Question ??? Lean Oe Rich Mixture Cause Detonation/ping???

which A/F mixture causes detonation/ping? lean or rich?
would a rich or lean mixture cause tranny issues like when i floor it at 70 it will go, kick, then go again

If a motor is lean it will be more prone to detonation. The fueling is not going to cause transmission problems, but can cause stalling, bogging, or hesitation.

lean will cause detonation which will cause the ECM to pull timing which MAY cause bucking.

my car after cam install ran lean and the transmission was feeling like it was slipping and going to fail, tuned the ve table and I was amazed to say the transmission problem is gone for ever! I think the engine was hesitating and caused the trans problem.
