    I own a 2000 GMC Sonoma with 160K. After driving for approximately 20 minutes at 65mph, the transmission drops out of overdrive and won't shift back UNLESS I turn the motor off and on then it shifts fine for another 15 to 20 minutes. Fluid level is good but I'm going to replace the filter and fluid this weekend.
