I recently took my vehicle listed above convertible to an import mechanic shop and they used a diagnostic code reader that gave the code P1786/ Transmission Ratio Plausibility. I was told, "There's an internal excessive ratio error, we will need to replace the transmission." I need help understanding what that means and if it means there is no choice but to replace the transmission. They want to charge $7,000 to replace it.
