Damper Plate
Also called a drive plate, this bolts to the flywheel and engages the transmission input splines.
It dampens the engine torsional firing impulses to protect the transmission.
An old, damaged, or worn out damper plate may not dampen the torsionals as well, leading to premature wear and tear, or in the worst case a complete failure.

Oil Changes & Fluid Types
Check your transmission oil fluid level regularly and change it following the owner's manual guidelines.
Never go more than a year between oil changes.
If you aren't sure what oil type to use, here are recommendations:
For ZF 12, 15, 25, 30, 45, 63, 68, 80, and 85 series, and Velvet Drive 71C, 72C, 73C, and 5000 series, use an ATF fluid which meets Detroit Diesel Allison C-4 specifications (e.g.: Dexron IIE, Dexron III).
For ZF 220 and larger series, use a marine 30W transmission oil (no/low detergent, not multi-grade).
In very hot climates 40W is okay.
