Tom,
I found the drain and check plugs on the trans. I pulled the check plug slowly expecting a flood of fluid coming out. Instead I found nothing. I stuck my little finger in the hole and could not reach fluid. I added 2 gallons and I could finally reach the fluid with my finger but just barely. I started the loader and it drove 100% better. I'll get a couple more gallons of dextron and fill it up to the check hole.
I have to thank you for your help with this. I really appreciate the guidance. I'll be sure to keep an eye on the trans fluid from now on.
I don't know about 55's in particular. Just assuming the transmissions are like the 75 they are supposed to be checked at idle. If filled to check plug with engine off they will be very low on oil when running. The converter housing drains into the transmission when off. This is why the shifter rods leak much more when parked as the oil level rises. If this doesn't apply please ignore.
