    For a transmission type similar to the 4L60-E this is equivalent to 2nd gear. For another type of transmission combination the braking capability should be verified. For manual transmissions, engine braking is calibrated with the GM transmissions to occur in the highest ratio in each forward selector range Some off road applications or very heavy load situations might require additional subsystems to increase engine brake capacity.
