From the information given above, it is easy to conclude that the T56 ratios differ from one car to another. One reason for this is that not all cars have the same engine characteristics. Therefore, before making a decision to install a T56 transmission, it is highly recommended that you consult a certified mechanic who can advise you on what to buy and modify so as to get the most out of the T56 transmission installed in your car. Getting advice from someone familiar with these transmissions can recommend which OEM trans may work best for you. This could be an original trans from a Mustang, Camaro or a T56 Magnum transmission. The torque spread produced by a Camaro engine will differ from that generated by a Mustang. hence, knowing what best suits your car will enable you to attain maximum performance without forcing your engine to work in a rpm range that it is not optimized for.
