HOW TO Rebuild a Toyota W56 Manual Transmission!! Complete tear down and disassembly, removing shift forks, bearings, gears, synchro rings, detent balls, interlocks, snap rings, springs, and synchro/clutch hubs. By the time we're finished we'll be left with the bare cluster shaft, main shaft, and mid plate. A deep dive into how these transmissions work and how to fix them.

This W56 5 Speed transmission is out of my 1986 1st Gen 4Runner, and it had an input bearing failure which sent metal shavings throughout the cases and warranted a complete rebuild. These old Toyotas are known to be rock solid reliable and this transmission is no exception. It survived over 300,000 miles and I drove it home with the bad bearings without breaking a sweat. It was my first time taking one of these things apart, and I have to say it went pretty well! All I needed was a couple of bearing pullers, assorted wrenches and sockets, snap ring pliers, and patience! I think you can keep costs low and learn how to repair your own vehicle by taking on a project like this.

The W56 was found in the Toyota 4Runner and Pickup from 1985 1995, both 2WD and 4WD models. Should also apply (mostly) to other WSeries Toyota Transmissions including W55, W56A, W56B, W56C, W56D, W56E, W57, W58, and W59. This transmission is found in the Toyota Pickup and 4Runner, but should also apply to later Tacoma and T100 models using the W59 and Celica, Cressida which also use a similar transmission.

Previously, I removed the transmission from the truck and removed the bellhousing, transfer case, and split the cases. That's when I found the blown input bearing and knew I had to take this thing apart and do a complete overhaul and restoration.
