I’m thinking about doing my own transmission fluid change. Has anyone here done it themselves? I know there’s a big debate on it being lifetime etc. but I want to do it. I’m at 100k miles at the moment.
I don’t have tech stream, but I’ve been researching and it seems that tech stream is used to check the temperature. I’ve seen YouTube videos of people using a temperature scanner guns to get temperature readings. I know I’ll need a pump also. Is there anything else I’m missing ? Does anyone know which filter I’m supposed to use also?
Totally up for any advice that people are willing to give. Thanks!

Drop the pan and replace the strainer. Refill with around 3-4 quarts. Level the car with access to the transmission, remove the overflow plug. Start the car and wait until it reaches operating temperature by checking the pan temperature. If you have a proper level of the fluid, you will see a very small amount of fluid coming out. If you don't see any, add more fluid.
If you are insisting on replacing whole fluid, do drop-and-refill every engine oil change.

hi allusuc, read the posts in the ls460 forums lots of people chime in w opinions..
if you have a good indy, I would get half the fluid out without doing a whole change and replace with some fresh fluid.
this way it doesn't shock the tranny and gives you some fluid with heat dispersing properties.
everyone has a diff opinion on topic, but flushing tranny is not something to do.

I didn't drive it first. I drained it in the morning, also changed my oil then drove it. This is my third drain and fill in two years. The fluid was dark before I did it the first time. I'm going to do it again in 5k more miles. It cost me about 45 bucks for 4 qts. On ebay.

two questions: what temp do you wait for it to be? And also the overflow drain, is that opened with an Allen wrench?

thank you for all your insight. I will be doing it this weekend. Any additional advice? I’ll have the car leveled. Open the fill valve first. Then the drain valve. Measure the amount drained. Close up the drain valve. Fill new fluid in. Start up the car and wait for it to reach a certain temp. Unscrew the overflow bolt, then tighten it after it trickles. Then done!

At 100k, you should really change the strainer and the pan gasket.
