bill pritchett Posted June 24, 2010 Share Posted June 24, 2010 1940 Oldsmobile Manuals is the site for the shop manual for your car. It should help you. Link to comment Share on other sites More sharing options...
Erndog Posted June 28, 2010 Share Posted June 28, 2010 I uploaded that manual to the site. They did a great job seperating the chapters for easy reference. You may be interested in another one I uploaded - 1940 Oldsmobile Motorist's Operating Guide. It is very hard to find, so here is the link: 1940 Oldsmobile Operating GuideUnfortunately, they did not seperate it like the did the other.Good luck with your car!

Guest Bob Call Posted June 30, 2010 Share Posted June 30, 2010 (edited) To check the fluid level the engine and trans should be at operating temp. Drive the car a little first to be sure the torus (fluid coupling) is full of fluid. If the fluid level is low some fluid will leak from the torus back to the trans as fuild always seeks it own level. Park the car and SET THE PARKING BRAKE and let the car idle in each gear for a few seconds to be sure there is fluid in all of the control body passages. Then put the trans in neutral and with the engine ideling pull the trans dipstick, wipe it clean, reinsert it all the way and then pull back out to check the fluid level on the dipstick.You should use a Dexron fluid like Castrol Dex/Merc. It is for all older GM auto trans. Ford trans use Type F. fluid. Edited June 30, 2010 by Bob Call (see edit history) Link to comment Share on other sites More sharing options...
