I found am M17 4 speed muncie from an 86 fiero for $150...comes with 90% of the parts needed to manual swap a car. I have the option of buying a manual fiero, but my current fiero is my money pit and i have put a lot of work in. And mine is low miles in good condition, i don't see many manual v6s like that.

that being said. The transmission has 190k miles on it...I'm willing to risk it for $150. My plan is to go through it and check everything...synchros, gears, shafts, just everything. I am relatively new to transmission work..I am having trouble finding any M17 parts anywhere. at all. Is there a way to refurbish a transmission? Like how you can hone cylinder heads and replace piston rings but for transmissions. I want to get it closer to new, at least.

I know some MY8 gears can fit in the M17, but those are even harder to find. What options do I have for sourcing new parts? Does it matter that the gear is from a different transmission or not?

Also side note. $150 sounds unbelievable but this guy has a couple fieros and is planning on 3800 swapping one. We talked enough that I do trust he believes the transmission is ok. He said in the listing he is parting it out for cheap.

hottest (only) fiero in town

I don't think many folks here tear apart transmissions, including myself.

As a last resort, I end up drawing metal/plastic parts in CAD. Then I have a local machinist, that has a nice shop in his garage, fabricate them for me.

He has made a few items for me when I could not find a replacement source or the OEM charged ridiculous prices.

It would be a good idea to learn a free mechanical CAD tool and learn how to design parts from scratch. If that is beyond your skills, find an engineer in your area that can draw them up for you on the side. Then find a machinist that does odd jobs on the side. Make friends with people with local aerospace and defense companies that could introduce you to engineers like me that are willing to help you out. But they need to be local so they can be on site/hands on for the parts you need drawn up.

Sorry it's not much help, but as Fieros age, we are all going to have to start designing our own replacement parts. Maybe someday we can have a repository for our designs that people can download for a modest price, then find someone to make the parts.

I rebuilt my EGR Solenoid. I rewound the corroded coil by hand and fixed it for pennies on the dollar.

Best of luck to you.
