transmission questions.

[sasquatch]

the first is if i go to a "F" or "G" series trans will my speedo be telling me the wrong speed? 2nd, i was reading the trans swap Q/A and clicked one of the links and found a trans called a G36M-R, has anyone put one of these in a festiva, will it fit? here is the link: http://www.protegefaq.net/transmissi...l#transmission i have ALLWAYS wanted a 6spd festiva... just thinking about it is making me all happy, i dont know why lol.

I'm not sure, but I think the bell housing bolt pattern is different.

[sasquatch]

could i use a g5mr/g25mr bell housing?

[JPT]

Thanks. Now I can't get the idea of a six gear Festiva out of my mind.

From the little I've read, it IS possible, but I don't know yet if it's worth it.

[sasquatch]

how is it not worth it? is there any links that i can read about it? i dont think ive even heard of a 6spd festiva, i want to be the first...

Swapping bellhousing on our transmissions involves shimming certain items and there is no guarantee that would work. The first place to start looking would be the escort forum (www.feoa.net) and probably the mx-3 forum (mx-3.com). You could also check the mx-6 (mx6.com) and the ford probe forum (probetalk.com) but they would be using the V6 tranny which is a g-series but different bell housing than what we need.

the bellhousing is integral to the case half, so technically, it isn't removeable. The E, F, and G trans' don't share the same cases, so 'swapping bells' isn't feasible.

but what about swapping the g25 and the g36 bell housings

[sasquatch]

^^ what he said, or can i stick the g63 gears and junk in the g25?

From what I can see, the G36 has alot of different issues that make it difficult to use. You may not need to swap bellhousings at all. There is a 6-speed that will bolt up. The problems then lie in the fact that the speedo is electronic, it uses a cable shifter, it has differently splined axles, and there was a couple other issues. It has been talked about at feoa.net (escort forum). No one there has bothered to try to swap it yet because of the work involved.

...and that is what I meant by "I don't know yet if it's worth it". The above list is enough to make me pass on this transmission. Much work (and $$$$$) for what? The (admittedly cool) right to say "I have a six speed"?

from the thing that i read it says the g36 is from a 2007 and up mazda 3, that seams a little off, is this right? was the g36 only over seas, or can i go and get one out of some mazda/ford here? any help or links will help.

I read the same thing. If this is true, then the bell housing is definitely different.
