Product Overview
The A4CF2 fully electronic 4 speed transmission in the 2006 Kia Spectra and 2007 Hyundai Elantra (HD) and later vehicles is much like the F4A51 transmission but with the valve body mounted at the bottom. The manufacturer does not publish any information about this valve body. This A4CF2 Technician Guide provides complete and extensive valve body information, solenoid function, operation, specification and identification, electrical information, complete hydraulics and case passage identification and OBD2 transmission codes. All of it designed to help you diagnose and resolve malfunctions with the A4CF2 transmission. ATSG's F4A51 Techtran Manual can be used for the disassembly and reassembly of the A4CF2's internal components on CD.
