Protect your US Shift Transmission Control Module from the elements with this water resistant enclosure, modified in-house at Black Dog Customs specifically for use with our HMMWV 4L80e transmission harness kits.
Each box is custom modified at our shop. We cut a precision opening for your transmission harness wires to pass through and include a sealing plate that installs around the wiring. For maximum water resistance, apply silicone around the sealing plate after installation (silicone not included). This gives your TCM a solid layer of protection from mud, water, and the general abuse a HMMWV is built to take.
This enclosure is designed to work with all three Black Dog Customs 4L80e standalone transmission harness kits:
- 6.5L Turbo Diesel 4L80e Stand-alone Wire Harness & TCM

What’s Included:
- BDC-modified water resistant TCM enclosure

Installation Note: Silicone sealant should be applied around the sealing plate after installation for optimal water resistance. Silicone not included.
