I am sorry for the long wait

using Dextron6 will not hurt anything at all it is just a better transmission fluid

most of the GM vehicles are not running Dextron6 and alot have changed over to Dextron6 when replacing older Dextron3 fluids

there is nothing to worry about it will not harm anything at all
