Hello all proud owners of Toyota vehicles, I have my Camry since February this year, it runs beautiful, up until about 6 weeks ago, 5th gear would automatically slip out when i let go of the accelerator, long drives on the freeway wasn't so bad, as i would always have my foot on the accelerator, but for about 6 weeks now, as soon as i place the gear in 5th, and release the clutch, it slips out, so i now need to hold it in gear. Any suggestions of what the repair might consist of?
