for a slipping trans problem.
I drove the car about 3 miles and in 1st and Reverse it feels normal, even on a steep hill, but once it shifts into a higher gear the trans slips and you can go only about 15mph.It is shifting, because if you move the shifter into a lower gear while traveling....you can feel it downshift.
There is a code of P0502 Vehicle speed sensor. and there is no Trans fluid visible thru the filler cap on the trans top.
Previously someone else worked on this car for the slipping trans....changed some sensors....but couldn't fix the problem. The owners don't know what parts he replaced. He works for a Tire outfit and I've known him to lean towards used parts a lot.The previous mechanic convinced them that it needs a new Cluster. I presume he means instrument cluster.
I have a feeling that he just threw parts at it hoping that something would stick.
I presume that he replaced the VSS, and it didn't cure the problem.Come to think of it....the code could be from before the other persons work. I should have cleared the code and test drove it again.
I'm looking at dropping the pan, replacing the filter, refill the fluid, and replace the VSS
My questions: Could a instrument cluster have anything to do with the shifting problem.
Is the level of trans fluid supposed to be above the ledge under the filler cap, or is there a "full level" plug in the side of the trans. If he replaced the VSS with a new one....and the fluid level is good....whats my next step.
My Subaru want to stall when it shifts from a higher to a lower gear when driving up a grade/hill. Also does the same thing when pulling out from a stop sign or traffic light. You need to pump the accelerator to get it going.
View 1 RepliesWhile driving my 97 Saturn SW2, the car couldn't shift into a higher gear (out of 2nd). while pushing on the gas, the RPM's would go higher but not shift. Also, the 'Service Engine' light came on. I don't have a code reader. Luckily I was close to home. When it parked it, I noticed a leak under the car, in the front section of the engine. I've also noticed that the past few days when putting the vehicle into reverse, it lurches pretty hard when it catches (as in, it jerks the car back suddenly). What could be the problem(s)? Should I drive this to the mechanic or have it towed?
View 7 RepliesMy 2006 Elantra (54,000 miles) shifts really, really hard when it's not cold and passes through the 35 mph range -- hard enough to make you glad you've got your seatbelt on. I've taken it to my regular mechanic and now it's in an automatic transmission shop.
My mechanic changed the fluid (twice), and took it through a "learning sequence". The fluid didn't look that bad and he reported that there were no codes to work with. He thinks I'm going to have to get a new transmission.
The AT shop has confirmed that there are no codes to work with and that the problem begins at 143 degrees. They tell me that the transmission is shifting into a higher gear without releasing the lower gear. They tried replacing a couple of solenoids, but that yielded no change in behavior. Now, they're telling me they "think" I need a new computer. I'm just afraid the trial & error approach is going to cost me a boat-load.
While driving in either D or S mode, the transmission jerks in 3rd gear changing into 4th and then its fine. but it always happens in 3rd. The jerks are very very quick.
My car is 4.2L 2004 V8 (6 speed) and it has 30,000 miles on it.
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?
So my trans clicks and jerks every time it downshifts into 2nd but that is the only time it does it. When i down shift using the tip shift it doesn't do anything and it all feels normal. What it could be being that it is just when it downshifts into second.
My car is a 2001 v6 4motion.
On my 2003 Chevy Impala with 127,000 miles the car jerks like someone has hit you in the rear end, it usually happens from first to second and is becoming more frequent. A recent transmission service had no effect
View 2 RepliesI have a 2002 Hyundai Sonata (automatic transmission) that has recently been "jumping" when the car shifts between 2nd and 3rd. This happens only after the engine is "warm", and does not happen in any other gears or when I downshift.
View 1 RepliesThere 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.
Have a 2002 avalanche Z71. Transmission was rebuilt 33k ago. It currently shifts a little hard going from 1 to 2nd. Real problem shows up between 40 mph and 50 mph. It suddenly shifts into overdrive which drops the engine rpm waaay down and starts lugging the engine.
Took it back to the guys who did the rebuild. They drove it around and noticed that the computer reported no codes. They claimed it was the TPS and said to replace it. I did. Problem is still there.
Took it to a highly trusted mechanic. They said they think the valve body needs replacing but they don't do transmissions. The guy they recommend drove it around and he thinks it is the torque converter.
I am wondering what causes the computer to decide when it is time to shift into overdrive and I am wondering if there is some sensor that has gone whacko and needs to be replaced instead of starting to tear the transmission apart.
In the last month or so, my Phaeton started to 'kick - jump' when it shifts between 2nd and 3rd gears. It mostly happens during downshifting below 10mph, close to stopping (the car is hot/cold; sport/regular mode - no difference) It sometimes does it during up-shifting. What may have been causing it?
I took the car for service last week, after talking VW techs service manager suggested to replace the 'Mechatronics (?)' in the transmission and have already ordered the part. I am wondering if this is a major work, and I am a bit worried if they can put my car together the way it is.
130,000 miles transmission shifts hard in every gear sometimes other times it is completely fine. Thought about servicing it with new fluid, filter, flush but have heard that this could cause problems since so many miles...
View 19 RepliesMy transmission has started slipping as car shifts into 2 and sometimes 3rd gear. It races and is not engaged, so there is no power for the few seconds (sometimes longer) when this happens. Car has about 216,000 miles - and it's time to also replace tires. As I look at the estimated bill, I'm having to decide if it's still a good investment to do the work on the car. I love the car and there is no rust or other problems.
