I’m currently in the process of diagnosing an issue with my car’s transmission, specifically the inability to shift into 5th gear and reverse. Working on it yourself offers invaluable insights into the mechanical components, and a deeper connection with your vehicle.

The tools required for this job isn’t special. However, I highly recommend using a shop press with a wide enough gap for 1st gear to fit between the H-beams of the press. While a bearing puller might seem like an option, I advise against it due to feeling more sketchy.

I successfully disassembled the transmission by following a comprehensive YouTube video by Ezekiel and referencing the PDF repair manual for the T50 transmission.

During disassembly, it’s crucial to pay close attention to the orientation of each part, differentiating between front and back. Disassembly is relatively straightforward; the real challenge lies in reassembly. I also took the time to paint, and tap punch the backside of the components.

With the gears and all other parts removed, I meticulously examined them to identify any apparent issues. Unfortunately, nothing glaringly obvious or broken emerged. My best guess is that the shifter sleeve may be worn out.

Regrettably, my transmission is over 30 years old, and many of its parts have been discontinued. Consequently, locating replacement parts may prove to be a costly and arduous endeavor. If possible, consider sourcing a used transmission as an alternative to buying all the components needed for a rebuild. Cheaper that way.

My next step involves ordering the worn shifter sleeve, and a gasket kit to address the issue.

Stay tuned for further updates. On December 3rd, there’s an AE86 Matsuri event. Here’s the link to sign up! https://texasae86matsuri.wordpress.com/
