Change Transmission Fluid and Filter
(Initial)
Change transmission fluid and filter (2) after first
50 hours of operation. Change more frequently if
working in dusty conditions.
To change:
1. While fluid is warm, remove drain plug (3),
screen, and filter (2).
2. Drain fluid and reinstall plug, screen, and new
filter.
3. Add approximately 6 qt (5.6 L) of PTF at fill
(1).
4. Start engine and run at low idle with transmission in neutral.
5. Cycle transmission from forward to reverse several times.
6. Check fluid level at dipstick. Add PTF as necessary to keep fluid at the appropriate line on the dipstick
according to the table below.
Oil temperature Condition Line on dipstick
50-86°F (10-30°C) engine at low idle a few minutes after startup COLD
176-212°F (80-100°C) normal operating temperature HOT
IMPORTANT: If transmission fluid temperature falls between the two ranges listed, fluid level should fall
proportionally between the COLD and HOT lines on the dipstick.
NOTICE:
• Transmission damage can occur if oil is not maintained to the correct level.
• Use only Ditch Witch-approved Phillips 66 Torque Fluid transmission fluid. Do not substitute any
other transmission fluid.
