Hello out there,
I just acquired a 2002 Sonata with 32K miles on it. Not knowing
anything about previous service, I took it to the local Hyundai dealer
for the 30K service which included replacing the transmission fluid. A
week later I checked the level (engine running with gear in
drive position) and found the level just touching the dip stick. It
was nowhere near the hot mark.
I went back to the dealer and was told that there was a TSB from
Hyundai that said that when the level was where you think it should
be, the transmission is too full and subject to foaming and damage.
Is the dealer correct or is he covering for sloppy service?
