Toyota Dyna Transmission

Dyna gearboxes are the second-most-requested drivetrain component after engines, and both depots hold toyota dyna transmission stock across every SA-market series. The bulk of our inventory is the 5-speed manual behind the 14B and 15B diesels — bombproof units that usually only come off donors when the chassis or cab is written off. We also carry the overdrive-equipped gearboxes from the 6-series, the heavier-duty units behind the 7-105 and 7-145, and the rare automatic options fitted to a handful of later 8-145 closed-body and refrigerated trucks.

Dyna transfer cases are not common since the majority of SA Dynas are 4x2, but we do hold 4x4 transfer cases and front-axle assemblies for the limited-production 4x4 variants used by farming and mining operators. Diffs are sold assembled by ratio, so quote your truck's final-drive code or VIN. Clutches for the 14B and 15B Dynas are commonly replaced consumables — we stock heavy-duty truck-spec clutch kits new (R3,800-R7,500) and used pressure plates and release bearings from CPT donors. Propshafts (with and without centre bearings) are available as matched pairs from the same donor whenever possible.
