All transmissions shall be provided with a power takeoff provision to include gear and opening except if otherwise specified.

All cab and chassis items furnished with a transmission that includes a PTO opening on the transmission shall be furnished with a PTO engagement control switch located on the dash. The switch can be either air over hydraulic or electric over hydraulic depending on the transmission furnished as standard or optional.

All transmissions must be filled with the transmission manufacturer’s required synthetic fluid to provide maximum warranty coverage. Manual transmissions are those with straight cut or helical cut gears that remain in constant mesh and require a device (clutch) to disengage the input power flow from the gear cluster in order to change forward output ratios. The gear ratio changes are accomplished by the driver operating a lever which changes the set of gears that provide the power flow throughput. An automated manual transmission is one that uses a constant mesh gear system and clutch that is controlled and gear ratios changed by a computer controlling servos. A dual clutch transmission uses separate clutches (and separate gear shafts) for the even-numbered and the odd-numbered gears. In this way, the next expected gear is pre-selected. When a shift is required, the controller disengages the clutch currently in-use while simultaneously engaging the clutch not currently in-use, thus making a smooth and fast shift.

When a towing package is specified by option the transmission may need to be upgraded to handle the load of the truck and trailer combination. The total load shall be calculated by using the empty weight of the truck at operating curb weight with a full tank of fuel and the added total weight rating of the trailer hitch. When the truck and trailer hitch combination will exceed the capacity of the standard equipment transmission a collision shall be set in AutoChoice. This collision shall be a “requires” statement for a transmission or creating an “or” statement when a list of transmissions can be selected from to handle the loads that will be imposed.

3.4.5.1 DRY PLATE CLUTCH

The clutch shall have a torque capacity exceeding the maximum delivered engine torque. The clutch shall be equipped with a greaseable bearing. An extension hose or tube shall be installed to make it easier to grease/lubricate the release bearing.

3.4.5.2 AUTOMATIC TRANSMISSION

An automatic transmission uses a fluid coupling (torque converter) with gear changes accomplished by locking and unlocking a system of planetary gears. The transmission shall be provided with a live power takeoff provision except when the transmission required does not offer a PTO provision. The net torque capacity and the net power rating of the transmission shall meet or exceed the output ratings of the engine in all gears. Allison transmissions shall be filled with Allison TransSynd or other TES295 approved synthetic fluid to provide maximum warranty coverage and extended drain intervals. The Allison transmission shall be programmed for a performance oriented shifting to allow the engine to reach maximum RPM under heavy load conditions in all gear selections. The programming shall also provide for fairly aggressive downshifting from high speeds to help slow the vehicle with or without brake application. The programming shall also include a learn function which modifies the shifting based on driver use.

3.4.5.3 TRANSFER CASE

A transfer case shall be provided on 4x4 and 6x6 vehicles. Unless the transfer case is equipped with devices which compensate for differential torque and speeds between front and rear axles, the transfer case shall provide for driver selection of either four-wheel or six-wheel drive. Inter-axle compensating devices shall provide for positive transfer of power to all driving axles. The speedometer shall read accurate vehicle speed with the transfer case speed selector in high and in low range. An overlay on the speedometer face may be utilized to indicate accurate speed in low range.

3.4.6 DRIVELINE COMPONENTS

Driveline components shall be rated to transmit the maximum delivered torque of the engine, as developed through the maximum gear train reduction. Components shall be rated no less than the GCWR required for each item. Drivelines shall be balanced and free of vibration. The drive shaft for front mounted winches shall have an angle not greater than 16 degrees from the longitudinal plane.

3.4.7 FRAME

Specified frame resistance bending moment (RBM) is calculated by using the section modulus number and multiplying it by the known yield strength. The minimum required RBM for each Standard Item is listed in AutoChoice under Minimums.

3.4.8 SUSPENSION

The vehicle shall be equipped with a suspension system with components having a rated capacity at least equal to the load imposed on each member, measured at the ground, with the vehicle loaded to specified GVW. When suspension is rated at the spring pads, un-sprung weight shall be deducted.

Hydraulic double-acting shock absorbers shall be provided on the front and rear axle(s). Only those suspensions that cannot by design have shock absorbers added can omit this requirement.

For dump, stake, wrecker, and carrier trucks with tandem rear axles the suspension system must be a walking beam type system with rubber elastomeric pivot points. Brands and models acceptable include Hendrickson HN VariRate, RT Series, Ultimax, Haulmaax, RS Series Rubber Walking Beam, Mack mRide, Chalmers 800 Series, and Daimler TuffTrac. When shocks must be positioned behind the rear most axle on dump trucks and they are not required by the suspension system, they should be eliminated to reduce the body overhang past the end of the chassis.

3.4.9 AXLES

Axle ratings shall be at least equal to the load imposed on each axle, measured at the ground, with the vehicle loaded to specified GVW. The wheel bearings and axle spindles shall be oil lubricated or of a unitized, lifetime sealed no-maintenance design for non-powered axles. For oil filled hubs, a window shall be provided for visual determination of oil level and provisions for venting or withstanding internal pressure buildup and for replenishing the oil supply shall be provided.
