Gentlemen,
I own a 2015 Hyundai Genesis (aka G80) 3.8L v6 with 8-speed automatic transmission. The car runs great except that it recently started to shift harsh from 4th to 5th gear. I looked it up in Genesis forums most opinions are about solenoids that may be the cause of this harsh shifting.
I just recently drained and filled the ATF fluid 3 times in row; still the issue persists and still does harsh shifting from 4th to 5th gear. I did not change the solenoids yet; no DTC codes in the OBD2 scanner either.
Hence my question: is there an ATF additive that I can add that may be able to clean the shift solenoids over time and helps with the shudder or harsh shifting? I primarily am looking for an additive that cleans the solenoids and not looking for something like Lucas Stop Slip or the like.
Your thoughts will be appreciated.
Thanks,
Husam
