C6 grinds in first - 1980 F-250 - C6 with shift kit. Was sitting all winter. Terrible grinding noise and no power. Engine doesn' t want to idle either. Thought it was the rearend. Took it apart looked ok, changed fluid..still grinding. Noticed that the grinding stopped when shift out of 1st. Is there a quick fix, maybe Lucas transmission additive.

peugeot 407 v6 3.0 very short-time rattling(grinding) noise at cold-start, source ... but a friend told me it can be anything else as well (like those solenoids)! ... C6 makes when starting cold - is that a VVT or a valve lifter noise?.
See if it the torque converter making the noise. Ford had these converters take would make like a rattle/clicking noise. Not sure if they went back that far though. The noise doesn't hurt anything. Every thing still works fine. It was just annoying.
You must have a manual transmission. Rebuild it. synchronizers are bad. The reason for grinding. Then you have worn shift forks. Reason for popping out of gear. Also replace any worn bearings or just get the bearing kit and replace them all, with the races.
Ford C6 Verify there is vacuum to modulator, the rubber line tends to break/falloff Verify the kick-down cable is correct Verify the linkage is correctly adjusted. A C6 reads engine vacuum and throttle position to automatically shift
From 1990-1996 The C6 was replaced by the E4OD which was modified to include a fourth forward speed and electronic shift controls, replacing the hydraulic control mechanism of the C6.
The C6 works fine in your bronco.. Your friend will need a different transfer case!. i dont have the manual but this is my best guess. FOrd likes to make cars that have interchangeable parts. Like a 1999focus can interchange with 2007. as long as the liter and engine size are the same. In some cases. you will have to use different transfercase.
So you might be better off with a c6 transfer case or c4 for your friend.
