Default Tranny not shifting into Overdrive??

Hey guys!

Seems like my truck is not shifting into overdrive. When I am on the Highway and running about 70mph I am turning about 3000 rpms. The O/D OFF light also starts flashing. What would cause this and what can I do to fix it???

Default Re: Tranny not shifting into Overdrive??

Have you taken it to a trans shop to have the code read?

If you press the O/D Off switch, do you feel the transmission kick out of overdrive, or notice an RPM fluctuation?

It could be a few things. The code will tell you in which circuit that the code resides, and will allow for a better diagnosis of the problem.
