I have two 4 speeds, one out of my 1984 witch is a m19 with 51,000 miles on it. and the other one is out of my 1986 v6 witch is a m17 with about 110,000 miles on it. its going in my 3800sc swap. i am wanting to stay with what i have so no 5 speeds upgrades. just what 4 speed i already have is the better .
I too am doing a 3800sc swap and I too have two 4 speed transmissions. I have already bought the clutch and I am definitely staying with the four speed. One four speed is presently in my 1985 GT which runs fine and one was given to me condition unknown. How can I tell what "M" numbers they are? All info is appreciated. Thanks, Im Already leaning towards keeping the one that's already running because I know it runs and because I don't have to take it off the cradle to do the swap. Louis

Open up the front hood on the drivers side Near the brake booster on the side is a little white card its a build sheet for car . Six rows over and like two or three down u will see M something 8 17 19
Its very ez to just open the hood and look at sheet . I dont think theres anything on the trans to tell you. The build sheet tells u everyhting about the car with code numbers and letters. Outside color inside color Trans and gearing. Its called , service parts identification card
That link was cool to id what transmission u have as far differnt 4 speeds and 5 speed . But i didnt see anything to tell u what gear u have and that was his question about his 4 speed how to know what gearing he has . So i think the build sheet would be the best
If it has the ribs in the case, it is a M17. If it is a smooth case, it could be a M19 sport trans or a MY8 econo trans. (which was only about 8% of production manual transmissions in 1984). The only way to be sure is to count shaft rotations. If it is in an operating car, just look at the mileage.
Use the 86 with the 365 gears it is also a stronger case as the ribs show then the 84 tranny

no clearly the sticker wont help you. that's obviouse if the trans has been changed from 5 to 4 speed. course the sticker wont work. I agree with everything gall757 posted .
Any possible pics for reference as car as the ribbed case goes?

and thank you dan. I guess ill be switching transmissions in the next coulpe of days and putting my poly cradle bushing in also. everything is getting closer and closer to finish. next thing is fuel lines connections and coolant hoses. still have to figure those two items out. lol
did you open the link? Or am I missing your question?
Sorry , missed the link.

It's a ribbed case, so I'm guessing it's the M17. It's out of the car right now, so I'll have to figure out where first is and count shaft rotations to make sure. Thanks for the help.
