big jump from 4th to od/5th 2012 4x4

does anybody know why there is such a big jump from 4th gear to od on my 2012 4x4 v6 trd offroad ??
i have to get it up to about 80 to make it not bog if i have any load or am climbing a hill
i also have to drive around town in 4th instead of D or it feels like it is always in to high of a gear and feels underpowered
it makes me regret not getting the manual
any tips on trade in strategy??

 

What size tires are you running?
Should be smooth as silk and not displaying this issue... Take it in for warranty and have them check the fluid level, or do it yourself. Some have reported being underfilled from the factory. Good luck

See here for more info on checking fluid level...

I would use my warranty first though

 

it just had it's 5000 mile service but i just figured it was toyota going for high mpg numbers instead of useful hauling gearing
i'll take it in and have them check it out

thanx
