Adding oil to transmission?

    I have a '93 Suzuki Carry and would like to check the gear oil in the transmission. But, other than locating a dust cap at the top of the bell housing, I can't seem to find a plug for where you can check the oil level or add more if needed. I did see a plug with a square hole on the bottom of the transfer case, which I suspect would let me drain the oil. Any help would be appreciated. Thank you.

    You will have a plug with a square inset on the driver side of the tranmission. A 3/8 socket extension will be what you will use to remove the plug, be careful when removing not to strip the plug. Once you remove the plug there will be a plug in the rear of the transfer case. Remove it also. Your transmission and transfer case are conected so when you put fluid into the transmission you are filling the transfer case also. Use standard gear oil 85 weight to fill tranmissions and differentals.

    If you do strip the plug you can buy one at the local hardware store in the pluming department. Buy one that you can get a cresent wrench or pliers on.
    Speaking from expericance on this one.

    Thanks for your reply. I have a '90 and a '91 Suzuki, both have the plug with square inset that you mention. The '93 doesn't have that plug. There is a round hole in that location that was never drilled and tapped. Any other possible location to fill with oil? Thanks for the advice about replacing the plug with one that you can get a wrench on, I'll do that for the older Suzukis.

    I have a 93 Suzuki for sale. I will look at it later today and let you know something.

    Found it!! It's on the passenger side, at the back of the transfer case, somewhat hidden by the muffler. But if you get your head all the way under, it's one of those bolts with a square indent. Pretty easy to find once you know where it's at!

    Mine was on the drivers side like they said but I used Syn oil 50W as in the winter oil was so thick made it hard to shift in the cold .
    You would start it cold with the cultch in idle a min. let the cultch out and the motor would stall .

    My 2 cents

    My truck is doing the same thing when its cold, you let the clutch out it stalls. Any idea how much oil it takes when changing it?

    Not sure if you ever found an answer for this. I can't remember how much I put in but you fill it up til the oil level is at the fill hole and starts to come out.

    I have also stripped out the plug. I just ground a bolt head to fit the hole, welded it to the plug then welded a nut on the end of the bolt. It works I guess.

    What about a syn gear lube, or would a syn motor oil be even better?

    Lil Red and bigguybigguy I have the same issue as well, i never push in the clutch to start and it would always jerk forward a little bit. This morning when it was 14 F out i started it with the clutch pushed in...much easier when i got out to scrap ice....the thing started moving foward as i let out the clutch. When warm...no problem I had wondered if it was the pilot bearing or maybe to thick of oil...i think i have 80-90W gl-4 in it now. It also seems like when cold...when you shift it is like you are applying the breaks and it slows down...i'm thinking this might be due to cold thick oil as well.

    I had the same issue with my 95 in the cold. Once it hits the -10 and colder the trans drags the engine down when starting. I put fully syn Royal Purple 75-90 in my tans and diffs. I use my truck mailnly in the winter time with tracks on it so I wanted a high grade of oil to keep things well lubricated in the cold. It helped with the starting issue but when it’s -25c I still gotta push the clutch in. I think it took about 5L of oil to do both diffs and trans n t case. Hope this helps

    Everybody should take note that the Suzuki requires GL-4 and cannot use GL-5 due to the bronze syncronizers. GL-5 eats yellow metals, and oils spec'd for both, only spec GL-4 for differentials ( no yellow metals ), the GL-5 spec is for transmissions. The viscosity spec is 75W90 though

    I daily drive my Suzuki and I put in Redline 75w90 GL4 in the trans. Cold lugs the trans for sure, but it's workable

    Can you please clarify the quoted post?
    GL4 for trans or diff?
    GL5 for trans or diff?

    GL - 4 for the trans.
    I too use the Red line.
