I have a 2005 Acura RL and I'm having shifting problems where the end transmission vibrates feels around 32 _50 km an hour it does anybody have an idea what this could be could this be an actual transmission problem do I need to replace the transmission I have the oil and it still seems to do the same thing

 

Have you had your mounts inspected? How many miles on the car?

 

My 04 MDX had this. What cured it was three quarts of oem trans fluid changed 3 times in succession over three days.
