Thanks Brian, for your reply. I'm sure it is better to flush because the first time I only had my tranny drained but it still had problems shifting into the high gear. Only when I had it flushed is when I never had any problems again and still haven't (except one cold morning last week it took a few moments longer to shift into overdrive when on the freeway). A friend told me I didn't have to flush it out every time, so, I wasn't sure about this.

I'm going to try the synthetic oil over the regular as well although most of my driving is usually "stop and go".
