I dropped off my Edge at the dealer this morning. It bucks or shudders when downshifting.
Accelerates ok, upshift is ok, drives ok at low speeds, but when trying to maintain speed on an upgrade, e.g. 40mph or 65mph, it shudders or bucks when trying to downshift.
Tach looks steady or maybe doesn't respond fast enough to show fluctuation.
Is this the TSS/OSS issue or is something else going on?
