1972 Chevrolet C10 — my model year is in a recall article but my VIN is not

I'd want a measurement, not a hunch. Write temp, speed, and in-gear vs coast when the 1972 Chevrolet C10 does it — then decide on parts. Save the big job until that test fails. This is from a 1972 Chevrolet C10 in NYC with 254,500 miles. Keep sale price, fees, and rate as three different conversations. This is the version I'd tell a friend.

Don't erase codes until someone who can help has seen them. This is from a 1972 Chevrolet C10 in NYC with 254,500 miles. If they can't show the line item, I assume it's hiding.

Ask what changed right before it started. If a shop can't duplicate it on the 1972 Chevrolet C10, bring a video plus freeze-frame data, not just a story. If the cheap test changes it, stop and reassess. When does it actually happen? I'm in no rush to be a hero on it.
