A common problem with OE case dowel pins for the ZF5HP30 is weak construction, which results in misalignment or damage to the transmission case. The Sonnax dowel pin 85000-01 is a more durable guide pin between the engine block and transmission case, preventing the misalignment that can occur with the OE guide pins.
