have a 99 AWD wagon with 2.5 & auto tranny. have engine vibration which seems to occurr during eccelleration maybe after 1800rpm. replaced axle on driver's side with used axle/knuckle a while back when wheel bearing had failed. that assembly appears to be tight per my mechanic friend. he thinks it is a tranny issue. engine vibrates when car is on jacks. vehicle did not move foward one time but was ok after putting it in reverse. any ideas how to isolate the problem or fix it? have checked the drive shaft and it seems to be OK.

Bad vibration under load and vehicle would not move foward one time recently. Auto AWD. Car's in nice shape but don't think i can take the time to change tranny. Knowledge lacking as well. Any thoughts on repair or value?
