You have frozen water locking the bull gears to the housing. Heat the rear end and drain the water out. 15 gals. of Hy-Tran

I have had hytran equaivalent in my 300 transmission and hydraulics since I got it going in 2012 and it has been fine so far.

I have a picture of the additive can. This was the start of Hy-Tran, mixing with 10w oil and adding this additive. I remember as a kid at home there was a gallon can of additive setting on the shelf in the garage. I sure wish I had that can today. Hy-tran will be just find today.

Back 'in the day' there was no such thing as 'Hy-Tran'.It had not been invented yet.Hence the requirement for the 10wt/TA additive.Today HyTran or equivalent(JD Hygard;Transdralic fluid;303;Phillips HG fluid.......)is accepted for use.

I have some quarts Charlie. They are marked "IH special #61" Mix 1 qt with 5 gal.

That additive was retained later on to be used in steering gear boxes and it works very well. Very extreme pressure lube used straight. Wish I would have grabbed some years ago for my old H's and M.
