A555 A520 OBX Hybrid Transmission Build Tips
A555/A520/OBX Tranny build tips
I am building my first A555/A520/OBX hybrid transmission. This unit is an A555/A520 hybrid with an OBX LSD installed. You cant get the OBX for the A555 directly, but you can swap in an A520 intermediate shaft and ring gear and get the OBX in an A555...and that is what we are doing here.
I have been building engines for years, but this is my first manual tranny. Since this is my first tranny rebuild, I am wet behind the ears, a green horn, Im sure to make a small mistake or overlook something that an experienced eye might have not missed so I thought I would just ask:
What are some of the common mistakes made when rebuilding a tranny?
What do I need to be sure to do or not do?
How do I determine if a synchro is worn (out) by visually inspecting it?
Assembly tips, etc.
I have everything needed. Two same year trannys, an A520 and an A555, a complete set of bearings, seals, and synchros for this unit. It's the late model 89 style A555 with the large nut on the end of the intermediate shaft rather than the c-clip.
