best price on a Tru-cool H7B transmission cooler

Great prices and quick delivery. Email response on purchase and follow up very good.

Great so far.

Best price on the web! I hope that shipping is also quick.

Was easy to find the correct parts.

Shipping is too expensive.

Happy with purchase

It is the way all on-line purchases should go. I got the item in 2 days, even before the email that it had shipped! Only negative is that the shipping cost was 35% the item cost. But it was still less that others with "free" shipping.

Awesome

Easy to use website

The parts were perfect! I will definitely buy from Autoplicity.com again! Thanks for being AWESOME!!

Cheapest around, excellent shipping, easy to use website! ill be back!!!

Your site said if I signed up I could get a discount of some sort. Did not specify the amount. Would like to have that applied.
