Let's Review.

 

Q. What will I need to order?

A. Vehicle VIN # and current mileage.

 

Q. Can I install it myself?

A. Yes, Self-installation does not void your warranty.

 

Q. Does my old transmission core need to be out when the new transmission is delivered?

A. No, you have 14 days from the date of delivery to schedule your core return. Need more time? No problem, just let us know.

 

Q. How is the transmission shipped?

A. Transmissions are shipped via truck freight (18-Wheeler) through FedEx Freight or R&L Carriers. Depending on your location another carrier may be chosen to better service your area.

 

Q. How is the transmission packaged?

A. Your order will arrive securely strapped inside a sealed high strength polyethylene (plastic) container.

 

Q. How do residential deliveries work?

A. For residential deliveries, the carrier must transfer your transmission onto a smaller truck for delivery. The carrier will then call you directly to schedule an appointment for delivery. Because of the extra steps involved residential deliveries are $100 extra.

 

Q. What else will I need for install?

A. Depending on your transmission type some external components may need to be transferred over from your original transmission. For example, the neutral safety switch, speed sensor, tailhousing etc.

 

Q. Does the transmission come with fluid? What ATF fluid will I need?

A. Your transmission will arrive with approximately 1-3 quarts of full synthetic ATF in it from testing. The torque converter is already primed with fluid and does not need to be removed. You will have to top the transmission off with fluid before operating. We recommend using our full synthetic ATF or any popular brand full synthetic ATF.

 

Q. So, what's the total cost?

A. The price you see truly is the price you pay, no smoke and mirrors here folks!
