Flat-Towing Manual Transmission Vehicles

July 10, 2017

Flat-towing manual transmission vehicleA recreational vehicle gives you the freedom to explore our great country. Many people extend this freedom by towing a vehicle behind their RV to use for sightseeing or running to the grocery store once they have set up camp. A TOAD (or dinghy, in RV language) is the extra vehicle you tow behind your motorhome.

With few exceptions, the transmission of every dinghy has limitations as to how far and how fast it can be towed before the transmission will be damaged. This applies to both automatic and manual transmissions. But there are steps you can take to prevent this from happening.

 Don’t Trash Your Tranny!

As a vehicle is being driven, transmission fluid circulates throughout the transmission, cooling, lubricating and cleaning internal components.

With the exception of some four-wheel-drive and all-wheel drive vehicles, a transmission must be in neutral if the vehicle is being towed on its drive wheels, such as being flat towed behind an RV.

In a TREMEC-equipped vehicle, rotation of the rear wheels (even in neutral) causes the mainshaft to turn. Without being engaged in a gear, the cluster will not turn and no lubrication will be fed to critical parts.

In this state, the mainshaft will spin minus the necessary lubrication, until it burns up the needle bearings under the speed gears and/or the pocket bearing between the mainshaft and input shaft.

When towing a TREMEC-equipped vehicle with the rear wheels on the ground, the driveshaft must be disengaged. Disconnecting the driveshaft prevents the transmission from overheating and also wear and tear to the transmission’s components.

There are a number of ways you can safely pull your TREMEC-equipped vehicle behind you: trailer, tow dolly or flat towing.
