Before you open the transmission
A lock plate holds the reverse idler shaft and countershaft in place, so its role is simple but important. When it wears or cracks, the shafts can move out of position, and reverse may engage poorly or grind. Because the plate sits inside the transmission, most owners have the work done by a shop, and the job is easier when the case is already open for other repairs.
Before disassembly, photograph the original plate and note how it sits against the case. Compare the new plate’s bolt holes and shaft bores with the old one, and clean the mating surfaces thoroughly. Bearings and gears are often inspected at the same time, since they see the same wear.
- Check bore wear and any cracks in the old plate
- Clean the case surface before fitting the new plate
- Inspect reverse idler gear teeth while the transmission is open

Installation notes
Reaching the reverse idler shaft and countershaft on a T14 means opening the transmission, so this job suits an experienced transmission technician.
What’s included
