Any chance my transmission isn\'t dead? My '71 had been sitting for a few weeks, so I hopped in yesterday for a little spin around the block. I put her in drive, mashed the gas and started moving forward. Once the engine revved to the point it should've shifted into 2nd, it didn't. I let off the gas, then mashed again--this time nothing, no forward progress whatsoever. So here's my situation, I still have reverse, but no forward. Any chance the transmission (TH350) isn't terminal? Could there be a simple fix, or am I looking at a costly rebuild? Thanks.
