Sometime earlier in the year, my transmission would occasionally, perhaps twice weekly, not want to engage into first gear after coming to a full stop; it was as though the car were placed into neutral. Perhaps six months earlier than that, the transmission had been given a full flush. The folks here recommended Sea Foam which advice I followed. The condition slowly faded away, I cannot remember the last time the transmission misbehaved. So, while I am not a big believer in miracle products, Sea Foam, IMHO, is worth a try.
