When I get on the interstate I get on it pretty good to get up to speed and the truck dose fine until I get over 55 it will feel like it goes into nutrual and I'll let off and it goes good after that need help normal driving it shifts through all gear good I replaced transducer and didn't replace control selinoid I should have need help asap

 

Might be your overdrive or lockup acting up. Hit the OD button to see what happens. It will still lock up with the OD off.

 

When I hit the overdrive button and I gas it it dose it still

 

How many miles on it? When was the last time the bands were adjusted?

 

180 and they just got ajusted new fluid and filter

 

Was it doing the same thing before the adjustment?

 

Yes it was I'm stumped on this

 

Check the fluid level first, and see what the fluid looks like. Did you find anything interesting in the pan on the last fluid/filter change?
