Over the time I have owned my car, my M5R2 has been subject to wear slowly degrading the blocker rings and possibly other parts, leading to a grind in second gear.
Essentially this grind occurs only in second, whenever it is selected after a downshift, and when upshifting from first unless shifting very slowly at low rpms.
Do to cost and possible future upgrades which may eliminate the m5r2 from my SC, I would like to rebuild this transmission myself if possible. Therefore, from logic and my current knowledge, it seems the things I must know to perform this will include:
1. A method for diagnosing which parts may be worn to the point of causing misoperation, and the names of these parts.
2. The best source(s) to acquire the necessary replacement parts, from both a quality and price standpoint.
3. The tools, especially unusual tools, which will be required for the process of removing, rebuilding, and reinstalling the transmission. Also sources for any unusual tools or possible substitutions would be useful.
4. The instructions/processes, torque specs, and other various information which will be necessary for a person who has no previous background in this reguard to perform a proper quality rebuild without significant unexpected obstacles, including removal and reinstallation of transmission.
5. The location of any current documented information which would be relevant to this task.
6. The length of time this task normally takes, and any other significant information I have not accounted for.
From what I have kept track of over time, it seems to me that I probably have a worn second gear blocker ring, and the synchronizer assembly itself is ok. I think this due to the fact that only second gear has the problem, and it occured gradually from improper shifting (not me ). It also looks like current prices for parts to rebuild the basics are running around 400 dollars, does this seem ballpark? Finally, it doesn't look like the process is overly complicated. From what I can tell, there may be significantly less work involved than in changing motor/trans mounts, hence this is something that could be performed in a day.
Thanks a lot for any help you can offer me!
