[Tobra]

Fluid was in the transmission a long time in the wife's ride. It had like a little shudder it would do if you had a full load of people in it going up a hill. It has the drain plug on the side, so I slid under there and drained it, about 3 quarts, came out plenty dark. It was better, but was still pretty dark on the dipstick. Drove it a bit, repeated the drain and fill, and the shudder it had under load resolved, looks nice and red wiping the dipstick on paper towel now.

I am a bit dubious about the idea of killing your transmission with cleaner juice in it. I suppose there are exceptions. If it did make it worse, maybe you could put some of the dirty stuff back in it. Repeating the drain and fill helped in my case. Can't remember what that Castrol stuff cost, but it was like $20 to do the service. There are like a bazillion different kinds of ATF
