hello,

i have no tach in the van. maybe buy a cheap obd tach to see what I'm running?
i know its a van but mileage is sub optimal. 60k miles. new plugs/tires/chocks/tie rods/oil etc.
at highway speed (65) the RPMs seem pretty high around 2500-3000. overdrive button doesn't do anything, doesn't light up.
is this normal sound range? other than that. the van is like new. picked up it a month ago.

thanks

 

Overdrive button doesn't lite up until you turn it off. Then it will say OFF.

 

so it could be stuck on. that wouldnt explain the higher rpms then. thanks

 

The electrical part of the system may be working , but the overdrive parts in the trans may not be responding.
If the trans pan was dropped , you might be able to see something like a lock ring that came out allowing the overdrive piston not to work and maybe just sitting in the bottom of the pan..
