454 one ton trans problem

Hi all, I have a 1993 motorhome with a 454 and an automatic 4 speed overdrive trans. After driving a couple miles it comes out of over drive and will not change back unless I turn it off for a few min.

Wonder what is going on here?

Thanks,

Troy

Sounds like a loss of pressure once she's heated up.

Post in alt.autos.4x4.chevy-trucks, there are a few trans specialists there that could probably help.
