When do I purchase EC coverage?

You can purchase EC at the time of the vehicle delivery or within 12 months of vehicle delivery.

How do I pay for the EC program?
You may include the cost with the purchase of your vehicle (with dealer approval), or simply write a check to the Authorized Allison Transmission Distributor or Dealer.
Will re-gears be accepted in to the EC program?
Yes, provided they are new Allison transmissions in approved applications.
If I decide to sell or trade-in my vehicle before my coverage expires, can the remaining coverage be transferred to my new transmission or eAxle?
No, the remaining coverage is not transferable to your new transmission or eAxle. The EC coverage purchased stays with the propulsion solution.
Is support equipment and electronic components purchased from Allison covered by EC?
Yes.
If I do not use an Allison Approved fluid will Allison Transmission cover my repairs during my EC period?
