Today's larger, heavier motorhomes demand higher horsepower and torque
for increased acceleration. Bigger engines require a transmission that can
handle the horsepower. The Allison MH Series Automatics match your needs
with increased ratings and performance. Call 1-800-252-5ATD for the tools
to help you select an Allison Transmission. You'll see this beautiful country
like you've never seen it before. |
