auto trans problem

[mike0179]

Hi eveyone,

I just bought a 03 awd matrix with 58k and i noticed a problem with the auto transmission. when driving around 35 to 40 mph i hear and feel a slight vibration, if I push on the gas a little more it will shift down and acellerate like it should.
also, i noticed that when i approach a hill at a constant speed the trans will do the same vibration for second before it shifts down. I think it may be at the same speed as well because i dont notice it on hills above 50. it shifts and drives smooth otherwise.

thanks for the help,

mike

I'm experiencing similar problems with my 07 Tacoma, getting the run around from the dealership. Mine feels like driving on those small speed bumps vibration.
