Trans service kit installation

I like to quote ahead of time to avoid the confrontations. They vary all over the board. Unless there is something obstructing the pan from removal, I get an hour r&r time. I qoute about $25 of dextron III if that is the fluid it calls for and get a few dollars for chemicals and rags. The kits I use are the filter king from advance and most often do a markup of 2.25 times the cost of the kit.
