Transmission shudder on other Ranger years
Report counts are for each model year on its own, so a newer car has had less time to collect them.
What this problem usually is
This is the biggest drivetrain group on the site: a transmission that shudders, slips, hesitates or bangs into gear. It's the everyday version of transmission trouble, where the car still drives but doesn't drive right, and it has three narrower sheets of its own for jerking, hesitation and slipping.
What got replaced
Owners who name the part that was replaced mention the transmission (5 reports) and the clutch (5 reports).

Is this a known problem?
The manufacturer has sent NHTSA 8 service bulletins or notices for the 2021 Ford Ranger that deal with this problem. Newest first.

What owners wrote
“Transmission hard shifts in low gear and sometimes slips gears or revs up engine without accelerating then slams into gear lurching forward. Had transmission oil checked by dealer and they said it looked great. Happened 29 July several times and again 5 Aug all throughout the day.”

“truck hesitates to go into gear then slams into reverse unexpectedly with a lot of force backing up - almost ran over a family member. Same thing when cold and going from park to drive, almost drove off my driveway down a steep mountain. I believe it is related to TSB 24-2046 No warning lights or anything, dealer has not been able so far to reproduce because the weather warmed up”

“While accelerating from a stop the truck went from 1st gear and then would not go into 2nd gear for a 5 seconds and then it engaged into 2nd with a harsh gear change. This happened several more times to various degrees of time out of gear and not engaging into gear.”

“My truck loses power at a stop, starting to accelerate is stalls in the middle of the road. It seems to be stuck in gear or not going in gear. It will finally start going and the hesitation starts a the rpm gage goes up to about 3000 rpmâs and then goes back down to 1500. This is extremely dangerous to lose power in the middle of the road. This needs to be addressed.”

Should you keep driving it?
This page can't tell you that. 2 of 35 reports involved a crash. Owners who file are the ones who had a bad experience, and nobody checks their reports. If the problem affects steering, braking, power or a fire risk, treat it as a safety fault and have it inspected before a long or high-speed drive.
