Only when starting off problem occurs. Has also caused a scenario where there has been no forward or reverse at all, but regained in a couple of minutes. Checked solenoids and they all work. also changed speed sensor still the same. Car doesn't slip in hills or under load when moving.

Good morning,

I would start by changing the fluid. I may be dirty and not allowing the proper flow of fluid for application.

Had previously added 2 liters to transmission as fluid was blackish. No problem until 2000 km later. Had pan off to check solenoids and only a small amount of wear material present.

When did you have the pan off? Black fluid is burned fluid and not good.

Had it off a few weeks ago when I took the solenoids out to check them. There's still a bit of reddish color when on a paper towel but mostly black. Does not smell burnt. I would say it was never changed. I bought it off a guy a few months ago, was working perfect.
