Mechanics, make a note that the erasable programmable read only memory (EPROM) has been replaced by the one-piece transmission control module (TCM), which is needed to operate your unit’s HMMWVs.

If you have a HMMWV that’s NMC because it needs a 2-piece EPROM and you try to order a replacement for it, your requisition is going to be rejected.

You also don’t want to order a transmission because it won’t come with an EPROM.
