I like NAPA for these type purchases - like Charlie says - any problems are quickly dealt with on the spot.

NAPA Part #2464859 - w/Solenoid, fits automatic transmission on-line reservation price is $52.72 plus a $22 core. Order it up, take your old one in and skip the core charge and bingo! You're good to go
