HIGHTEC ATF CLEANER is a highly-effective additive composition that cleans the oil circulation and inside of the automatic transmission. By removing the soiling, the transmission and the new transmission oil remain clean for longer. HIGHTEC ATF CLEANER is suited for all automatic transmissions with or without torque converter lock-up clutch. It is used for difficulties with gear changes or switching shocks, starting weaknesses, plucking torque converter lock-up clutches, kick-down problems, vibrations, and unusual transmission noises. It is also used after repairs to defective heat exchangers to remove coolant residue.
