SOHC and DOHC tranny the same?

Post by jumboplay »

Topic as question. I'm hitting the junkyard and gonna try to hunt down another one. So sick of syncro problems (my fault but damn it, what can I do now?). And a post that just came up said that certain types of gear oil eat the syncros? Anyone know, damn it I've love to hear about that!

Oh I forgot to ask...is there another car's transmission I could use? Mine's a 96 DOHC. Some sort of Protege or something? Thanks again guys.

Sucks to have transaxle problems, I know. :(

Make sure the gearoil your using dosen't contain any sulfur. If I understand right, it was reccomended not to use Mobil 1 in some of the earlier G series v-6 transaxles. The PGT guys were complaining about problems when using Mobil. As far as the F series, like the one in your case, I would'nt know if sulfur would contaminate your trans. Perhaps Mazda changed the bronze/brass parts to better materials? A bit more expensive, Red Line oils have NO sulfur, and was highly reccomended by many racers/auto techs alike. I'd try that first.

A 95 Protege trans will bolt directly to the b6 block, however the gearing is slightly taller. You can still use the Mx-3's clutch and flywheel.

the sohc tranny uses a long axle on the passanger side. and the dohc tranny uses a half shaft axle on the passanger side they look pretty much the same driver side axle just different axles on the passnager side. but i face a friend who is going to see if the DOHC tranny will fit on the sohc engine. laters

the jack-shaft does not concern the tranny, just the year of the car. the jack-shaft bolts to the back of the block, so a sohc motor will not have these. you can use the 92-93 axles on any year mx3, but not vise versa

the 92-93 axles have a smaller diameter shaft that goes into the tranny....you can use them on any year mx as long as they are an F tranny if you put in a G tranny you need to get axles from a V6 mx or protege or mx-6

vise versa my @$$? wow, the maturity of this board keeps getting lower. this was in reference to the passenger side as i was talking about the jack-shaft etc. i'll just leave it at that, you can take it for what it's worth.

it's a proven fact that you can use the sohc PASSENGER side axle with the 94+ cars.

ok, i got my car back today. the tranny is the same and it fits. there is some slight diffrence ( bolts ). you will have extra bolts. obviously, the dohc block is diffrent from the sohc but other then that, everything bolts up perfect.
