DIY tranny rebuild

[rsx858]

So i want to learn how to rebuild the trans on my second gen... such a weak link in the drive train i figure there is a lot of money to be saved by doing it myself. I have never cracked a trans open before but i think i can handle it.

-Any suggestions on literature or instuctional books / vids that i should get?

-what special tools and or parts should i get if i plan on doing this regualrly?

Thanks

a madza factory repair/service manual should help . a list of tools needed , i'm told. ralph

[rsx858]

the factory manuals pretty expensive right? Are these trannys basic enough that i could learn with a generic how to book for manual transmissions

Would get a manual. Search eBay--usually cheap.

If you do not have a hydraulic press and bearing separator, as well as assorted seal drivers and clip tools, you may be tackling too much of a project.

Assuming you have some paper for your printer (or can work from a screen) why buy a printed factory service manual?

PDFs are abundantly available:

I've never cracked a transmission before, but I pulled a few of mine apart, and made some minor repairs (replacing pins etc.) and diagnosed bigger problems without too much trouble using the FSM.

Happy to help. I have some well thumbed copies in my garage.

Don't own an RX7 without a copy of the FSM!

Don't own an RX7 without a copy of the FSM!
Especially since having a FSM is required by the Improved Touring rules...

There's also the option of treating trannies as a disposable item. Buy 'em (at the junkyard), race 'em, break 'em, replace 'em, repeat process. This may be cheaper, and it's certainly easier.

One other thing: pals give me grief for my granny shifts, but my trannies last much longer than most RX-7 guys'. Half a pause on the 2-3 shift costs what, a tenth of a second? But my trannies always last a season or more. :D

I considered building my own, but when i looked that the time, the economics and the risk, it made no sense. It would take me a number of builds for the $ aspect to be justified.

I used Bill at comp Gears outside of Boston (thanks to Andy and Flatout for the recommendation) and it was about a thousand for TWO transmissions. yea, and I can TRUST his work!
