  • Transmission I.D.

    I have three transmissions they all came out of trucks half and three quarter ton late 60's and one from a 71. I wanted to know how I idenify what they are. They all look the same. I am sure there are some numberson them to let me know what they are. I will steam wash them and find out what I have. Also what is the best oil to put in them in you guys opinion for heavy torque loads and I will only used in the hot summer heat. Is lucas oil a good decesion I have never used it?

    Sound like T98 manuals 6.4:1 granny first.

    I'd look into running Red Line Synthetic. The sell an improved 90W designed for high torque loads.

      I also like the Redline MT-90 and Amsoil products.

      I tow a 22 travel trailer with my Scout Traveler and run 80-140 Amsoil synthetic in the rear differential. Last summer a friend had a Lazar temperature gun and we compared temps. While he was towing nothing and I had the 22 travel trailer my temps were only 10 degrees higher than his, we both had the same gear ratio but I had 33's and he 35's. So my diff was spinning faster as well.

      The Redline MT-90 is also rated for transfer cases and manual transmissions but NOT differentials. They have other product for that.
