i got some problems with my tranny and im going to have to put money into it anyway, or get a new one. i want to rebuild the transmission and beef it up. meaning put some parts in it to make it be able to handle more horsepower and loose less power through the trannsmission. does anyone know how i can do this, what parts i need to buy. if anyone could share there experience with me that would be wonderful.

Thanks you

 

I think you can Cryo-treat the gears and pretty much everything going in the tranny to make it all a little stronger.
I'm pretty sure you can't do anything about the loss of power in the trann. Thats just how they work.

 

You might want to contact G-force transmissions, they rebuild/strengthen other transmissions.

Then again, a one-off project like that would probably cost an arm and a leg and you would have more gear noise with straighter-cut gears. I wonder what other cars use our transmission...I doubt there's any significant market for a beefed-up aisin transmission. It would probably be cheaper to swap in a T-56. Or maybe the cryo thing would work, that would probably be your only semi-affordable option. Also talk to RX8PR, they beefed up the input shaft and something else IIRC.

 

doesnt the 6 speed miata use the same tranny?

 

Call AWR Racing, they offer a rebuild process they worked out with MazdaSpeed Motorsports, will cost you around $3000 + replacement parts

even then it will always be a weak trans

similar to the Miata 6 spd trans but not the same

 

I need to go to school and learn only how to rebuild Rx8 trans! $$$$$$$$$$$$$$$$$$$$

I haven't looked at a rx8 trans but most aren't hard to rebuild "IF" you know what is what and where things go.

 

They don't just rebuild it, they build some special parts and spend a lot of time dialing in very strict tolerances that you won't find in a Mazda repair manual

 

if you are going to spend the money to rebuild it, have the cryo-treating done. I went to an automotive school and we learned about it. It strengthens the metal BIG time.

 

not necessarily ....

I forgot to mention that part of the $3000 charge is from them having all the internals REM finished:

damb that might be too much for a college kid like me to spend. im pritty sure i can get a new tranny for much cheaper. Although it would be nice to try it out.

 

yes, but then it's just a production trans with all the usual flaws and likely short life in a stressed use situation, these are intended for track competition
