Aside from these codes stored there are others like lost com with abs, ECM/pcm, transfer case. It’s my dads truck, from the start I noticed it was wet with trans fluid underneath. It was leaking from the main plug to the TCM. I repaired that, cleaned the plug connector, new filter and new gasket, added fluid and still the same issue. Now I’m leaning towards removing and or replacing the mechatronic assembly but I’d like to know a way to confirm a fix for the issues I’m having which is delayed shifting (very delayed) when cold and once warm near impossible to get it to shift… any advice would be great.. it’s the 6R80 trans.
