I was told by a transmission shop that the 6L80/90's wear the torque converter out pretty fast due to the amount of slipping they allow. This was mainly referring to truck stuff, not sure about car stuff. I'm partly asking because, my engine/trans combo has 60k on it and the pan was full of friction material. I tore it completely down and checked all the clutches and they all looked good, so I figured it came from the torque converter.
Is this true? Should I change my table to allow less slipping? Anything else that should be done? This is a swap.
Any thoughts are appreciated.
