not sure if this is normal for these trucks or not but since the summer heat has started to die down ive noticed that my yota wont shift into OD until it has completely warmed up. this isnt good on those days when im running late. if this isnt normal where should i start looking? truck is a 94 3vze w/ 140k miles and trans fluid looks good

 

this is perfectly normal on our trucks! no need to worry
