At DeLand Transmissions, we rebuild transmissions in-house. We primarily specialize in modern automatic truck transmissions, and back all stock vehicles with a 2YR/Unlimited mile warranty.
Please note that at this time, we are unable to complete repairs on certain vehicles. This includes, but is not limited to: manual transmissions, continuously varible transmissions (CVTs) , and imports.
In most cases, there are better options than stock/OEM parts. If you need a transmission rebuild and have a modified vehicle or heavy-duty application, you may want to–or need to– consider upgrading your stock internals. Depending on the application and the specific transmission, options may vary, so please ask our staff about what upgrades are available and/or necessary to fit your needs.
For all non-stock or performance vehicle applications, we spec our builds to suite your needs. Whether you’re wanting track performance, towing capability, or a mixture of both, we offer performance transmission builds for many modern automatic units.
Below is a list of the transmission builds we offer:
Ford’s RWD half-ton transmissions are a fairly robust transmission, but not without some glaring problems. Defective electronics are common, as are valve body issues. These issues often get misdiagnosed, leading many shops to fix symptoms instead of causes. This leads to comebacks and repeat issues. It is crucial to understand how to address the root cause of issues in this unit(hint hint: we know how).
The 6L80/6L90 transmission replaced the 4L60 and 4L80 in GM rear wheel drives. They have a very high fail rate, due to several design flaws. Fortunately, the aftermarket addresses these issues very effectively. Additionally, many upgrades are available; through these upgrades and tuning, these units are highly reliable once built properly. For this reason, it is our favorite and most common transmission to rebuild. Most important to building these units is understanding how to diagnose and address shudder/vibration issues both in and outside of the trans.
Along with many variations of this unit, the 10-speeds found in most Ford and GM units are extremely similar. Both factory and aftermarket support are available for these units, which makes service and rebuild very efficient. Furthermore, available updates to common failpoints are making these units very reliable once rebuilt.
Found in 2008-up Cummins trucks, these transmissions have to hold up to a lot of power. Stock rebuilds are NOT available! Many upgrades are necessary and are always customized to your truck. For this reason, many transmission rebuilders stay away from these units. However, these have been hugely successful units to build for us, with an extremely low repeat failure-rate. Please have any tuning/programming information available.
These heavy-duty Ford units both have many upgrades available, usually for heavy duty applications. They can be built for high hp/street performance and towing with very high success. Even stock, they hold up decently well to added power and towing. But as the units get older, repeat failure is common if the building shop does not address certain issues properly(yeah, we got this). Make sure to get to the right shop.
