Six and Ten Speed Transmission Strength
 

How much more hp and torque do the L90's support, compared to the L80's? How much stronger are Ford's R140 transmissions compared to GM's L80 and L90 transmissions? If an L80 and an L90 transmission were built up, would the L90 be inherently able to support more hp and torque than the L80? Also, would a built up R140 transmission inherently be able to support more hp and torque than built L80 and L90 transmissions?

The numbers (80, 90 and 140) pertain to Nm. For example, 80 = 800 Nm, 90 = 900 Nm and 140 = 1400 Nm.

Thank you.
