Unlucky...

I was cruisin' Ebay and spotted this. I'm not affiliated with this business at all so this isn't an endorsement, but thought you might be interested.

I'll break the pricing down for you, as I just did a lot of tranny work:

New Mazda Tranny - ~$2200-2300

Complete Rebuild: Seals, shiter forks, hubs, syncros etc - > $2300 in just parts

5th gear Syncro done at a shop - ~$800 (if you pull the trans)

JY Tranny from a '94 or '95 w/ low miles - $700

5th gear Syncro DIY - ~$60



I'll keep advertising for the guy since he was so cool to deal with:

That trans was still for sale 2 weeks ago.

My mistake. I could have sworn I saw an "FD" in that Ebay listing. Sorry.

j9fd3s,

For my clarification, are you talking about the entire 5th gear or just the synchro?

I hadn't heard of alot of problems with the gear itself, just the little brass synchro. Of course, 5th is just an OD, so I wouldn't expect it to get alot of hard use.

Also, you might be able to confirm this, but Unlucky may not want to wait TOO long to fix it. My understanding is that when the transmission is in reverse, the synchro is unsupported, and if it's broken, as mine was, it could simply fall off the shaft. Obviously this would not be a good thing. In my case, I was lucky. It was broken in two places and when I went to pick it up off the shaft, it just fell off.



Unlucky... the transmission is really not that bad of a job to take out. Doing this yourself and then taking it to a shop would probably make it much more affordable.
well what happens in the synchro breaks and then it rounds off the gear teeth, because theres no synchro. i should take pictures, its really hard to explain how a tranny shifts

Didn't do mine, but a lot of first time tranny guys do theirs. I've seen a pictured step by step on the 5th gear syncro on the web before. I'll start searching for it.

funny... 3 shops quoted me $150 - $200 plus parts if you pull out the trans yourself

I'd also like to know how hard it actually is to replace the 5th gear synchro as well...I'll also be doing the gear select spindle...is this a major project or not so bad. i'm just talking about after the tranny is down.
