Our 4T45E Updates and Upgrades

How Many Variations of the 4T45E?

Remanufactured 4T45E vs. Rebuilt or Used

Reman 4T45E vs. Rebuilt 4T45E?
Both are good options but the best option for you depends on the transmission problem, the year, make and model of vehicle, the mileage and the vehicle value. What kind of warranty coverage are you looking for? Remanufactured transmissions carry a longer, 3 year, nationwide warranty with additional upgrades while a rebuilt unit generally carries up to a 1 or 2 year warranty and upgrades vary from shop to shop.
Reman 4T45E vs. Used 4T45E?
Buying a used 4T45E transmission may save you money. However, if the unit does not work properly after installed, you will more than likely have to pay the labor again for removal and reinstall of the transmission PLUS the freight to ship the transmission back to the salvage yard. The additional cost may be higher than installing a reman or rebuilt transmission–not to mention the extra downtime. Warranties for a used transmission is only 30 days, 60 days, 90 days or 6 months. Used transmissions, since there is no way to know how many miles are on them, may fail at any time.
