Sonnax Transmission Parts
Part # 35922-01K. TH350 Speedometer Hole Plug. During high performance rebuilds, the speedometer gear is often removed and replaced by a freeze plug. However, in addition to being used for driving the speedometer, the gear is also critical to lubricating the rear output shaft bushing. This new speedo plug supports the speedometer gear and allows lube to flow as the original design intended. The gear shaft has to be cut to 1.320" long. Cost $24.00
