I just changed my transmission fluid on my sealed transmission (no dipstick). I’m not too mechanically apt, at all, but I like saving time and money, and I like knowing how my car works so I’m not not totally at the mercy of a stranger who is working on my car. I still need to change the transmission filter and I’ll probably flush it too. I just did two drain and fills. Anyway, thought I’d share this with this wonderful supportive and cool forum. I’m still soapin too.
