I have a buddy who while servicing his transmission in his Superduty, was given the wrong fluid at the Ford dealer. Long story short, he ended up with about 5 quarts of Mercon SP in his 4R100 trans that calls for Merc 5. He is going to flush out as much as he can, and replace with fresh Merc 5.
Does anyone here know of any incompatibilities between the two fluids, and of any problems that might arise from the mixing of the two fluids?
