How often should we change our transmission fluid...??
also i m using Amsoil transmission fluid.. how often (KM or miles) should i replace it...?

how come many ppl install Denson irdium(single head) in their Toyota V6 since the owner manal tell us never use single head spark plugs ... would that be a problem if we put single head spark plugs into a double head system...? cuz i m think to buy Bosh 4+ and denson irdum...thx...

To answer your first question, if you were using regular Dexron II or III ATF, you normally would change it at 60K or earlier intervals. Since you are using Amsoil synthetic...your intervals may go a little longer.

Denso Iridiums have a better spark than platinums...and they last longer 60K vs. 100k respectively. No it will not be a problem if you used Iridiums on your 1MZ-FE that requires double tipped platinum. Toyota used these plugs in this order for the 1MZ-FE V6:

94-96 Denso Platinum - PK20 Single Tip
97-01 Denso Platinum - PK20 Double Tip
02-up Denos Iridium - IK20

Get the Denso Iridiums. Most of our club members use Denso Iridium on their cars.
