2014 Explorer XLT trans shudder?

[DiosmioMan]

2014 Explorer with transmission shudder in 3rd gear (30-40 mph), like it can’t decide to shift up or down. I am sure this is the original trans fluid at 130,000 miles. Will a fluid drain and refill with a bottle of Lucas oil likely fix the problem?

I doubt it, as there's no fix in a bottle...although it may help somewhat.

No, Only use Mercon LV. Do 3x drain and fills, and drive a bit in between each one.
