The OP wrote “I have purchased an overdrive transmission“, though he didn’t give any details about it. His knowledge level of his truck including the torque tube may be... limited. For a long time I didn’t really understand them either. Hopefully he’s reading and learning from here and other sources.
Hi guys. Sorry for the delay getting back and thanks for all the informative comments.
As with many this past year was full of challenges that pushed the truck down the list of things to take care of. Well we're back on steady ground and looking to get things running with my 3100.
To answer some of the questions I have replaced the torque tube driveline with an open rear axle from a 1955 3100. I adapted it to the original leaf springs to get the correct ride height and wheelbase. I replaced the original 3 speed transmission with an gm overdrive transmission from that period. Looks similar to the original trans but has a solenoid and cable that run to it to control from the driver seat I don't plan on installing the full automated system but use the cable to engage / disengage the overdrive.
The last part of the set up is getting a drive shaft to tie it all together. The tail shaft on the trans is 16 spline. Need to find a source for the new driveshaft. Any thoughts? I hear the discussion on the front chassis and brakes. The original have worked fine previously, but I think an update from the single master cylinder would be a good modification along with the roller bearings instead of the ball bearings.
Look forward to the next round of advice. Thanks in advance.
There should be any number of driveshaft makers up your way. I'd try to look closer to home to minimize shipping costs. If you need help on measuring for a new one, please let us know. Not difficult at all.
Mr Masseyman You'll learn this,with the overdrive in the truck can roll away. Best to park in reverse which will take it out of overdrive !! I also put my kickdown on the dash ,so I didn't have to throw the throttle wide-open to downshift.
55-57 Passenger cars and 3100 TF trucks with a 3 speed or OD trans use the same driveshaft. I believe the earlier models like your truck have the same wheelbase. If so, find one for those years and you don't have to make one up.
