    Q:
    What are common causes of oil leaks in a transmission and Transfer Case Seal for the 2003 Chevrolet Blazer? Posted by Verified Customer
    A:
    Oil leaks in a transmission frequently occur due to wear of the extension housing oil seal and bushing (if equipped), or the speedometer drive gear oil seal and o-ring. You can Select Your Vehicle to see complete installation and repair tips.

    Q:
    Where is the extension housing oil seal located, and how can you check for leakage at the Transfer Case Seal for the 2001 GMC Sonoma? Posted by Elhadji S.
    A:
    The extension housing oil seal is located at the extreme rear of the transmission, where the driveshaft is attached. If leakage at the seal is suspected, raise the vehicle and support it securely on jack stands. If the seal is leaking, transmission lubricant will be built up on the front of the driveshaft and may be dripping from the rear of the transmission.
