2005 Saturn Ion fluid

theres a drain plug on the bottom of the transmission its a 24mm head thats where u drain it no filter to change it takes about 4.2 quarts the dipstick/fill hole is held down by a 12mm bolt.i would recomend using the saturn fluid.let me know how it comes out.

just changed fluid it has a inside filter ! no drain plug .not a hard job thanks for your input!!! alot of auto parts resalers say you have no filter or you got to break the case apart -i found that to be untrue -just a regular filter like any other...

Iam sorry I was thinking of the 03 04 ion they changed the transmission to the ls transmission in 05 that one has a filter and takes close to 7 quarts it has a level hole no dipstick u fill it idling in park till it just starts to come out of the level hole.is that how u filled it?

put in 4.5 quarts ,parts store said 4.2

The 03 04 trans without the removable trans pan took 4.2 Mitchel on demand says drain and refill for ur car 6.9 quarts.let me know how it goes.

i captured most of the fluid and it filled a gallon jug and eye ball guessed it -had car since it had 11000 miles so it was not changed ,figured it was close . didn't drop much on cardboard so replaced what was in it...
