Important Guidelines
To improve transmission longevity and preserve the warranty, please follow these guidelines when installing and running your new transmission:
Oil Cooler
For transmissions that use an oil cooler, it is important to have it serviced or buy a new one (and flush the oil lines). If there had ever been water, metal particles, or other debris in the old transmission oil, or the old transmission failed or was slipping, reusing an old oil cooler can cause debris to enter the new transmission through the cooler circuit, which can void the warranty and lead to premature failure.
If you need a new oil cooler, you can view a list of coolers here. The oil cooler used by the transmission will vary depending on the engine make and model, so yours may not be listed. Contact for help if needed.
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. If you need a new damper, you can view a list of dampers here.
If you're changing from a Volvo MS-series transmission to a ZF, you'll also need to switch from the original spring type to a Centa bushing type damper.
