Installation Notes

Verify the transmission and engine application before installation, since this part is listed across a wide range of manual transmission vehicles. Inspect the crankshaft bore and surrounding components for wear or damage before pressing in the new bushing. For best results, compare the removed part to PB656HD and confirm the fitment notes for your exact Chevrolet, GMC, Pontiac, Buick, Oldsmobile, or Jeep application.
