Hi,
I have 2 questions, please help me Guys.

1) Seems to me that we have 2 manual gearboxes or gears sets in 2nd generation right ?
My question is: have they any factory designation ?

2) I know gears ratios, but I dlike to know numbers of teeth for all them

Could You please help me ?


(I hope that I expressed it proper in English)

1. there are two basic manual transmission designs used in the FC.

the non turbo cars get an M type gearbox, which was introduced in the 1979 Rx7, and is used basically in every RWD 4cylinder/non turbo rotary car mazda made until 2005. so its in the Miata, Rx7, Rwd 626, 79?-93 B2000/B2200 trucks.

the turbo gets an R type gearbox. again the transmission is shared with other cars, the FD, Rx8, MPV,929.

that's fantastic, looks like quite large replace parts market.
thanks for info I need to examine all this carefully...

At beginning the question, and I know it might soud stupid, but I have to avoid language errors: about what should I have to exactly ask if I want '86 non turbo gearbox ? I mean "Mazda M ....(prefix or some)"gearbox ?

and what about teeth numbers ?

i'm not sure i understand the question, if you want a 1986 non turbo gear box, that is what you would ask for. maybe you do your homework and look up the mazda part number (the only place that would have sold it new) and use that.

the part number for the 86-88 NA coupe was M582-03-000

Hm I see, and Im sorry for confusion.
Unfortunately I am not sure how to properly ask about all I want to ascertain.
So I need to ask for a bit time and patience, Im sure we can communicate succeed this way.

The point is that I'm not looking for new parts in the catalog, I'll look for them in scrap yards in Central Europe.
I need to know how to recognize them. I mean if they have any markings I must be able to read them.

Therefore I need to ask a bit different way, will i find this M582-03-000 designation also on the box or just in the catalog ?
You know will there be something like on this picture: http://home.centurytel.net/FishinChi.../engine_sn.jpg

ah ok, i see what you are saying. unfortunately mazda does not put any kind of ID stamp on the transmissions (well in the US the miata transmissions get a VIN tag)

basically the R type transmissions have a removable bellhousing, and a flat pan on the bottom. the M type or smooth case, do not.

OK thanks a lot, this complicates matters a bit...

... KIA parts compatibility wonders me too.
May Dad has '98 626 and my Bro have '00 KIA Clarus 2 a lot of parts looks the same to me.
I dlike to know 2nd gen gears teeth count, and all I can find is final ratios. Is it possible to determine this ? I do have this data but only for 1st gen

I don't know if KIA gears fit the same. I read somewhere that there is a KIA rear end swap for 79-85 first gens, but I have not heard if there's anything like that for the 2nd generation.

Here's a picture of a N/A transmission (M-type)



And here's a picture of the TII transmission (R-type)

Thanks for photos

Mechanics from KIA workshop told my brother, that his Clarus is essentially Mazda 626. They argue that KIA bought technology from Mazda ...
... so I'm wondering how much truth is in all this, and then how many cheaper alternatives may be hidden in KIA cars. I think that quality should be comparable, KIA offers here 7-year guarantee, its very boldly by Polish standards.

A quick read up on wikipedia shows that the Kia Clarus was based on the Mazda Capella, known to many as the 626. However, the 626 was only RWD up until 1982. Wikipedia only shows that the Kia Clarus began production in 1997, so I'm thinking it's FWD.

yes the older Kia's were based on mazda's but Kia didn't have any RWD cars here except the Sportage (we didn't get the Clarus). the sprotage diff works, but the transmission is different.

in the 90's we were a Mazda/Kia dealership, so there are a lot of service parts that interchange between say a protege and a sephia, but the only things that work for a rotary are nuts and bolts and a ring and pinion

damusto

I saw nice link with Miata engine swaps options some time a go, I cannot find it now, but I remember there was one KIA engine too. Its true all KIA cars that I know are FWD, but Miata is RWD right ? I will try to get this link again
PS
I think that some KIA commercial cars are RWD

Well, keep in mind that Hyundai is owned by Kia, and they now have RWD cars. The Kia Sportage was a RWD (or 4x4), so that could share some similarities with a mazda transmission.

damusto

good idea thanks I will try to check this out

old kias in various countries often used the redundant mazda chassis designs and engines /drivetrain

however ,, talking the R boxes ,, ford use an evolution of it in the US broncho,, known as the toyo kogyo box TK5
and that may be a better place to look for internal spares

methinks the M box is known as M5 in ford speak ( though cant confirm )

a lot of 80's ford manual's are R boxes, more than the bronco. the M type would occur in the courier, as its a re badged mazda truck, but off the top i can't think of any other RWD ford that would use it?

fbse7en

yeah, according to http://www.drivetrain.com/parts_cata...rhaul_kit.html the TK5 was on '83-'87 Ford Ranger's, '84-'87 Bronco 2's, '86-'87 Aerostar... AND M5TXA trans are FWD.... (not to be confused w/the MX5, yes thats how its listed- trans found in Miata's)
