Review on 🚦 ACDelco 3987921 GM Original Equipment Automatic Transmission Speedometer Driven Gear - Reliable Replacement for GM Vehicles by Michael Onwukaife

The part supplied was fine and worked well but this part fits in the gearbox and only uses one and I had to buy two "packs of two". I will probably never use any other gear again and this isn't an item that many people can use. After this purchase I found the exact same product at Rock Auto where I could only buy one and cheaper for parts and shipping. After that, I'll most likely go to Rock Auto before Revain. Don't know if that helps, but thanks for asking. Roger.
