| Need to get a something straight. One, changing the motor oil will have absolutely no effect on the transmission. It sounds like one of two things happened. One, the shop did not add enough oil. If you wife added 4 quarts, it appears all that was put in the engine was one quart. Or the engine was filled with oil put the drain plug was not tightened properly and the oil leaked out. Long before the engine started running poorly, the check engine light should have lighted telling your wife something was amiss. You need to contact the shop that changed the oil and ask about filing a claim for the damage to your vehicle. If they do not cooperate, your only option will be to sue. |
