SO, this is probably a premature question until i replace my shift rod bushings... but in talking to Randal (who runs a rennshift), he mentioned he had occasionally had a similar issue:
when my car gets loaded down under threshold braking, making a 4-3 downshift becomes nearly impossible. the shift action 'wants' to go into 5th. forcing it over to the left (much farther than is necessary under normal conditions) will usually make it pop in with a bit of a grind. engine mounts (rubber) are good, tranny mounts (911-engine) are good, OEM shifter in good shape, firewall bushing okay, transmission-end shift-rod bushings a bit worn, but not at all decrepit. I hate going over the cyclone and grabbing 5th instead of 3rd... any suggestions? |
