Soooo close, or maybe not, actually driving this thing. The last item is getting a shifting down. I put a new coupler on a shifter that Bruce made sure was correct in its dimensions.
Good coupler and bushings, firewall bushing a bit marginal, console one is fine. Come screws all aligned and tight. Clutch cable adjusted properly. Clutch pedal actuating properly. Aligned the shifter to rod per instructions and per the last two I’ve done. Can’t get a clean shift with the car running, getting a grind in every gear. Car not running and clutch in and it’s physically hard to move the lever into gear.. Drained the oil and it was used but not terrible, no water or foreign matter. That suggested to me that I need to drop the transmission since the clutch or pressure plate is an issue? Anyone with other ideas? Thanks! |

Hi guys - thanks for the ideas.
To be clear - I haven't driven this because I can't get clean shifts. When I get close to going into a gear I can feel the teeth about to make expensive sounds so I back off. @eric914 - no clearance issues on the bar, good thought but I checked. Good idea(s) on checking the clutch tube to make sure it isn't moving. When I manage to get the car into a gear when the engine is off it will start to move with the starter. Shifter is loosening up, which I think is the internals of the gearbox loosing up after sitting actually, feels like the sliders are starting to move more freely. Agree that the clutch isn't engaging properly - more diagnosis tomorrow. Thanks again! @nacho - smarter driver wouldn't have bought this in the first place. Grin. |

When I manage to get the car into a gear when the engine is off it will start to move with the starter. So what you're saying is with the clutch fully in there is still power transmission from the engine to the rear drive? Grinding in all gears and the above characteristic is the clutch not completely disengaging. Not sure why but the clutch is still engaged a bit which would causing grinding in every gear since there is still torque on the main power shaft when trying to shift. |
