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
 
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.
 
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!
