I was looking for some general trailer information for my daughter and stumbled on to this Ford chassis stuff,

Ron Pung, Ford Customer Service, Modified Vehicle Specialist, presented a seminar on maintaining the Ford Class "A" and Class "C" chassis.
Here are my notes from that seminar:
2002 and after, there are no U-Joint grease fittings.
Using 5w20 instead of 5w30 will give you 1/2 of 1% better gas mileage.
The special tool to remove the fuel filter is NAPA / K&D part # 3321 for a 5/16" gas line.
The latest fix for the water ingestion problem is TSB 04-24-22 and is available for those chassis with this problem even out of warranty.
Normal automatic transmission fluid temperatures should be 170 to no more than 220 degrees under heavy loads and when using the transmission for braking.
The Hydromax brake systems after 2004 use DOT 4 brake fluid. It's okay to retrofit your DOT 3 fluid with the DOT 4 fluid with a good flushing.
The V-10 was never designed to use 7 quarts of oil. Use only 6 quarts with a filter change every 3000 miles regardless of the type of oil used (don't extend oil changes when using synthetic oil).
The old "T" handle dipstick is 1/2" too short and makes it appear more oil is needed to bring the oil mark up to full. TSB 01-10-5 replaces the dipstick with the "LOOP" handle model. Excess oil consumption is more than one quart in 1500 miles.
To rotate tires, keep them on the same axle and swap sides.
The Cruise Control switch problem which caused fires in other model Ford products does NOT effect the motorhome chassis.
The V-10 is speed limited to 83-85 mph through 2003. In 2004 it is limited to 75 mph to match the max speed of the tires.
The V-10 is limited to 5400 rpm by the computer.
Max HP is achieved at 4200 rpm through the 2005 model year. In 2006 it is 4750 rpm with the higher HP engine.
The oil leaving the transmission and going to the cooler is in the line near the front of the transmission.
A remote filter for the transmission has been added for 2006 and is a recommended upgrade for prior models as is a transmission temperature gauge.
"X" in the 9th position of your VIN indicates you have a 1999 275 hp V-10. "Y" indicates a 2000 chassis with the 310 hp V-10. "1" indicates a 2001 and "2" indicates a 2002 and so on...
The Banks TransCommand is a good upgrade if you don't mind the slightly firmer shifts. It reduces slippage during shift by increasing the pressure inside the transmission.
