Re: GM 4l80e trans vibration in O/D when towing
I saw a local shop sell a customer a trans rebuild for the same issue your having. When the customer got it back it, did the same thing. In his case the engine was missing under load. Common issue's would be carbon tracked plug, plug boot, weak injector if it has 8, coil output if it has 8, or plug wire etc.
