• Lower
• Because a housing is structural, a visually identical replacement from a different variant can have different internal clearances or a different mounting face.
• If the original is cracked, find out why before fitting a replacement, since a housing that cracked from a misaligned mount will crack again.

A housing is usually matched to a particular transmission or engine variant, and the casting number on the original is often the only reliable identifier.

Match this against the part you are taking off rather than against a photo. If the number is unreadable, send us the VIN and we will confirm it. In stock and sent from the US in one to two business days, free delivery over $59.
