Transmission is leaking. Anybody else have this?
I put a clutch in this winter and a new slave cylinder while i was at it. After getting my car back together and driving around a bit i noticed that oil is dripping from the driver-side transaxle housing. The thing is, I never took that apart, just the bell housing from the engine to take the clutch off. Even if my new slave cylinder is leaking, i dont think it would leak from the driver-side transaxle housing. Suggestions?
Did you replace the seals inside there? Theres a little oring seal that you should replace. Mine leaked before i replaced this. Pull out ur axles, feel inside the hole and you pull out a little oring. Order new ones from Tom at CED throw em in and ur good to go. cause you dont actually take the trans apart when doing a clutch. You just take it off.

I thought I needed an axle seal too...so we cleaned up everything and I kept driving her a few more days to see if that was really the cause....I guess what, it wasn't.
I found the leak was coming from the top of the tranny, where one of the shifters comes out the top. Looked into how hard it was to fix...well I requires pulling the tranny out. **** that ****, so we drained out a small amount to see if that would help and it did. I guess they must have over fill when the car was built (common Ive heard).
Thread with some pics for a while back...

Look at the pics /\ ...it was leaking from the top all the way down to the output shaft.

M35 transmission
#1 the axle out put shaft has an oil seal housing on the transmission retained by 5 bolts. It has a roughly 3 inch diameter O ring on its outer circumference and a steel jacketed oil seal on the inner circumference. It is unlikely the 0 ring would be loose or come out. More likely the steel jacketed oil seal tension spring could dislodge. There is no "little O ring" inside the transmission shafts.
#2 the biggest reason for any leaks from the transmission is over filling. The trans holds 1.9 litres of fluid from dry, which means about 1.5-1.7 litres refilling after draining in normal service. There is a vent in this transmission , its hard to find, and the trans will leak fluid if it is over-filled, until the trans finds the right level and the "leak " through the vent will stop. FYI it has been known to happen that the trans., is over filled at the plant ....

i believe its leaking fromn the shifter cables b/c there is fluid running down the back of the transaxle housing. ill have to look again. i never touched the trans fluid while i had the trans off so im not sure whats up.
hard to figure, maybe the back up lite switch is leaking, I would not suspect the shifter pivots at all, but I would expect the fluid to pool a little in the back up lite switch area, but it could go back...all these parts are above the static trans fluid level
