When do I purchase ETC coverage?

If you take delivery of a new vehicle from an outlet not offering ETC coverage, you are still eligible to purchase coverage through an Allison Authorized Distributor or Dealer and do not have to return to the outlet.
How do I pay for the ETC 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 ETC 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?

No, the remaining coverage is not transferable to your new transmission. The ETC coverage purchased stays with the transmission.

Is support equipment and electronic components purchased from Allison covered by ETC?

Yes.
If I do not use an Allison Approved fluid will Allison Transmission cover my repairs during my ETC period?

No, not if it is determined that the vehicle has been operating with fluids other than Allison Approved fluids.
