Thanks for the response. I will have to check for drain/fill plugs as "requiring no maintenance" for the transmission does not compute for me. I hope it does cause at 100000 miles, it's prolly a good time for a changing.
Where is the transmission dipstick located on the 2004 GX470? I for the life of me can't see it. Noticed the radiator has a small leak and if sealant doesnt fix that I will have to change the radiator which would involve disconnecting the transmission cooling lines and I imagine topping off the tranny. Any help would be appreciated.
