David J D Todd Posted August 11, 2019 Share Posted August 11, 2019 Hello and help please. I am in South Australia and need some advice. I have a 1952 Pontiac Chieftain coupe 4.4 litre straight 8 with the 4 speed dual ratio automatic transmission. I have just finished a total off chassis restoration and have a problem with the transmission. I can drive the car up to 30 miles with it performing beautifully then all of a sudden I have no gears. It will not shift into any gear. I have checked the trans fluid level and that is okay. Is it possible that the torque converter could be causing the problem? I just don't have any answers. This has happened twice and it is a real puzzle. Can anyone please be able to help me with this problem? Thanks, David Todd Link to comment Share on other sites More sharing options...
EmTee Posted August 12, 2019 Share Posted August 12, 2019 Was the transmission overhauled as part of the restoration or was it just set aside? How does the fluid look? Is it clean (pink/red), or dark-ish? Link to comment Share on other sites More sharing options...
PhilAndrews Posted August 19, 2019 Share Posted August 19, 2019 When it quits giving drive, if you engage reverse does it lock up the transmission as if you had parked up with it switched off? Is the oil level too high? When it's hot it may be getting caught up in the drums and getting whipped to a froth and your losing oil pressure as a result.. pull the dipstick when it stops and look too see if the oil is all bubbles.
