My 94 740i was driving fine, up until yesterday. I started her up put it in drive and took my foot off the brake and nothing. If I put my foot all the way down on the gas the car will budge, but just barely. I'm wondering if it's the transmission, or torque or even the brake switch. FYI it reverses normally- all drives do not work.

Sounds like the tranny.

I don't think so, as it goes into reverse normally, also there was no prior indication of a problem. But I'll look into it- Any other suggestions??

Maybe it is just in the linkage

Clutch packs likely need replacing; i.e. complete transmission rebuild.
