Since you don't do a lot of DIY's I'd haggle the labor price a little and have them do it right. Don't you know someone on here that could do it cheaper for you?

 

The operation of my AT is too critical, since I have never worked on one I'll find a shop to do the job right. There's a few good trans shops in my area, need to find one that doesn't charge $300 to install a $90 item. It's called, "Shopping Around!"
