Hi all so I had previously made a post about a 41 chevy sedan I acquired. I thought the engine was stuck, long story short this engine was rebuilt and the car stored for about 20 years indoors. I took the head off and the cylinders look great. I do not see a spec of rust and can still see the cross hatch of the cylinders. I'm thinking that the transmission is stuck and that is causing my issue. It will shift but locks up periodically and does not ever feel like it really pops out of gear. I have laid a cinder block on the clutch and attempted to turn the engine with no avail. I've also jacked up the rear of the car and attempted to turn, however the rear drums are locked up. Should I pull the transmission? If so any good videos out there showing this? I'm young and never had anyone show me how to work on these old cars so explain it to me like I'm ten. I appreciate all the help from those with experience here. Thank you
Hi, I'd work on the brakes first, then look at the clutch. The transmission itself might be locked up if the shift linkage is wonky, but any part with friction and iron (brake shoes and drums, clutch lining and flywheel and pressure plate, for example) is more likely to be locked up from corrosion.
I’ve seen the discs stuck to flywheels. Somebody pressing the clutch pedal while you are underneath with a thin scraper between the disc and flywheel to in stick it. Sometimes you may need light hammer taps to get the scraper in there.
Is there anyway to slide the transmission out without having to release the rear end to push the torque tube out?
I’m not sure about the 1941 torque tube but ‘49 - ‘54 you undo the 4 bolts at the back of the ball at the rear of the transmission, slide the ball back along the torque tube. This exposes the universal joint which has 2 caps that can be unbolted (there are clips that hold the bolts from turning, they have to be folded back), slide the caps off then the torque tube can drop down out of the way. I think I remember having to drop an arm for emergency brake out of the way. ‘49 - ‘54 transmission comes out from inside the car, a cover is removed from the transmission hump and the transmission slides back an up out of the hole in the hump. It’s been a long time since I’ve done this and my apologies if the ‘41 is different. Try to find a manual.
First thing I would do is disconnect the shift rods at the transmission. Then move each lever forward and back to find the center position. You are now in neutral. See if it's still stuck. If still stuck, remove the belts incase the water pump or generator is stuck. If that doesn't work, remove the starter in case it is jammed into the flywheel. By the way, how did you determine that the engine is stuck in the first place?
Dave Downs described it perfectly. In a pickup of the same era I used a jack under the torque tube to slide the transmission back and out the top.
