Wow good to know! Very good to know. I had no idea!

Was at work all day and this is new account because forgot password to old account on here. Thanks for advice! Good to know. I was thinking that pulling a full loaded rv (I have a huge battery bank, much to big for it, and two propane tanks. I live in it full time) could cause the fluid to change. I also did some pretty steep climbs (slowly) with it loaded. I am amazed these little guys can do what they do. Maybe a flush will do it. I will keep overdrive on from now on. Have been checking fluid often, so hopefully will avoid future problems. I hope! Lol

1987 Toyota horizon 22ft 22-re EFI The previous owner told me that the overdrive must be turned off while driving in town, and when on the highway, you turn it on. I found out that it should have been on all the time, unless there is a special circumstance. So I drove with the overdrive off for about 3000 miles. Did turn it on here and there for highway, but not all the time. Now the fluid is black. I drain and filled twice and filled it up without over filling it. Still black. Improved color, but surely still black. have used shop pump to take out as much as possible. Also ran for 10 seconds to get as much fluid out as possible. It shifts smoothly and works well from what I can tell. No issues there besides the black fluid. Should I be concerned? Any comments would be greatly appreciated!
