Getting ready for a 3300 mile round trip in the old first gen. I change the oil in the Getrag today. Only about 1 quart of fluid came out of it. I put in 4 quarts of 5w20 synthetic plus 1 quart of Lucas Full synthetic oil additive. It's amazing what the proper amount of fluid will do to quiet things down. That is all. Just an observation.
yea when mine went out it had no oil in it..probably had none in it for a year. towing a camper one day and it came to a sudden stop in the middle of the road. i hear some people use thin tractor hydraulic fluid take off the top plate and over fill the tranny
I take out the shifter and put in 5 qts of 15w40 every year, or 30k.
