Automatic transmission problems
Although I've titled this automatic transmission, the problem may be elsewhere. My car is a Volvo 1997 V70 wagon 2.4 DOHC Engine B5254S.
Recently replaced timing belt, tensioner, auxiliary belt, water pump, camshaft seals and resealed upper cylinder block.
Here's my issue.
On Sunday March 12 while rounding the roundabout I gently accelerated when I heard a clunk and the car rolled to a stop. Engine still running but no movement. Tried selecting reverse and drive and got nothing. When I tried to move from Reverse to Park there was a grinding noise, like gears meshing. Noise stopped once Park was selected, however the Park function did not work as I could push the car.
Had the car trucked home and did the following:
1/ Jacked up front wheels on stands. Turned RH wheel by hand and LH wheel would turn in reverse - also did same with LH wheel. This was while drive selector was in Park.
2/ Checked under car for disconnected axles etc - everything looked ok.
3/ Checked that drive selector actually moved the selector on the transmission. No broken or loose cables.
4/ Started engine and engaged Reverse. Both front wheel spun backwards.
5/ Lowered car to ground and did a few drives up and down the driveway. All seemed ok.
6/ Took car for road test - drove around neighbourhood, over speed humps, sharp left and right turns, rapid acceleration and deceleration. No problems.
7/ Took car to church meeting March 16 (about 5Km). On the way home as I tried to accelerate out of a corner (LH) the same problem occurred. No clunk this time just rolled to a stop. No Drive or Reverse when selected and same grinding noise when going from Reverse to Park. Park not engaging.
Had car trucked home again. Next morning jacked up the RH (driver) side of the car and placed on stand. Wheel could be freely turned by hand even though Park was selected.
Decided to try something else. Turned on engine and engaged Reverse. When I did there was a grinding noise for about 20 seconds then just normal engine noise.
Stopped engine, lowered car to ground and voila I now can select Reverse and Drive. Only doing this up and down the driveway. Don't want to call the tow truck for a third time.
Hope someone can assist me with this very unusual issue.
