Andy J Posted January 25, 2023 Share Posted January 25, 2023 Can MD-3 transmission fluid be used in the hydramatic? I'm ready to fire up my rebuilt '51 straight eight with rebuilt hydramatic transmission.A friend gave me a case of Chevron MD-3 fluid and I intend to use this if it safe for the hydramatic. What do you fellows think? Link to comment Share on other sites More sharing options...
PONTIAC1953 Posted January 28, 2023 Share Posted January 28, 2023 I read that the GM license for the ATF name Dexron III expired on 01/01/2007, the new name of MD-3 replaces Dexron III. Link to comment Share on other sites More sharing options...
Andy J Posted January 28, 2023 Author Share Posted January 28, 2023 So It should be safe to use this MD-3 in my hydramatic?It was given to me to save a few bucks,but if it's questionable I'll get whatever I need.Thank you for your reply. Link to comment Share on other sites More sharing options...
OrtonvilleBob Posted January 28, 2023 Share Posted January 28, 2023 Better than just safe, it's a good choice. Chevron is an excellent brand. As Pontiac1953 pointed out the Dexron III transmission fluid designation for our vintage hydramatic transmissions is obsolete. The new designation is MD-3. You got great deal.

PhilAndrews Posted August 10, 2023 Share Posted August 10, 2023 It's good oil, but it might be a bit light for summer. Try it and see. Phil Link to comment Share on other sites More sharing options...
