Gmc - Sierra :: 2012 - Transmission Shifting Sometimes Not Smooth In Lower Gears
Nov 21, 2013
I have a 2012 Sierra 1500 SLE with a 5.3 liter engine, 6 speed transmission and about 7700 miles. I have noticed that at times the truck does not seem to be performing efficiently and will not seem as smooth and transmission shifting is sometimes not so smooth in the lower gears. I have noticed that when I let the truck warm up for about a minute before putting it in gear, that all seems to go much more smoothly, but if I crank up cold and take off right away, then it tends to run not as smooth. I have even heard a slight "slap" type noise that I think is the transmission shifting when slowing down to make a turn at about 15-20 MPH. When I go to accelerate after the turn, it will sometimes slap as if it is hunting for the right gear. Obviously, I now let it warm up for a minute before I drive it. I have not talked to the dealer, but I probably will when I take it in for its 10K checkup.

Lately I have noticed that the transmission is not shifting smoothly in the lower gears. I have 114K on there. Spoke to my service manager and he mentioned that it may need calibration. Doesn't sound right after all the miles?

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.

I have been reading some topics with people having issues with their Camry transmissions and torque converters. I have 15000 miles now and I'm noticing not as smooth shifts anymore from 1st to 3rd gear. It also jerks a little when you suddenly step back on the gas.

When I start the car for the first time of the day, the shifting is not as smooth as when the engine is hot. Is this normal ? When I checked the trans fluid, it was between 25 and 75...(the second little mark on the dipstick) but I just drove about 5min so maybe the engine wasn't warm enough..

I have a 4l60e transmission that was rebuilt less than 500 miles ago, I was driving on the highway when all gears were lost. There is clicking in the front part of transmission. Can I just replace pump? Fluid is clean no pieces in pan, are cluthes still good?

I own a Camry SE 2012. Like a title above, driving with the ECO button on? I used to turn it on all the time, however, I've noticed something strange on my car recently. The transmission doesn't get smooth! I mean with the 6-speed auto transmission, it is supposed to change speed smoothly from 1 to 2, 2 to 3, respectively. It's like when I change from 1 to 2, the transmission is smooth enough, however, when I get to higher, it doesn't get smooth. I'm not sure if I turned the ECO drive off and it would get better or I just feel it so. My first thought was about the engine oil was not lubricated and out of date but I did maintained a week ago. It still happens on my car, but less than before.

New to the R, and recently the transmission seems to be making some noise throughout lower gears at low speeds, when the clutch is engaged the noise goes away, I figured it was the throwout bearing, but now my transmission now refuses to let me into 2nd gear and also reverse.
I changed the transmission fluid hoping it would eliminate the noise a bit, and saw very small metal shavings in the old fluid. I'm now worried I have a serious transmission issue... Are these signs of major transmission issues or should I be checking linkage? Any common transmission problems with the R I might be experiencing?

2015 Outlook 2.5 CVT - Regardless of engine temp/or oil temp, transmission will stay in low gears (relative - its a CVT) such that the car is always doing approx. 2100 RPMs. When it occurs, 35mph is 2100 RPMs; when problem is not present, same speed would be approx 1200 RPMs. Same for higher speed. 45mph would be 2100 verses approx 1400rpm. Gear indicator does indicate a '4' or '5' when it would normally be '6'.
Outside temps in excess of 30 degress - no evidence of problem. Below 30, may or may not happen. No check engine light and it does affect MPG significantly.

My friend has tortured my R32 which he was supposed to buy. I had the motor replaced while i was gone as he blew it , again , dumb. I have been driving it and it has a terrible whine in the tranny I brought it to my mechanic and we took a sample to find metal shaving in my tranny.
He says the tranny is gone but I am lost on how it shifts perfect except the whine. It does this louder in the lower gears and has a slight knock at idle and disappears when I press the clutch in.
I bought a used tranny already to put in. I also if this is the case and the tranny needs replacing I was told to also do the clutch , should I go stock to save money or go with a different clutch and possibly a LW Flywheel , is it really a drastic power difference?

This is an early 99 f250 powerstroke 6spd manual 4wd, is it common or normal to hear a lot of transmission rattle at low rpm especially in lower gears under a load. Starting off from a dead stop it sounds awful until about 1500 rpm where it clears up (or load is reduced). I'm hoping it's just the power pulses going through splined shafts, gears, etc.
210k on the truck, just changed every fluid in it.
I've been a honda owner and mechanic for all of my driving years where shifting at 8500 rpm is common and now I'm having a hard time learning what this thing likes, rpm ranges to avoid, ect; even shifting I find difficult. At least you can heel toe with the pedal arrangement...

My friend told me the other day her car was in overdrive (hwy driving) and suddenly, it shifted to a lower gear. It seems no one knows why. She does have an extended warranty, but the garage might charge her $300 to open it up to see what is wrong. Another friend suggested a clogged filter. Another one, a sensor.

My friend has a 2007 accent with a manual transmission they said that they were driving and the transmission stopped shifting gears. The clutch pedal still has pressure so I don't think it is a master or slave cylinder issue. They freaked out and turned off the car and now the car will not start up again. Have any of you experienced anything like this before or know on this car where to start looking? I think the issue with not being able to switch gears could be a pressure plate issue but this would not cause the car not to start.

I have a 2002 Saturn SL2 (automatic). A few days ago it abruptly started thumping pretty heavily when shifting gears, especially going into reverse and 4th (or possibly 5th) gear. A couple mechanics told me the transmission is going, and that it would need to be replaced (but it would cost more than the car is worth. One said that we could try replacing the computer that controls the transmission, but it would cost ~$300, and might not do any good. Another said to try Lucas Transmission Fix. I've seen mixed reviews of it online, so I'm wary. Is it a good product, or does it just briefly mask the problem? Also, I looked under the hood, and cannot tell where I would even put it.

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.

Every so often while driving in the city my car starts shifting rough between 1st-2en and 2en-3rd gears. If I stop; turn off the engine and then restart it stops. The car has 107,000 mi. and the fluid has always been changed as recomended. Do I have a shift selonoid going out somewhere?

A few weeks ago, my transmission (automatic) started rumbling while shifting from 3rd to 4th and 4th to 5th gear. Shakes the whole car, like you're driving over a rumble strip. Only when the engine is hot. I read online that I should get my transmission flushed and replace the fluid, but should I be expecting the thing to go or is this a normal hiccup for the Santa Fe?

My 2000 Hyundai Accent, and it has started shifting gears when not traveling at the right speeds to do so.
I'll try to describe it the best I can, When driving I will be going whatever speed limit and all of the sudden it will make a winding noise (like when jumping on highway and pressing hard on gas peddle) and the RPMs will stall. It is like when shifting up, the car drives as normal but then it will shift down and pulls back (making a winding sound)
I am not sure what to do, I was told it seems like it may be the transmission is shot(I had the fluid flushed previously) and that it could cost over $1000 to get it replaced.

I have a 1991 bronco with a 351w and the e4od trans.. The transmission is shifting late and hard and sometimes when i let off of the gas to slow down it shifts between gears up and down by itself... The only lights on the dash that are on is the Rear Anti-lock brake light and the speedometer is not working either.. Where to start the trouble shooting to fix it?

I am coming from a 2001 Acura CL-S which is a 5 speed automatic, and that car wouldnt' change gears that quickly. I understand cars today change gears frequently to be in the best gear for fuel efficiency?
But I feel like my ES350 changes gears so much, even at the slightest speed change. Is this normal -perhaps it's because I haven't driven a new car since my 2001, 12 years ago! Even the slightest press on the pedal will downshift the car and into the lower gear, even on ECO setting. On my Acura, pressing lightly on the accel pedal didn't result in a lower gear, as I know the engine had more than enough torque.
I also love reliability, and this makes me think the transmission would have a shorter life span with all the shifting. I still haven't asked my dealer about how often to do tranny fluid changes (which I know is a different thread altogether about discussions about "lifetime" fluid).
