Hyundai Elantra, Over-full Transmission Fluid
Q: I just recently purchased a used ‘96
Hyundai Elantra with 66K miles on it from a local dealer. Upon a routine
check of the fluid levels I noticed that the automatic transmission had
been overfilled. I drained the excess myself and removed a little over
two pints before I could get the level down to the HIGH mark on the dipstick.
The transmission feels sometimes like it might be slightly slipping. How
can I verify if the transmission, is in fact, slipping? If it is, could
this overfill of transmission fluid have caused this slippage problem?.....Shaun
may have created a transmission problem yourself! Did you know that to
correctly check the automatic transmission fluid level in your Hyundia
uses a slightly different procedure than the norm? Hyundai requires that
with the engine running, the automatic transmission must be in "Neutral"
when checking the fluid level. If the transmission selector is in the
park position you will get an inaccurate reading. If you performed the
correct procedure for checking the transmission fluid level and you still
believe the transmission is possibly slipping, then you will need the
services of a transmission specialist to confirm the transmission is in
need of repair.
