Title: Speedo gear
Post by: sjfd04 on June 14, 2011, 09:53:48 AM

Anyone know what color speedo gear I should have for a ST-300 with a 3:08 gear set?

Thanks, Tom

Hi Tom,

Super Turbine 300 transmission with a 3.08 gears would need a (39 teeth) brown speedo gear. Part # 1359273.  They should be readily available at a Buick dealership or possibly an auto parts store.

Somewhere there is information that a black (40 teeth) speedo gear is correct. However, the three transmissions that I've had worked on, have had the brown (39 teeth) gear. I put a 40 teeth gear in my convertible once after reading that info. In a short time that 40 teeth gear got chewed up. Went back to 39 teeth gear and all is fine.

Hi Bill,

Locally, it's just cruise nights. I hope to make it to either the BCA Heartland Regionals or the BPG Nationals. I have to make a choice soon. Hope to see you again soon.
