Stopped by the dealership this morning to pick up some transmission fluid for my 92 500E and they handed me a bottle of Castrol Dexron. I just wanted to make sure this is the correct fluid to use before I mix it with my existing fluid changed about a year ago. I'm just topping off with this fluid.
On a seperate note, I'm considering changing to Schaeffers Transmission Fluid and was wondering how many have tried it and had better results with it. It's not a synthetic so it should be safe, but is it better than the Castrol or am I wasting my money?
Any other tranny oils worth considering?
Thanks for your input everyone.
