The new adaptor housing has been completely redesigned from the ground up. The cast aluminium housing is fully CNC machined and incorporates additional webbing which allows our heavy duty alloy TH400 sump/oil pan to be bolted directly to it's front face.
The alloy sump/oil pan has a number of features which make it ideal for competition applications. Firstly the sump/oil pan is very heavy duty, it has a rear mounting face which has one flat surface and three heavy webs that attach it to the main body of the sump/oil pan. This rear mounting face is bolted to the face of the adaptor housing, by doing so it is more than doubling the strength of the back of the TH400 main casing.
The sump/oil pan also has a mounting face which allows a large transmission mounting rubber to be fitted in addition to the original Nissan transmission mounting. This allows you to fabricate an additional cross-member support directly under the TH400. The combination of two transmission mounts being fitted will also help to reduce the heavy up and down stresses being applied to the lightweight TH400 bell housing.
The right hand side of the sump/oil pan has been shaped for additional front drive shaft clearance. The oil pan is also equipped with a drain plug for ease of servicing.
The TH400 has an overall case length of 616 mm. When coupled to our 134 mm adaptor housing gives you an overall transmission length of 750 mm.
