4 Q of ATF was used for my 150,000 miles 2006 Honda Civic Hybrid instead of 3Q of CVT when transmission fluid was changed on 12-16-2013. After driving 2 months and 1,500 miles the transmission started loud tack tack tack noise when deceleration. The car is parked and not driven now pending on the solution. Went to a Honda dealer for inspection and confirmed that wrong fluid was used and sample saved. Also confirmed the loud noise was caused by transmission. However Honda USA tech line disclosed that manufacturer did not test CVT with ATF therefore only suggested flushing the transmission with CVT. Checked on the Internet but could not find any similar case with supporting details such as what’s the symptom after using wrong type of transmission fluid. Also did anyone try flushing the transmission with CVT and if tried what’s the result. Another question is anyone replaced with an used transmission and how the cost was paid.
Appreciate any help.
