While the similarities found in the A4CF2 and the F4A51 transmissions allow you to use the ATSG – F4A51 manual for disassembly and re-assembly, the true value in this guide comes from the complete and extensive valve body information on the A4CF2 which is significantly different from the F4A51 and has not been provided by the manufacturer.

In addition to the valve body information solenoid function, electrical information, operation, specification, and complete hydraulics and case passage identification are also included.  Found in the 2006 and later KIA Spectra and the 2007 and later Hyundai Elantra this guide is sure to help you diagnose and properly repair malfunctions of the A4CF2 transmissions.
