Official Transmission Swap Information (Update 21/05/2010)

does the Protege 91-'94 DX have a g series transmission ?
i know the 1991-1994 Mazda Protege DX ---motor will swap but will the trans swap with it


G15M-R trans can i still bolt up a bp to it this is the motor it has on it RF-MDT
or would a F5M-R trans work better the the stock one or is it a f series as well?

found it on here

No, the DX Proteges of that body style all have an F series gearbox. Only the twin cam LX Protege's have a G series.

The G15M-R is only for the Mazda 3's and there is no interchangeable parts with the BP's, KL's, or B6 trans.

BTW, the heading "transmissions", should be changed to "transaxles". ...unless we are talking about rear wheel drive cars.

it may be possible i want an f not a g.. look at gas i dont want to git up and go .. i want gas mileage at higher speeds.. higher speed lower rpm better gas mileage on high way.. and might i add higher top end.

ok im getting away from f and going to g ok now for the time being can i use the axles from the f or do i need to mod them? please tell me about that. and im going with a bpt i can use a bp flywheel and clutch right? if i go with g

You should have started a new thread.

Any K series gearbox will fit. (and Mazda V6 in this generation)

@ king62 - a G5M-R or G25M-R would bolt up to any K series, ive also heard rumors of the 4 banger manual trans (F25M-R and F5M-R) bolting to the K's? Seriously? Is this even remotely physically possible?

[Ryan]

No! different bell housings.

[KL01 FrEaK]

thanks Ryan, cleared that up for me

[king62]

yo thanks a lot master ryan......i will look for the g25 box.....and sorry...i should have really posted a new thread.....will inform of the mods later....iree...

I am sorry if I missed the post but how can I tell which transmission the junk yard gave me. I know it was pulled from a protege and it is working on my bpt.

Thanks

You're in the wrong forum. Search the V6 Technical forum and if you don't find the answer (and you should because it's been covered many thousands of times) ask your question again there.

for general knowledge trannsmissions from 323 bg 1.6SOHC and 1.3 fit mx-3 1.6 DOHC without any changes ...

[cricketol2]

is the final gear interchangeable between an automatic and a manual ? as long at it would be the same type .. g to g and f to f ?

In short, no. Totally different designs.
