Allison Transmission is a leading manufacturer of commercial duty automatic transmissions and hybrid propulsion systems. Allison products are specified by over 250 vehicle manufacturers and are used in many market segments including bus, refuse, fire, construction, distribution, military and mining. From 2010 to 2016, there have been over 1,400 customer complaints to the National Highway Traffic Safety Administration (NHTSA) about transmission problems with Allisons on-highway products alone.
The most common complaint is that the transmission slips or jerks. Other problems include sudden or hard shifts, delayed engagement when shifting into gear, transmission overheating and loss of power.
Allison Transmission is a name synonymous with quality in the world of commercial trucking. However, even the best can have problems and that’s what we’re going to talk about today. Specifically, we’ll be looking at some of the more common Allison Transmission problems and discussing what you can do to mitigate them.
One of the most common issues faced by owners of Allison Transmissions is premature wear. This can be caused by a number of factors including poor maintenance, excessive idling, or even incorrect fluid levels. If you suspect your transmission is experiencing premature wear, it’s important to have it checked out by a qualified technician as soon as possible.
Another common issue is leaks. Now, there are a lot of different places that a transmission can leak from so it’s important to pay close attention to where any leaks are coming from. The most likely culprits are going to be the seals and gaskets which can deteriorate over time or become damaged due to improper installation.
Again, if you think you may have a leak it’s best to get it checked out sooner rather than later. Finally, we come to one of the more serious Allison Transmission problems: slippage. Slippage can occur for a variety of reasons but is most often caused by worn clutches or bands inside the transmission itself.
If left unchecked, slippage will eventually lead to complete failure of the transmission so if you think your truck might be slipping make sure to get it into a shop right away! These are just some of the more common Allison Transmission problems that truckers face but thankfully they’re all relatively easy to fix if caught early enough.
Are Allison Transmissions Reliable?
Yes, Allison transmissions are considered to be very reliable. In fact, they are so reliable that many manufacturers of heavy duty trucks use them in their vehicles. One reason for their reliability is that they are built with high quality materials.
Another reason is that they are designed to be durable and able to withstand a lot of wear and tear.
How Do I Know If My Allison Transmission is Going Out?
If you think your Allison transmission may be going out, there are a few things you can look for to be sure. First, check the transmission fluid level and quality. If the fluid is low or dirty, it could be a sign that the transmission is not working properly.
Also, listen for any unusual noises coming from the transmission while it is in use. If you hear grinding or whining, it could be a sign of trouble. Finally, pay attention to how the transmission shifts.
If it seems to slip or hesitate when shifting gears, this could also be an indication that something is wrong. If you notice any of these issues, it’s best to have the transmission checked by a professional as soon as possible to avoid further damage.
How Many Miles Do Allison Transmissions Last?
Assuming you are referring to the Allison 1000 transmission, they are built to last. With proper maintenance and care, they can easily last over 200,000 miles. There are many factors that will affect how long your particular transmission will last, such as driving habits, terrain, and maintenance schedule.
If you take good care of your Allison 1000 transmission, it will most likely outlast your vehicle. That being said, there are still some things that can go wrong and shorten its lifespan. The most common issue is with the torque converter.
If it starts to fail, it can cause a loss of power and eventually lead to transmission failure. Another potential issue is with the clutches. If they start to wear out, it can cause shifting problems and eventually lead to transmission failure.
Proper maintenance is key to preventing these issues from happening. If you keep your Allison 1000 transmission in good condition, it should last a very long time. Just be sure to do regular check-ups and follow the recommended maintenance schedule.
How Much Does a Rebuilt Allison Transmission Cost?
If you’re in need of a rebuilt Allison Transmission, you can expect to pay anywhere from $2,500 to $4,000. This price will depend on the severity of the damage, as well as the year, make and model of your vehicle. It’s also important to note that labor costs will be additional and can range from $500 to $1,000.

Allison 6 Speed Transmission Problems
The Allison 6 speed transmission is a popular choice for many drivers, but there are some common problems that can occur. Here are some of the most common Allison 6 speed transmission problems and how to fix them:
1. Slipping Gears: If you notice that your gears are slipping, it’s likely due to low transmission fluid levels.
Make sure to check your transmission fluid levels regularly and top off as needed. 2. Noisy Transmission: If your Allison 6 speed transmission is making strange noises, it could be due to a problem with the torque converter. You’ll need to have a professional take a look at your transmission to diagnose and repair the problem.
3. Hard Shifting: Hard shifting can be caused by several different issues, including low transmission fluid levels, worn out clutch plates, or dirty clutch fluid. Again, it’s best to have a professional inspect your transmission to determine the cause of the problem so it can be repaired properly.
There seems to be a widespread problem with Allison Transmissions in Chevy and GMC trucks. The problem is that the transmission will slip out of gear, especially when going from reverse to drive. This can be extremely dangerous, as it can cause the truck to lurch forward unexpectedly.
There have been numerous reports of this happening, and it appears that Allison is aware of the problem but has not yet issued a recall or service bulletin. In the meantime, owners of trucks with Allison Transmissions should exercise caution when shifting gears.
