At what milage is both due about, thanks. When do you guys do it?

 

you mean transmission oil change? and tune up?

i did my tuneup at 30 k and tranny flush at 40 k

 

I changed the plugs at 45K and flushed the transmission @ 20K. The trans flush is a cheap preventive maintemance and I highly recommended that you should replace w/synthetic oils, such as RedLine/Amsoil products.

 

I Did My Tune Up At 35 And My Tranny Flush At 50. It All Depends On How You Drive.

 

tune up for me at 106K miles
Trans every 60K

 

The manual says tranny oil should be changed every 30,000 miles.

 

It's not necessary to replace at 20k especially when using Amsoil tranny fluid. I have a comparison picture of Amsoil and conventional tranny fluid after 50k. Amsoil still looked super clean compared to conventional which looked black. I'll see if I can find that picture and post it.

 

now i recently just purchase my 00 se and it only has 44k...i check the tranny fluid and it has a light pink color to it which tells me it's still fair new...should i change it anyway?

 

I know it's probably not necessary to change it at 20K interval but this practice is a preventive maintenance in my book, for the auto-trans.
After 20K under the Redline fluids, I noticed a change in color w/the new Amsoil oils running through the flushing system. Now, the change in color does not neccessary dictate whether the oil is still fresh or not...only if you sent it out for proper oil analysis. Since I live in NortherEastern location, the variant of temperature changes and also I often taken my car for a long trip, justified why I flushed out the system that often. It is a cheap insurance until I install the trans cooler in the future to perhaps prolong the oil life.

 

Oil every 3 - 4K
Tranny Fluid every 30K if dark in color
Tune UP? What does a tune up consist of these days?? Plugs & wires every 100K
