1940 olds info needed

[Guest craiglwebb]

Hello, I purchase a 1940 olds with a hydramatic tranmission. Where and how do you check the fluid level. What fluid do I use? Thanks.

1940 Oldsmobile Manuals is the site for the shop manual for your car. It should help you.

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 Guide

Unfortunately, they did not seperate it like the did the other.

Good luck with your car!

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.
