Transmission EPROMS
Beginning with vehicles produced in the early 1990's the Transmission EPROM can be replaced on some vehicles in order to address customer complaints that would normally be addressed by having to replace the Transmission Control Module (TCM). Service EPROMs are available for the following systems:
