One of our local members had to have a conversion in order to drive a Viper (physically limited). It was done by a tuner in Houston and was a disaster. Woodhouse Dodge has since worked on his car and gotten it running very smoothly with the auto. Don't know if they would do a conversion, but they could definitely tell you how it was done to get it right. Try Rick Maxwell at (800) 889-1893. Good luck!
