If you use your truck for towing, the transmission upgrades we are showcasing are a great way to ensure your transmission stays together and delivers the reliability you need.

Choosing The Right Transmission Upgrades

When it comes to choosing transmission upgrades for towing, there are several factors to consider.  For instance, the type of vehicle you are towing with will determine the type of transmission upgrade you need. Trucks, SUVs, and vans all have different requirements when it comes to towing, and you need to choose an upgrade that is suitable for your vehicle. Also, the weight you are towing will also determine the type of transmission upgrade you need. One aspect you might not think plays a role in parts selection is the driving conditions you will encounter when towing. For example, if you will be towing in hilly or mountainous terrain, you will need an upgrade that can handle the demands of steep inclines and descents. Finally, your budget will also be a factor in choosing a transmission upgrade.

Transmission Upgrades For Towing

If you plan to do a lot of towing, RevMax has a few tips that can help your transmission live a long and healthy life. For starters, check your transmission fluid regularly. Towing puts extra strain on your transmission, so it’s important to keep an eye on your fluid levels and quality. Regularly checking and changing your transmission fluid can help prevent overheating and damage.

Using the right towing equipment is crucial. Make sure you have the appropriate hitch, tow bar, and safety chains for your load. Double-check that everything is secure before hitting the road. Also, avoid aggressive driving. Sudden stops, starts, and turns can put extra strain on your transmission and increase the risk of accidents. Drive cautiously and give yourself plenty of time to brake and turn.

You should also consider upgrading your cooling system. Towing generates a lot of heat, which can damage your transmission. Upgrading your cooling system with an auxiliary cooler or larger radiator can help keep your transmission cool and prevent overheating it’s no secret how heat can affect a transmission’s lifespan, and you can learn more about that by clicking here.

Converting Torque Into Movement

Towing heavy loads can put a significant strain on your vehicle, so it’s essential to take care of it. One critical component of any towing vehicle is the torque converter. RevMax offers high-quality torque converters that are specifically designed for towing applications. Using a high-quality torque converter can improve low-end torque and towing capacity, making it easier to tow heavy loads.

Transmission upgrades

RevMax torque converters come in different stages and offer several stall speeds. For instance, the Stage-4 converter is designed for those with mildly modified engines who don’t tow heavy weights. The Stage-5 triple-disc billet converters are designed for those who have heavily modified engines or for those that tow heavy weights. RevMax has redesigned the lockup clutch piston to be able to accommodate a piston damper. This upgraded billet piston and damper allows the clutch to apply more smoothly, which in turn puts much less strain on the input shaft.  Revmax Stage-5 converters have no horsepower or torque limitations. In fact, they dare you to try and break it.

In addition to using the right torque converter, it’s essential to choose the right gear ratio for your vehicle’s differential. Vehicles with lower gear ratios are better for towing, as they provide more low-end torque. RevMax offers a range of different gear ratios for transmission upgrades, which can be tailored to your specific towing needs.

Regular transmission maintenance is also critical when towing. Dirty or contaminated fluid can cause significant damage to your transmission, which can be costly to repair. RevMax recommends changing your transmission fluid every 30,000 miles when towing.

Our trucks are designed to tow and haul, and the listed transmission upgrades are a great way to ensure they do that for a long time.

It is no secret that it’s essential to avoid overloading your vehicle when towing. Overloading can be dangerous and can cause significant damage to your transmission. Make sure you know the weight of your trailer and cargo and ensure that it doesn’t exceed your vehicle’s towing capacity.

Valving Your Transmission Upgrades

Owners of Ram trucks with a 68RFE transmission know all too well how beneficial a valvebody upgrade can be, but you Ford and GM guys can also realize how much a valvebody swap can do to improve the performance of your truck’s transmission.

Allison 1000 Signature Series

The Revmax-built Allison 1000 Signature Series performance automatic transmission boasts a remarkable capacity to hold up to 1500 horsepower. Achieving that capacity requires upgrading the transmission’s shafts — which many rebuilders do not do. RevMax does not leave these optional upgraded parts out during the production of their units. To ensure optimal performance, RevMax recommends upgrading the input shaft for customers who tow with more than 850 horsepower. If producing more than 1,000 horsepower the output shaft should also be upgraded. If you are well above 1,000 horsepower, it would be time to consider upgrading the intermediate shaft.

Revmax says their units are equipped with the best internal parts available and have invested over $150,000 in valvebody testing equipment to provide customers with the most high-performing and rigorously tested valvebody on the market. Each valvebody is custom-configured to the customer’s truck and individually tested before installation in the transmission.

6R140 Scorpion Signature Series (2011-2017)

The 6R140 is the most robust transmission (in stock form) ever put into a passenger truck. However, due to cost restraints, Ford elected to use a lesser-cost, piston to apply and balance the overdrive clutches. The OE piston design only applies a minuscule surface area to the steel plate. Over time, and with heat cycling, this causes the steel and clutch plates to adapt a formed memory. This coning causes two further issues.

First, clutch pack clearance is reduced which causes drag. This drag then causes the pack to fail as it is being partially applied. Secondly, the coning does not allow the full contact face of the clutch to apply and this causes reduced torque capacity and again rapid failure.

transmission upgrades

Like the other models, the RevMax high-performance automatic transmission is engineered to withstand higher horsepower and torque levels compared to the factory transmission, making it an excellent option for those seeking to upgrade their vehicle’s performance capabilities.

These transmissions are upgraded with increased clutch capacity, improved clutch plate material, phosphate steels, and ZeroFlex technology.
