i have a 1993 3/4 ton pickup 5.7 and it just started to shift rough it has to get up to 4000 rpm to shift from 1-2 and 2-3 someone told me to change the filter another person told me to check the vacume line i went under truck and found a vent tube out the side not sure what to do
View 1 RepliesI have a 2006 Chevy 2500HD with about 180000 miles. All of a sudden the transmission is shifting extremely hard at times. It doesn't shift this way all the time. What could be causing this problem? It doesn't have to be under hard acceleration either when it does shift hard. It sometimes is during hard accelerating and sometimes it is under very little acceleration, but as I said it doesn't do it every time. When it does shift hard, it seems to do it in all gears.
View 1 RepliesJust 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.
View 6 RepliesEvery 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?
View 2 RepliesMechanics say they don’t know what wrong… I had some transmission work done on my truck – mostly an leak and replacing the harness – and ever since then after it rains or if we have a heavy dew my truck does the following:
Driving from O to 49 miles an hour truck is fine, as soon as I hit 50 the truck starts surging and you can see the tachometer jumping from 2000 RPM to 2500 RPMs. I drive around 17 miles to work where my truck will sit for seven hours. On the way home the truck is fine. I find this to be more of a problem when the truck has sat for a day or two over the weekend without driving it. Sometimes the “check engine” light will come on, sometimes not.
I have taken it to two different places and neither one says they can find anything wrong with the truck. I have driven this truck for over 11 years and know it very well. There is something wrong, but what? 1993 Chevy Silverado 3500 Diesel....
I can smell transmission oil burning through my engine. Is it because my modulator is faulty, or do I even have one? Do I have a solenoid instead? How do I get to the part, whichever one it may be?

View 3 RepliesI have a 3/4 ton chevy silverado. It has 106,000 miles. I have not had the transmission fluid changed yet. I've read it is best to change fluid between 60,000 and 100,000 miles and to change this every 30,000 miles. I've also heard that if I have not had this changed prior to 60,000 miles that it is too late to change this now. Is this correct? Recently, I've noticed the transmission slips when shifting geers(this is automatic transmission). What do you recommend.
View 9 RepliesI drive a '93 Toyota T100 with a manual transmission. Up until recently things were going great but I've noticed it is damn near impossible to shift from reverse back into first gear when I'm pulling out of my driveway. I've also found that shifting from first gear to second has become more difficult as well though not impossible. However if I'm shifting to third, fourth, or fifth gears I don't have any problem whatsoever. I had the transmission redone about a year ago after the clutch gave out so I'm hoping its not that.
View 9 RepliesI bought a '93 F150 4x4 this past Sunday. It has the 5.8 and E4OD. Yesterday when I started it up and drove to the tire shop for some wheel balancing, it shifted VERY hard with each shift, so hard that it concerned me. I know very little about transmissions in general, and this one specifically, aside from it being electronically controlled.
This afternoon, I drove it again and it seemed to be shifting more "normally" without shifting anywhere nearly as hard as it did yesterday. What I should check first? I bought a filter kit and will change the filter/fluid (including torque converter) as soon as I'm able.
My 1993 Sundance with automatic transmission abruptly jammed. It won't go into park but will go into the other gears including reverse. Since the only way to stop and "park" the vehicle is to shift into neutral, the key is now permanently stuck in the ignition. What did I do or what happened?!!

View 2 RepliesFor the past several months, every now and then while driving the engine power will reduce and the Driver Information Center will display two messages: "Service Stabilitrak" and "Engine Power Reduced", and the ESC and Check Engine dashboard lights will come on. Shifting becomes rough especially between 1st and 2nd gears. After turning off the car for 10 minutes or so, the engine power will be restored and the ESC light goes out but the Check Engine Light remains lit. After a day or so the Check Engine light goes out. Otherwise the car runs normally. This happens at least once on every long trip where I am out on the highway - sometimes multiple times on a single road trip. It does not happen in short trips around home.
View 1 RepliesI have a 2007 Chevy Equinox with 104,500 mi. For the past 20,000 miles (2-1/2 yrs.) or so the transmission hesitates when shifting from 2nd to 3rd gear. When this happens, the engine revs and the wheels lose power for a second or two, and then the shift completes.It happens anywhere from once or twice a week, to once a month.It never produces a "Check Engine Light" nor a "Code" when scoped the same day.It is more of a nuisance, although doing it while pulling into traffic could cause a nasty safety issue.I have had it checked by independent mechanics and a local Chevy Dealership and nobody has an answer.
View 5 RepliesI have a 2002 Chevy S10 ZR2 4x4, the transmission will shift through 1st and 2nd gear up to 30mph then will not shift anymore. I have notice if you are easy on the gas you make get lucky to shift into 3rd, but the transmission downshifts to 2nd and only 30mph. I've tried shifting into 3rd manually, if the rpm is high it will not shift into 3rd but if they're low it will shift and if you press the accelerator just a little harder it will shift back to second and speed will drop to 30mph. I've changed transmission fluid and filter. The fluid was dark. I put DEX VI transmission fluid back in. Problem still exist.
I just have so much to explain and not sure how. I bought this truck from a person who bought this truck brand new in 2002. He was always kept the truck maintenance but he said he has never changed the transmission fluid. The truck has 276,000 miles but they are mostly highway miles from driving from NC to DC and back. I can assure you guys this truck hasn't been "dogged". I read one forum and someone said to changed the ignition switch wire harness. I'm not sure if that has anything to do with it, but I only seen one person say that and I'm not sure if it works.
2007 Chevy Impala3.5L 6-cyl Flex Fuel engine w/ 4 speed auto trans52,800 miles
Extreme driving conditions maintenance schedule kept.Transmission standard service done @ 32,800 miles which was 20k ago.
PROBLEM:
1) Twice in past three days, when shifting from reverse to drive the transmission has slipped, revving hard with rpms spiked above 3,000 for about 2 seconds before engaging the forward drive gear.
Normally I come to a complete stop of all reverse motion with foot fully on the brake pedal before shifting. Admittedly, I got sloppy the first time noted and still had very slight reverse motion when I shifted.
2) Several times late today, while driving uphill at approx 35 - 45 mph, when the car downshifted there was an extremely brief moment of transmission slippage with spiked rpms. It was so brief each time that at first I thought I'd imagined it until it happened again. Then it did it once on a level surface in a parking lot when having shifted from reverse to drive without problem and was gently accelerating the transmission again slipped for just the briefest moment when the normal automatic shift point was reached. So far, all incidences while driving have been so extremely brief that it was the merest hint of a hiccup.
3) When bringing the car to a complete stop, such as at a stoplight or when parking, as the transmission automatically shifts for the braking of speed, sometimes there is a minor but noticeable thunk sound seeming to come from underneath the car, I'd judge to be somewhere about under the level of the dashboard or slightly forward of that. Could that be from a worn or broken transmission mount? And, if so, could that be somehow causing the slippage problem?
4) This transmission has always, even since new, allowed more roll after being shifted into park, the engine shut off and my foot taken off the brake than any other car I have ever driven. If I forget to engage the parking brake quite tightly, the car will roll forward quite a few inches before the parking pawl holds it, even on the level. I've been told both by the dealership shop and the independent mechanic shop that there is no problem and that this particular engine/transmission combination tends to do this although my particular car seems to do so somewhat worse than average.
ACTIONS TAKEN SO FAR:
1) Have made an appointment to take the car into the mechanic.
2) Will check the transmission fluid level per instructions in the owner's manual tomorrow when I have daylight to see what the fluid level and color on the stick looks like.
NOTE:
1) I periodically check the transmission fluid level and it has never been low or discolored. The shop checked it for me, along with making sure everything else was road trip worthy, for an emergency 1,000 round trip in late November, just three months ago. No problems then.
2) No evidence on the garage floor of any leakage. Garage floor is dry.
QUESTIONS:
1) I presume the first step is for the mechanic to check the fluid level and examine for any leaks?
2) If the mechanic cannot duplicate the problem in a test drive, then what?
3) If the problem cannot be duplicated and no apparent cause found, I presume that the prudent course of action is to go ahead and have standard transmission maintenance done (i.e. drop the pan, check for debris, drain and replace with fresh fluid) then see if that halts the slippages?
4) Given that this car has already had failures of the power steering pump, water pump, and part of the wiring harness, and has a fuel pump starting to get noisy, despite aggressively maintaining all standard/preventive maintenance, that perhaps it is time to think of replacing this car, especially if there proves to be any truly major transmission problem found?
I'm having a ton of fun driving in Sport transmission mode. One thing I'm noticing though is pretty rough downshifting from 3-2-1 sometimes. Often I hear and feel a clunk.
So I'm wondering if the transmission may not be adapted to me yet, since I've only had the car for 5 weeks, or could I be looking at an issue. No lights or warnings on the dash.
Also wondering if there is a way to "reset" the learning algorithm of the transmission without the VAGCOM?
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.
View 2 RepliesI just bought a 2013 Barcelona Red Corolla S in Manual transmission. Already, I've noticed how rough the transmission is when I shift. But it's only roughy when I first step on the clutch. But if I keep the clutch pedal down, all the gears shift smoothly, until I release the clutch and press it down again, then the first shift is really rough. Especially REVERSE, when I shift into reverse, it's so rough that it shakes the car. There's no grind, just very rough. It sounds like someone cocked a shotgun. Everything is smooth when driving tho, only happens at full stop.
