pacific coast transmission sells defective parts and does not warranty them. lomita, California

This shop sometimes sells rebuilt valve bodies on ebay. I bought rebuilt valve body, part was defective as it was not adjusted properly and gave hard shifting on transmission when cold... Bought off ebay, owner of shop waited to send part till i could not file complaint on ebay or paypal. Numerous calls to owner Johhny, every time i was informed that he would send me another part and swap out the defective part. Never sent any part or gave any tracking information. They never sent a part to swap out. So now i have a car that shifts worse than before and no help from this shop. Got dealership confirmation the part was bad and Item was stated to have a 12 month unlimited mile warranty, this rebuilder does not honor their warranty and will give you a run around till you give up trying, Avoid at all costs!
