I was wondering, could the secondary incorrect airflow is the cause of my po730 code or probly needs new trans fluid

Poly-Boi Masaniai

Po730 just went off when I start car in the morning, drove around N came back about 30 min drive which really makes me think its just need new fluid change.... What you guys think..... Ill keep it posted after my trans fluid change if any changes occur.....


I will definitely replace the fluid with a new filter but I tell you this. Faults for incorrect gear ratio is not good news after racing and putting stress into that Trany. The car is a 2002 and I'm sure there is some good miles in that car. Replace the fluid and filter and drive it and if persist then you need to rebuild the Trany for wear out discs. Ariel.

There is a procedure on how to doit. Just start the car and remove the big Allen bolt while the car is running and if doesn't

Leak any fluid then you need to top it off with fluid until begging leaking and to do this you can use the small drain plug to add the fluid and see it leaking on the big one. If you google the instructions you'll get the right procedure your Trany should be a 5hp19
