Parts for the

T18 & T19 Transmissions

The T18 is fully supported for parts. The transmission remains in aftermarket production at Novak and is still one of the most popular truck, industrial and Jeep conversion transmissions available.

The Master Rebuild Kit

Our master rebuild kits have been assembled for our customer's rebuilds as well as our own. It is the most complete kit we've seen anywhere and features all the consumable and wear item components.

Rebuild Requirements

It is common for our customers to do top-level rebuild work, using good methods and by following our included instruction guide.

We suggest the rebuilder have access to a set of snap ring pliers, a bearing puller and a hydraulic press.

Other Components

Because we manufacture new T18 assemblies at Novak, essentially all parts for the T18, including gears, shafts, factory adapters & tailhousings, retainers, etc. are available. For anything not shown, contact us.

This is the rigid PTO cover that every Novak-built transmission gets, and we recommend them to our customers. They seal better and stay that way for far longer than the stamped steel versions from the factory. Stainless button-head fasteners are included.
