Changing the tranny fluid...

[ricky_db]

i just changed mine last weekend at like 145k.. dont realy feel to much of a diff it still slips a lil bit and i dont think we have a tranny filter. i went to NAPA to get the fluid and the filter to knock them both out at the same time (thinking i had a filter in the tranny i could get to) NAPA sold me one and everything. so i open the tranny up NOTHING! no filter and the gasket was to big :oops: so i just changed to fluid and called it a day.. after returning the filter to NAPA

Did you buy the Mitsu spec trans. fluid? From what ive heard, the 99 Galants have an external trans. fluid filter. The newer Galants have an internal filter. I was told that my 03 had an internal.

Diamond SPIII ATF is the fluid that is required. But ive heard you can use an equivalent. Quite frankly i dont know shit about transmission fluid, so im not sure if Dextron 3 is the same. Hopefully someone can come clear this up.

Dextron 3 and Diamond SPIII are NOT the same. If you start having transmission problems like slipping, hesitation or noise when you drop it in gear, it's because you put the wrong fluid in. There are a couple of equivalents to Diamond SPIII that I noted in a previous post, but some people are having trouble finding them. If I were you I'd drain that fluid and replace it with the Diamond SPIII or equivalent. Chalk the experience up to not using the search button.

Yes my 99 has transmission filter on top right next to the dip stick and looks similar to an oil filter, costs 25 at dealer. My 02 does not have an external one.

Mind posting those equivalents? I think i read somewhere on these forums that it was Diamond SPII, I and M??? Those are supposed to be the equivalents i think. :?

I know all the warnings about only using Mitsubishi Diamond SP III, yadda, yadda, yadda. However in the last couple of years both Castrol and Kendall have manufactured new formulas of transmission fluid that are compatible with our auto trans.

Now before you guys go flaming me, both products are guaranteed by the manufacturer, both of which are major lubricant manufacturers. Secondly, I've been running the Castrol Synthetic for about 13k miles and I push my transmission as hard as anyone else. I've had no problems and none of the symptoms associated with using non-mitsu fluid. It's your choice, just know that there are alternatives out there.

Castrol Multi-Vehicle ATF Synthetic

Kendall VersaTrans ATF

Check with your sources and verify what I found out.

Wow. Thanks. We carry Kendalls at my job at Goodyear. Good info! :smt023

Make sure the Castrol stuff you buy is the Import Multi-Vehicle ATF... my local auto parts stores don't stock the import stuff.
