Driveline vibration I have a 2007 Ford Fusion AWD with 61,000 miles on it. It is a 6 speed automatic. Around 50-55 mph it has a pretty good vibration in the driveline. Sounds and feels like right in the center of the driveline.Anyone else had this problem ? Please let me know what causes this so I can correct it. Thanks.

a change of oil will be a big help
while the pan is off have the bands and clutch packs adjusted
Have the work done by an accredited specialist professional auto transmission shop
At this point there is no need for a replacement transmission

could be a cv joint problem
take it in to an accredited service center that handles your make of vehicle and have it properly diagnosed and a quote

the Ridgeline is powered by a transversely mounted J35A9, (2006-2008) J35Z5, (2009-present) 3.5 L V6 with a five speed automatic transmission. The all-wheel drive system operates in front-wheel drive mode under normal conditions and automatically transfers power to either rear wheel via a locking differential when it senses a loss of traction in the front. The VTM-4 system can be locked in first, second or reverse gears at speeds under 18 mph (29 km/h).
The VTM-4 lock (rear diff lock) works in full rear power mode up until 6 mph (9.7 km/h) then it gradually transitions to power to the front and releases the VTM-4 lock at 18 mph (29 km/h)

One thought would be to check if your tires are properly balanced. Try getting them balanced and then see if the problem exists.

It sounds to be a Constant Velocity Joint (CV JOINT)...You can look under the car at the ft.axles nd inspect the cv joint rubber boots...Normally they will split from wear or road debree and through the grease out making the bearings go bad...However some will go bad without the boot being torn...If that is the case it is best to replace the whole axle when determining which side it is.....Hope this helps..Check all components for looseness ...You really need to put it on a lift and check it.......Metalpoet

I need to replace the transmission in a 2005 mini cooper can I replace the 5 speed with a 6 speed?

possibly the transmission

Has the car even been in an accident? If so it could be a bent frame (worse case), Otherwise the car could be off balance and needing an alignment (Most likely - best case) :)

sounds like a cv joint to me. That is what usually occurs when one is showing wear. C.V joints usually wear out between 80,000 and 120,000 k.m.
