2010 Edge Possible Transmission Issue?

[gus_19]

Here's a detailed list of what's been going on. Technicians at Ford are saying right now nothing is showing on diagnostics and they couldn't replicate issue while on a test drive. As hard as it abruptly stopped the last time, I'm pretty much concerned for my safety if it were to happen again but at a higher speed. Any suggestions on what I should do or look at?

2010 Ford Edge Limited
Engine Type: 3.4L V6
Current Mileage: 9,777.6
*No towing and driven mostly in city*

First Problem

January 5th, 2011 @ 1:00 pm: Traveling up-hill on at 40-50 mph. During
acceleration, SUV had a simultaneous jerk/loud clunk which felt like begin “hit
from behind”, “axel locked up” or “engine/transmission dropping out”. This happed two times within a 5 second period. Pulled over and shut SUV off. Re-started SUV after checking fluid levels and ran normal.

Weather Conditions: Wet and raining / 40-45 degrees
Road Conditions: Smooth blacktop / uphill
SUV Conditions: During acceleration between 40-50 mph / after running at normal temp (45 min)

Second Problem
Tuesday, January 11th, 2011 @ 4:30 pm: Traveling home from work at 25-35 mph. SUV had a simultaneous jerk/loud clunk which felt like begin “hit from behind”, “axle" locked up”, or “engine/transmission dropping out”. This happed two times within a 3 second period, and the TRACTION CONTROL light blinked 3 times. RPM climbed as if it were in neutral but then “grabbed” and drove normal.

Weather Conditions: Wet and raining / 35-40 degrees
Road Conditions: Smooth blacktop / flat surface SUV Conditions: During acceleration between 25-35 mph / after running at normal
temp (15-20 min)

Third Problem
Sunday, January 16th, 2011 @ 7:15 pm: Traveling to gas station (4 miles) and felt one hard clunk with a simultaneous jerk. SUV paused but then drove normal. Traction control blinked once. Filled up gas tank and began to drive home. While driving uphill at 25-35 mph, SUV had an extreme loud clunk/jerk which threw me into the steering wheel and almost stopped the SUV immediately. SUV lost DRIVE and began to roll back down the hill in reverse while still in gear (drive) and while pressure was still on the accelerator. RPM’s showed 4000. I hit the brakes and put in park; got out to see if anything fell off the engine but no sign of parts or fluid. Returned to SUV and put back into DRIVE and hit accelerator. RPM’s increased but SUV rolled backwards again. I pushed brake and put into LOW gear; hit accelerator and SUV continued to roll backwards while RPM’s increased. Pushed brake and put SUV into REVERSE, which did work. Drove in reverse with flashers on down the hill and
then spun around in reverse, and went back up in reverse (.3 miles to home).
Returned home and waited for tow-truck. When tow-truck arrived (45 minutes later) we put the SUV in DRIVE and noticed it worked once again. Was told by towing company to not take chances and have towed to Wilson Motors of Corvallis, Oregon.

Weather Conditions: Wet and raining / 55-60 degrees
Road Conditions: Smooth blacktop / steep uphill
SUV Conditions: During acceleration between 25-35 mph / after running at normal temp (10 min)

It really looks like a transmission issue. Like if a gear inside the transmission is randomly blocked and prevent randomly the transmission to move in forward motion. I'm pretty sure it's not a problem with center shaft. As long as you drive only at right lane on highways until the problem is diagnosed and repaired, you should be ok.
