When vehicle first came in, customer stated that the transmission was slipping. We confirmed that the transmission cooler lines were rusted and leaking transmission fluid. We informed the customer that the transmission fluid smelled burnt, but due to the lines leaking we were unable to perform proper pressure tests to tell if transmission had internal damage. The customer was warned before any repairs were performed that replacing the transmission lines was necessary, but the transmission may also have to be replaced. We will contact customer and are more than willing to work with customer on price of transmission repair / replacement.
