Transmission won t shift when cold

A car having transmission problems in cold weather is a very common issue. The main reason behind it is, that the low temperatures increase the viscosity of the transmission fluid and it doesn't flow smoothly in the system. This article talks about the various causes of this problem, how it affects the vehicle, and the methods that can be used to fix this issue.

Cold weather conditions often cause a lot of car problems starting from the ignition, to tires, to fuel lines, and eventually leading to a dead engine or dead battery in a car. Another problem worth mentioning is the thickening of the fluid oil.

It becomes dense to a major extent and creates a lot of friction in the starter motor. An automatic transmission system installed in a car is known to be a more reliable system these days. However, the occurrence of these problems is a very common issue, and in case you reside in an extremely cold country, troubleshooting is a primary option.

Would you like to write for us? Well, we're looking for good writers who want to spread the word. Get in touch with us and we'll talk This component makes it possible to create speed variations in the torque which is created by the engine. Without the transmission, a vehicle would be able to function only at a single speed. This system usually is available in two types: manual and automatic.

Speaking of common transmission problems in a vehicle, like broken gears and bands, fluids of a poor quality, and so on, automatic transmission problems in cold weather is very common. This condition is also called transmission slipping. In such cases, the system freezes and contracts, plus the fuel line fluid begins to leak from the seals resulting in a low line pressure. If the vehicle faces a low line pressure or inadequate fuel supply within the system, the gears would refuse to function correctly and that would cause slipping.

On the contrary, this slipping can also occur when the system gets too hot. Hence, to maintain a stable transmission system in a car, the pressure levels and the fluid levels have to regulate decently, without getting heated up or extra cold.

You have read how weather can affect the different components in a car and lead them to miserable conditions. So all you can do to avoid these problems is take quick action, like doing-it-yourself or turning your car into a service station.

I have a 99 GC and have been having problems with the transmission for a while but it is getting worse with the coming of winter. When the transmission is cold, it will not shift from 2nd to 3rd. I have changed the fluid 5 quarts and the filter but still no luck. I am now be quoted prices of to to fix if somthing major is wrong. Has anyone else experianced this? I have checked the fluid continously, and it is always good. In regards to the fronts seals being worn, any ideas on cost to replace?

I am kind of dumb lolbut would a automatic still have front clutch seals? The front clutch is the one right behind the front pump on this trans. The next clutch pack is called the rear clutch,it's behind the front clutch.

Hi J2, There are a couple of threads deeper into the Grand Cherokee section that also address this problem. If you haven't read them, I recommend that you do as they are helpful.

We have a 97 GC with V-8 and about 74k miles. This tranny was rebuilt under warranty at about 10K miles. A few weeks ago we also were having the shifting when cold problem. I mentioned the things I read in these threads. His suggestion was to do a chemical flush of the the tranny, torque converter and replace the filter. It took a heckuva lot of new fluid. We did what he suggested 3 weeks and 1 Hunting trip ago.

Have put on about miles and so far so good. I will keep you posted but so far we are pleased with the results! Mike :2cents:. Posted by j2arch - at PMI have a 99 GC and have been having problems with the transmission for a while but it is getting worse with the coming of winter.

Thanks In the transmission industry there is a symptom which is commonly called "Morning Sickness" mainly found in Ford's. Sounds funny, I know.

This is a problem that occurs when the neoprene seals synthetic rubber which is resistant to hydrocarbon oil and gas become hard and brittle. On this piston and in the housing itself there are several neoprene lip seals. This same concept is also found in the forward clutch housing or also known as the rear clutch housing. I prefer using the term forward and direct because your overdrive clutches are even more to the rear of the trans then what they call the rear clutches.

These neoprene lip seals sometimes become hard and brittle. Which as a result causes a loss of line preasure to the respective piston which apply the clutches. After the seals warm up they become soft and pliable again.

At which point they can move the travel of the piston to apply the clutches without loss of preasure the way they were originally designed to function.I put Lucas in the transmission because it was low on transmission fluid and was slipping in over drive then it stopped working at all after I put Lucas in it but when I first start it will go into gear and work fine until I get up the street then lose all gears how can I fix this. From what you describe it would appear that your vehicle may be experiencing some sort of potentially serious transmission issue.

If the transmission was having issues prior to mixing in the additive it may be possible that doing so exasperated the problems. Regardless of any additives, however, a transmission that does not shift properly can be caused by a few different things. A few common causes are low or dirty transmission fluid, or faulty shift solenoids. The transmission uses fluid pressure to shift the gears, and does so using electronic solenoids. If there is an issue with either of these the vehicle may experience problems shifting or transferring power to the wheels.

If these are not the problem then it could be possible that the transmission is having internal faults, perhaps a worn torque converter, or transmission gears, inside of the transmission. As issues like these can sometimes be difficult to diagnose, if you are unsure, I would recommend having a professional technician, such as one from YourMechanic, visit your location to diagnose what may be causing your issues.

Used Cars For Sale.There are some issues which need to be taken care of properly when using our cars in cold weather. It is a known fact that in cold temperatures, a car may consume more fuel to start up the engine in order to be fully operational as in warm conditions. In cold weather, a car engine is much more difficult to start because the oil used in it becomes thicker and requires more energy to get to its normal state.

The engine parts which are lubricated by the cold thicker fuel require significant energy in order to be activated. So, it seems quite simple to have transmission problems in cold weather. Usually, a higher energy requirement means that the engine will take more fuel to get its parts moving. The engine will definitely end up consuming a large amount of fuel to get the car warmed properly. But, experiencing a shifting in weather conditions is not a sign that the transmission has broken or that it has an immediate problem, it is an early sign that there will be a problem at some point.

What you should know further on is that there is a difference between the manual and automatic cars and the symptoms are different as well. Usually, manual cars will have trouble getting into the correct gear as a consequence of the cold weather. Not to mention they are more difficult to start when the weather gets colder. You should not ignore these symptoms even if they disappear once the weather begins to warm up as they might be an early wake-up call to take your car to a mechanic and check it up of some transmission problems.

The automatic transmission is the most complex mechanism and if you notice some warning signs that something is not working the way it should be in cold weather, the most important thing to do is to take your car to a specialist and have a transmission repair. What you should do when trying to use your car in a cold winter day is to check the engine light. The modern automobile computers are extremely sensitive and can detect a transmission slip or malfunction that usually is imperceptible to the driver.

But, the light will always come on to tell you that something is wrong somewhere. From here is quite easy to see that something is wrong and get your car to be checked out. Among some symptoms that you can notice, we should mention a shaking sensation, burning smell, delayed drive or leakage.

Previous Post Previous post: Audi A6.I have a Jeep Grand Cherokee Laredo with a two wheel, rear wheel drive transmission with 78, miles on it. Everything works well except that the automatic transmission sticks in cold weather 50 degrees or colder. I have to drive the car 2 or 3 miles before it will shift into a higher gear. It gets really bad in 30 degree weather or cooler. Any help is appreciated. I had the transmission fluid changed.

Try a can of Trans-X or Seafoam and see what happens. I doubt very highly that you are looking at a valve body issue. With age, these seals harden and allow ATF to pass by them instead of retaining the fluid behind the piston.

As the trans warms up, the seals soften and will seal. This is why the trans operates well when warm. Tell me some more information. Do you have problems engaging reverse?? Where is the shifting problem ocurring?? Is it the shift, the shift or the shift or all of them??

You can pour a can of Berrymans Chemtool in the trans, this will help soften the seals when the trans is cold. With the age of the trans you might want to let it warm up a minute or two in the colder weather. Since this transmission will not circulate the ATF while the trans is in Park, I would set my parking brake and allow the trans to warm up in Neutral for a minute or two prior to driving.

This will allow the fluid to start to warm up and also charge the converter with ATF. If I keep hitting the gas, the RPMs go high. Can you replace the rubber clutch piston seals? To replace the piston seals you have to remove, disassemble, inspect, and reassemble the transmission.

Usually at this time a complete rebuild is done with replacement of friction components, seals, seal rings, gaskets, and worn hard parts. When was the last time the transmission fluid was changed?

These transmissions are rather finicky about the fluid. There are NO other fluids that are compatible with this transmission. How is the transmission cooler controlled on this car? If it is controlled and is overcooling that could contribute to the problem.

This is an inherent problem with Jeep trans…esp. I have same issue with a 96 Grand Cher. Sounds to me like Jeep has a major issue they do not want to face. Another thought. Which fluid type did you use when it was changed? Hope this helps some.

Unlikely, but make sure the transmission fluid level is not too high. Hi guys. Thanks for the advice with my car. Thanks for all of your help.Now I do not know if it is a coincidence, but I also have a ford ranger 2wd and changed the plugs and wires in it also, and it does almost the same thing, will not shift into drive, just sits there.

Just seems kinda coincidental that it is happening to both my rangers now! Andrew answered 11 years ago. How long does it take for it to finally get going? I don't know how plug wires would cause this, but I am not an expert. Deven answered 11 years ago. Possible the fluid may not be up to temp or they could possibly both be low on fluid. But i believe the plugs and wires would have nothing to do with the trans.

Since you worked on this yourself doublecheck all wire connections in the area that you might have bumped. It is easy to loosen one without realizing it. Double check fluid levellow level will cause delayed engagement into gear.

Automatic Transmission doesnt want to shift when cold??

Also double check you didn't knock a wire connector loose when working on the spark plugs and wires. Mkz answered 6 years ago. I tend to agree with the thought you disconnected something. Perhaps go back though each of the steps you performed when changing the plugs wires. I think maybe command module in tranny.

MrSmoke answered 5 years ago. I also tend to agree with the disconnect suspicion. The first 3 times I responded to a check engine light on 2 different cars, it was disconnected O2 sensor after routine work.

Can anyone suggest which connectors to look at? Your tranny problems are vacuum related or internal in the transmission.
