First guess would be misadjusted coupler at the front of the trans (the one under the tunnel plate just behind the seats).
There are several good threads on how to adjust it. Bob

Right - or the bushings in the coupler are worn too much. Same place to look. Go on the 911 forum for 915 advice, of which there is plenty. Look for "coupler."

HI daveg74
it is a 915 box 1974??? if so check the bushes under the gear lever also, for wear, as a small amount under there is a large amount in the box, is there any noise from the box when shifting? regards mike |

Take a look at the following 2 links:
Pelican Technical Article: Shifting Improvements - 911 (1965-86) - 930 Turbo (1975-86) Pelican Technical Article: 911 Shifting Improvements This should help you isolate the issue to some degree. |
