Flat-Rate Shipping

Car Part Planet offers fast flat-rate shipping to commercial addresses in the continental United States. This does not include home-based businesses, only registered business addresses that are commercially zoned. The shipping location should be capable of receiving our products without prior notification and with the capacity for unloading with a forklift from the delivery truck. Please note that residential addresses or locations that require a liftgate for unloading will need to pay a $99 liftgate fee to the carrier.

Typically, you can expect to receive orders from us within 2-4 days if the product is in stock, excluding holidays and weekends unless otherwise stated. Please note that in certain remote locations in Colorado, Utah, New York, Oregon, and California, the delivery may take longer and may require additional fees.

Even though our order volumes are always increasing, we always strive to ship our products as quickly as possible. Please understand that all shipping times are estimates and are not guaranteed times for delivery.

Please note that all remanufactured transmissions are DYNO-tested prior to shipping. In some cases, damage can occur during the shipping process. It is important to carefully inspect your products when they arrive and promptly report any damaged or missing components to our friendly and helpful customer service specialists.

If shipping damage occurs, we will collaborate with you to find an efficient solution and deliver an excellent experience. Please be sure to inspect your products carefully before signing the delivery paperwork. Failure to do so will place the responsibility on the receiver.

Core Return Policy

Car Part Planet assumes all shipping costs involved with returning your core (old part) to us. That means that there is absolutely no cost to you. However, it is your responsibility to initiate the core return. We will make it simple for you!

Once you have your new part installed, just give us a quick call at (888) 412-2772 , or stop by our Core Return Page and arrange to have your old part picked up.

We care about our customers and keep our prices as low as possible. That's why we must receive your old part back. We don't require an upfront core charge, which allows you to schedule your core to be picked up within 30 days from the date your new part is delivered.

If the core is not returned within 30 days of delivery, your warranty will be voided. Additionally, if you do return the core after the 30-day grace period, there will be a $50 processing fee.
