maintaining my 2005 dodge ram 1500 question?

[Pecos]

hello,
i have an 05 dodge ram 1500 with 60,000 miles. i recently bought a new battery. i'm trying to maintain it before anything goes wrong...so i'm reading the owners manual.

which of the following should i do first? i pretty much want to do all three but i dont have the money to do them all at once.

1) change spark plugs and ignition wires

2) change transmission fluid and filter

3) flush radiator coolant

no-2,change tranny fluid and filter, the plugs will go a little bit farther but the transmission needs to be serviced regularly,that would be my first choice and i own two of those trucks,good luck.
