No Core Required!
Price includes shipping to USA Lower 48.
This bracket holds the transmission wiring harness securely to the rear of the transmission. In some cases, like here in the Mid-Atlantic, they are rusted away or broken.
We custom make brand-new ones made of thicker steel that will last longer. They are shipped flat and unpainted, so you will have to bend, prime, and paint them.
This is for E4OD only, and only one needs to be ordered per transmission.
See the video link below on how to bend it to fit.

L/R Planet Carrier Core Required!
Price includes return shipping to USA Lower 48.
Perfect for the DIYer, this is a service to machine your L/R planet carrier for one needle roller thrust bearing on each side and includes two brand-new bearings. The two metal thrust washers between the Planet Carrier and the Ring Gear Hub and Shell will no longer be needed.
There is no core charge as your core is required up front. While this service is offered for both E4OD and 4R100, there are several different carriers that you could have as shown in the video. The service is the same regardless of which carrier you have.
There is no option to buy steel carriers here.
We do not sell cores, we only provide the machining service and the new bearings for the cores you send in. Bearings will be either Koyo brand, or OE for any of the Big Three truck makers.
See the video link below for detailed information.

No Core Required!
Price includes shipping to USA Lower 48.
Perfect for the DIYer, this is a custom sized Line Pressure Modulator valve for those who feel 0.372" is not enough and 0.427" is too much. Pair this with your favorite arrangement of aftermarket springs and shims for the perfect shift feel you've been looking for.
For this initial batch, we are making brand new plungers from high quality steel. For the sleeve, we are reclaiming worn out OE sleeves that have been rebored to fit these larger plungers and also cut them for o-ring sealing. If there is enough demand, future batches will be 100% made from scratch. Regardless, no core is required
Fits all 4r100 and all E4OD accumulator bodies.

Forward Planet Hub and Carrier Cores Required!
Price includes shipping to USA Lower 48
Perfect for the DIYer, this is a service to machine your Fwd Hub for one needle roller bearing and includes a brand-new bearing. The three-tab thrust washer between the Fwd Hub and Fwd Drum will no longer be needed. This mod also includes the addition of a bushing to protect the planet carrier and hub from wearing each other and tightens the subassembly up.
NOTE: This needle bearing interfaces between the Fwd Hub and the Fwd Drum. Anytime the Fwd pack is applied (all forward gears), there is no relative motion between the hub and drum, therefore, the bearing will not be in motion the majority of the time. The needle bearing portion of this modification is more for adjusting geartrain stack-ups and meshing than it is performance, however, some people want bearings everywhere so I'm offering it.
There is no core charge as your core is required up front. While this service is offered for both E4OD and 4R100, there are two different carrier/hub assemblies that you could have, so it is best to see which actual style you have before ordering.
We do not sell cores, we only provide the machining service and the new bearings for the cores you send in. Bearings will be either Koyo brand, or OE for any of the Big Three truck makers.
