Trans issue

02 tundra base model, 200014 miles truck shifts fine at low thottle. Under load tack high shifts hard. Also has no power under hard accleration. No enegine light no codes.. im thinking torque converter and possible shift selinoids

 

Fluid level look good once warmed up?

 

Yes fluid lvl.is good

 

I did water pump and timing belt at 136k starter at170k alt at 176k other than that the truck has been fine fuel.pump at around 150k

 

Wouldn't be the 1st torque converter 'round these parts...

 

Probly not for for either if i had been first owner. I had it a couple months before the water pump. I just put rotors caliper and brakes on it . Drilled vented slotted rotors 4 piston calipers and ceramic brakes bc i drive it hard and that little v6 has been a trooper

 

I know this isn't the first or a popular option. You could always take it to the dealership and cough up around $130 for them to run a full diagnostic on your transmission. Ideally if you can find a highly reputable transmission shop that's the route I'd go once I run out of ideas.
