Oiwa Garage Tech Note
"Support the transmission on a jack before unbolting the mount. A collapsed transmission mount clunks on every shift - fresh mounts settle the driveline."
Frequently Asked Questions
Should I do the engine mounts too?
If they are the same age, yes. Mounts wear together, so a full set keeps the driveline settled.
How do I test the transmission mount?
With the brake on, ease the truck against the driveline in gear and watch the mount; a clunk on take-up and cracked or collapsed rubber mean it is due.
How do I support the gearbox to swap it?
Support the transmission on a jack before you unbolt the mount, lift just enough to free it, and fit the new mount before lowering it back down.
