With our new tool that locates a lube hole directly feeding the C-3 clutch & patented PTO cover, you can get the much needed lube oil to the Allison C-3 clutches. The new PTO cover funnels oil to a hole in the trans case that supplies lube oil directly to the C-3 clutches. This oil would otherwise return to the trans pan unused. We have now directed it to the C-3 clutch pack to lube & cool this hard working clutch. We have created a jig tool to insure proper hole location when installing the Goerend PTO covers for the Allison 1000 and 2000 units. This upgrade must be done with the transmission out of the truck and empty - do not perform this upgrade unless the trans is disassembled. There is an $50.00 Refundable Core Charge Fee on Goerend Jig Tool to install covers. Use a ¼" drill bit with PTO jig tool. After you use the jig tool, please send it back to Goerend Transmission for your $50 refund. Jig tool refund amount will be based on condition once it is returned.
Don't have them installed yet, they look nice and very high quality. The only thing I would suggest is some nice stainless steel bolts to go with them.
