Hyundai Motor Group A4CF1
The 4-speed modern automatic transmission A4CF1 produced in 2005 and its more powerful modification A4CF2 from Hyundai were designed for cars with the engine capacity up to 2 liters. Since 2006, these automatic transmissions can be installed on all FWD small cars of Hyundai (Accent, Solaris, Ceed, Getz...) and Kia (Spectra, Forte, Cerato, Soul...).

Common problems & symptoms
Problems and symptoms reported for this transmission, compiled from repair sources. Not a complete list.
!
VFS EPC Solenoid Failure
VFS (EPC) solenoids fail due to contaminated and overheated ATF from torque converter heat exposure.
!
PWM Solenoid Wear Out
PWM solenoids degrade from resource wear-out and contaminated transmission fluid clogging internal channels.
!
Valve Body Channel Clogging
Suspended contaminated fluid clogs and wears valve body channels causing oil pressure shortage in clutch packs.
!
Pump Seal Leak Damage
Long-term operation with leaking pump seal causes bushing damage and shaft vibrations leading to pump failure.
?
Friction Component Early Burnout
Early burning of friction components caused by oil pressure shortage from clogged valve body and solenoids.
!
Solenoid Wiring Fault
Faulty solenoid wiring causes electrical part failures, often misdiagnosed as solenoid hardware failure.
?
Vibrating Clutch Lock-Up
Clutch lock-up vibration occurs under low oil pressure conditions, accelerating pump and drivetrain wear.
?
Rapid ATF Contamination
High operating temperatures and forced torque converter lock-up accelerate ATF contamination and degradation.

About this transmission
Transmission general data
The 4-speed modern automatic transmission A4CF1 produced in 2005 and its more powerful modification A4CF2 from Hyundai were designed for cars with the engine capacity up to 2 liters. Since 2006, these automatic transmissions can be installed on all FWD small cars of Hyundai (Accent, Solaris, Ceed, Getz...) and Kia (Spectra, Forte, Cerato, Soul...).
The first modification A4CF1 had a lot of problems, therefore an updated modification named A4CF2 was released in 2005. Minor changes in electrical parts and computer settings were introduced in 2007 in order to prolong the transmission lifespan that may be comparable with the resource of the whole car.
Technical issues and repair guidelines
Typical problems during the first years of the transmission operation are related to change of ATF and filter replacement. It is recommended to replace all friction components together with the kit of gaskets and seals during the transmission rebuilding.
Common problems in A4CF2-\1:
The list of the most popular repair procedures for this transmission includes the valve body reassembly and replacement of solenoids. The most vulnerable failure-prone are VFS (EPC) solenoids and PWM solenoids. The problem is related to contaminated and hot (because of the torque converter) transmission fluid and resource wear-out. In many cases problems with electrical parts are caused by faulty wiring of solenoids.
Some problems may occur in the pump as a result of a long-time operation with the leaking seal, damaged bushing (applicable to A5HF1) and shaft vibrations.Specialists assume, that high temperatures and forced torque converter lock-up lead to rapid oil contamination and this suspended fluid clogs and wears out channels in the valve body and solenoids, leading to the oil pressure shortage in packages and early burning of friction components. A long-time operation with the pressure shortage and vibrating clutch lock-up leads to problems with the pump and some other unpredictable issues.
