Hi there, thank you for the donation.

It is critical the the correct transmission fluid be use as mixing incompatible fluids can cause damage, this transmission this should only use genuine Toyota trans fluid Type T IV (AFT JWS3309 0R NWS 650) There is a TSB dated May21st 1999 that covers transmission oil, i highly recommend that you return the car to the work shop that did the transmission work and ensure that the correct oil is used as if not this may cause serious damage to the transmission.
