Having struggled for some months with "hard shifts" that only occurred after having driven for some miles on my '99 Regal, I took it in to Everett for troubleshooting and repairs.  They took careful notes of symptoms and were great to work with.  They found the problems quickly and updated me by phone before proceeding.  I was a bit taken back at the cost, but I'm an older guy and everything seems to cost too much.  They were much quicker in completing all the work than I expected (all done in two days).  The real joy was taking it out and driving.  I was a bit skeptical (having had others try to fix it without any success).  The difference was dramatic--like driving a new car and much better than it has ever driven.  They delivered!  I'll remember.

Many thanks to Mr. Richards in Service for his stellar customer service.
