The transmission in a modern truck is very complex. It needs to shift from mostly-automatics to almost entirely-automatics in just a few years, so it is important to know how to have an automatic transmission work properly.
General rules for transmissions include: never touch the shifter when it is in park or reverse; never put any pressure on the shift lever when it is in park or reverse; and never let go of the park or reverse buttons while the vehicle is moving.
These rules apply even if you have experience with a manual transmission! Most importantly, never dispute whether the transmission is working or what mode it is in because those symptoms can be different. If one of you notices something wrong, then the other one will know something has to be shifted into gear to fix it!
This article will talk about some common problems that may cause your automatic trans shift solenoid not to function correctly and/or turn off automatically when your vehicle is in park or reverse.

Soft shifts
When changing gears in an automatic vehicle, you may experience a soft shift. This can be problematic when chasing a car down the road or going straight and changing gears requires taking your foot off the pedal.
If this happens when you are driving, then it is probably time to change the transmission. A transmission has transfer cases that shift the vehicle. When dealing with a automatic transmission, there may be an issue with one of the transfer cases.
When looking at a automatic transmission, there may be two transfer cases that deal with rotation and distribution of torque. If one of these transfers cases does not work properly, then you will notice that the other one feels reluctant to rotate or distribute torque.
This reluctance can lead to harsh shifts and concerns about stability and protection.
Hard shifts
One of the most common problems associated with automatic transmissions is hard shift syndrome. This happens when the transmission cannot find a gear enough of the time and needs to shift again.
This can be problematic if you are running off a generator or have to maneuver in an emergency. A well tuned automatic transmission will not make a lot of noise as it shifts.
A well tuned automatic transmission will require you to press down on the shift lever for a brief amount of time before it moves and turns over. This allows it to reach its correct operating temperature and reset itself.
An easy way to check whether your truck has hard shift syndrome is by trying to move up or down in gear. If you can do this without difficulty, then your truck has soft shift syndrome and nothing else is wrong with it.
Jerks forward while driving
As mentioned before, automatic transmissions have a shift point where the car will move forward when you press the shift button.
This can be a little confusing if your truck does not have this feature. When it does, it can be jerky!
When it shifts, you almost feel like you are driving a manual transmission vehicle. It is kind of fun to watch as the other vehicles and your truck battle for top spot in your lane.
However, if your truck has no shifting function then do not worry! There are still ways to enjoy volvo truck automatic problemsthritisvierde! You just need to be more patient!
First, try turning the Transmission Ride Level Signal off with your car’s navigation system. Then, try moving around in your parking lot or on your field to see if anything changes the shifting movement of your truck.
Low speed downshift blaring noise
Bullet point! Die-hard truckers may remember a low speed downshift noise Heller-like sound that would occur when the transmission was in fourth or fifth gear? That’s the one that comes when you need to shift into first or second by holding the shift lever down for a short time.
If you don’t, then you’re looking at second or even third with no shift at all. It is very unnerving to do it on a highway, since there’s no protection against cars going around you.
It is extremely loud, too. While it does not hurt your ears, it can be annoying to have to hold the shift down for so long before it happens.
The problem that most people are having with their Volvos is the lack of confidence in those automatic transmissions when they don’t get enough tension on the shifting parts.
High speed downshift blaring noise
While driving at high speed, the truck will occasionally make a loud, abrupt shift. This sound is called high speed downshift.
High speed downshift happens when the gears are lowering the low gear and shifting to a higher gear. This occurs at higher speeds such as when driving along highway exit ramps or on inter-interstate highways.
When this happens, it can be quite nerve-wracking. You feel like you are falling out of control and your vehicle is going to take off without you doing anything to stop it. It is like a pre-death experience for your vehicle!
To prevent high speed downshift, keep an eye on your wheels as they come up from lower gear to make sure they aren’t coming off of the road. Also, try using a different mode button to see if that helps with the issue.
Transmission jerking while in neutral
A strange phenomenon occurs when a vehicle is in neutral. If the vehicle is moving, the transmission begins to rotate inthe clutch–and that’s not good!
It can happen occasionally, and for a person who is extremely precise with their vehicle controls, it can be noticeable.
Slow take off
vasquely timed or not, almost every detail of your car or truck is going to need attention at some point.
At around 500 to 600 miles per transmission fluid change, transmissions begin to need attention. This is their prime time to wear out as they must be flushed and stored in their entirety for this change.
Transmissions are designed to work with a certain amount of compression in the lubricant along the transmission housing. As the lubricant wears off, the transmission must be replaced. Aftermarket replacement transmissions do not have this amount of wear as they require new oil and gaskets when the old one is done with us.
However, at around this time, many trucks will be receiving their warranties renewed so it is important to get them in touch with a quick and complete check.
Late shifts
Late shifts is the biggest problem concerning the transmission in vans like the Volvo XC90. Late shifting can be done on a regular basis, it just depends on when!
When a truck automatic transmission is new, it does not have enough experience with shifting to understand when to shift into a lower gear. This can be frustrating at times, as you have to manually shift into another gear after you pass the one your destination is located on.
The best time to exchange your van’s transmission is when it has been in use for about a year and a half. If this happens recently, then you may have something wrong with your van’s transmission.
There are two main types of late shifting: rollback and pitchshift. Rollback happens when the truck shifts into a lower gear but then back up into an higher one. This happens because the automatic does not know how to move into another gear!
Pitchshift happens when the truck moves from one gear to another without changing any pressure on the accelerator or brakes. This usually happens when going over a bump or gradient.
