What causes the engine to stall when putting the transmission in reverse or forward?
The car is a 77 mercury comet with a 302V8. It appears to have a C4. The engine runs
fine when in park or neutral. When engaging the transmission at idle, it seems to be in
direct drive with no slip.
I'd check to see if the vacuum modulator was mis-adjusted or bad.
