Automatic Transmission - strange sound after flush/fill
I know you dont want to hear this,...but. Find a larger Hyundai dealer near you,(or a new fangled GENESIS dealer). They really know their way around the ZF stylr 8AT. Bring 9 qts of CERMA AT with you and pay for labor only fluid change.
Some on here take a whack at draining and filling. WRONG ! The ZF style 8AT needs to be pressure evacuated, and pressure filled. End of story.
Beyond that proceed at your own risk, and yes, you will encounter little "occurrences" like you have.
My Hyun expert did mine while he was still the lead master tech at my dealer, he had the car for at least 3 hours. Did the pressure drain and refill. Ran it to opersating temps, checked the level, added, repeat. Bottom line is with these transm, its a bit tedious to get it right.
(He has his own biz now).I did mine at 19K, and will be replacing it again at 65K Severe duty maintenace requrements are change ATF every 45K. If you are N/A tuned or turbo anything,....thats severe duty, period.
And to end any bunk, CERMA ATF can be used in any transmission made, and exceeds all standardsand requirements including ZF's.
It re-elasticizes even burnt and damaged seals.
