## NHTSA's summary

TSB: Vehicles may display evidence of a fluid leak or fluid seep from powertrain components. This bulletin explains how to determine the differences between a fluid leak versus a fluid seep. Cases that are determined to be a ?leak? should be repaired accordingly and will be covered under warranty if applicable. Cases that are determined to be a ?seep? should be documented on the repair order and inspected at the next service interval. Follow the Repair Information in this bulletin to determine if the concern in question is a fluid leak or fluid seep and review the Repair Procedure section to address the condition.
