Hi, I have a 2006 V50 auto trans with about 190000 mles. It's been a great car till recently. Driving down the highway about 75mph and suddenly no power to the wheels, step on the gas and it just revs the tach up. The car coasted forever as if there was no torque converter anymore. I got it towed home and chkd the fluid, a real **** on this car, and it was fine. Chkd the cv axle on the drivers side and it didn't appear to be pulled out but in gear it did appear to shimmy a bit. Shifting gears while running drops the tack about 1 tic, putting it in park grinds the gears. There was no dramatic sound or feeling when this happened. Any ideas?? Thx.

 

The grinding noise is the parking pawl. You are trying to put the car in park while it is moving, except it's not moving. Meaning the transmission is still spinning - I'd bet one of your axles has pulled out of the splines in the transmission. Do you have an aftermarket right axle installed? If so the center bearing on those can "walk" down the axle and pull the splines out. The axle looks installed - but it's not because the bearing is in the wrong place. Tap bearing back into place, stake it into place onto the axle, and drive away happy. (if that's the problem)

 

U nailed Hoonk. Finally got the car jacked up today and the shaft is pulled out. Looks like the bearing is toast. There are a couple seals running up and down the axle to the tranny and a couple more scrunched up between the bearing and joint. No fixin this one. It was replaced a couple yrs ago. Looks like these aftermarkets are crap. Thx for the help Hoonk.

 

Go with GKN when you replace it. OE replacement or (very expensive) volvo part is the way to go on the CVs.

 

I've also had good luck with Cardone rebuilt (OEM) axles. They cost a little more than the new Chinese axles (including those that Cardone sells), but that should clue you in on the build quality of those new axles!
