Elite Veteran Posts: 705 Location: California | Just got the engine sorted and running good. Trans was working fine then went to move the car yesterday morn. And right off neutral is drive, all gears are drive but the reverse push button locks it between 2 gears. The car will not roll when this is happening, locked up. Fluid is good. Checked all adjustments no idea what's going on. | ||

Elite Veteran Posts: 705 Location: California | Ran the cable adjustment from one end to the other and the only thing that changed it which button had to be pushed to activate the neutral safety switch. Then aet to factory specs. No change. | ||

Expert Posts: 3777 Location: NorCal | If the sprag had failed, there would be no forward movement in Drive but it would move forward in "1". I'm thinking there's something amiss in the shifter mechanism. Can you observe cable movement at the mechanism with each button push? | ||

Veteran Posts: 165 Location: christchurch New Zealand | I have the same issue with one of my 60 dodges, its internal unfortunately, have yet to remove the trans and pull apart,much as i wished it could have been a cable or shifter issue, a lot easier to remedy. Good luck | ||

Elite Veteran Posts: 705 Location: California | It's a nice 61 fury that a hillbilly got ahold of and have been undoing lots of stupidly done repairs. I know he had the trans out at one time. I'll drop the pan and see what's going on when the cable is moved. | ||

Elite Veteran Posts: 705 Location: California | Shift cable operating fine. Valve body is ok. Front clutch is dead. | ||

Board Moderator & Exner Expert 10K+ Posts: 13049 Location: Southern Sweden - Sturkö island | There are two possible reasons for the front clutch failure; - Piston seal broken/too hard, and/or - Sealing rings on the input shaft has worn out the bore with internal leakage as result That's a part from wrong fluid level which might also be a reason. | ||

Elite Veteran Posts: 705 Location: California | Thanks wizard. Applied air pressure to the front clutch port and nothing happened so the front clutch must be the issue. | ||

Board Moderator & Exner Expert 10K+ Posts: 13049 Location: Southern Sweden - Sturkö island | The internal leakage will "tell" by the leaking sound of the compressed air. If you hear no leakage and no "thump" it might mean that the front clutch is burned out by burn outs in the history of the car. | ||

Expert Posts: 3777 Location: NorCal | A front clutch that is locked up (seized) will cause the car to drive forward in Neutral and also lock up when in Reverse. This can be caused by the clutch piston over-traveling and popping out of its bore which jams the clutch pack. | ||
