1999 explorer 4x4 auto trans problem/166k miles

harsh shifting sometimes from when you take off from a dead stop. Are the solenoids going bad or is this an AT rebuild??

Not to be overly simplistic but make sure fluid level is up....lower level will cause this symptom -- could have minor leak at pan. Also, I rarely recommend snake oil in a can....but "Lucas Transmission Fix" will likely temporarily alleviate symptoms and buy you some time if short on cash for repair / rebuild. Had same symptoms on old Aerostar and put bottle in and ran smooth afterwards for months and months until returned van to service company -- didn't hear of rebuild even after that.

Most issues of an automatic come from the VB, solenoids, or accumulators/springs messing up. Replacing those and a VB kit usually solve most issues, besides fresh full fluid and filter.

Are you getting any trouble codes, or just the harsh shifts?
