Noob question don’t laugh

The clutch fluid is leaking in our Mazda B Series. It’s done 100,000 miles and I read it probably needs new master slave thing which I can’t afford right now. Anyhow I’ve got this clutch fluid that stops leaks and just want to double check I’m putting it in the right place. Is this where it goes? (See arrow)

yep. thats the spot

Yep, right there - be ready to top it up often. I kept doing that until it was time to take it to a pro.

I think the slave cylinder on my ‘01 Ranger was located inside the transmission, so replacing it required the removal of a cross member, transmission pan, new fluid and filter (I think). Anyway, it was a painful trip to the shop and my wallet took a $400 hit.

I’m not sure what that stop leak fluid might do to a tranny if it leaks inside. My guess is it could gum things up - any transmission specialists on the forum who might know?

Good luck Phil.

I imagine you’re going to need to bleed it as well if it’s leaking and air is getting in. On my wrangler I had to regularly fill and bleed it until I finally pulled the trans.

Yeah so do yourself a favor and dont use the stopleak. There is a good chance it will cause more problems.

And would be a great time to do a clutch while you’re in there while the transmission is out. Esp if the trucks at 100k

Hi Duke,

I am a bit confused. The M5OD does not have a transmission pan. It does take ATF, not 90wt gear oil, but there is a need to plug the tailshaft housing to keep the gear oil in the trans. I used the shipping plugs from the assembly plant as they were everywhere around the engine dress line. Still have a few somewhere in my tool box. The clutch release bearing does require breaking the line from the clutch master cylinder to the release bearing prior to transmission removal. It is not a hard job per se, but can be a bit messy if the trans tailshaft leaks. You can also use a baggie and a zip tie to seal the tailshaft and it works well until you snag the baggie during removal if you do not take care. If a 4x4 it benefits to remove the transfer case and not pull as an assembly as it is hard to manage under the truck unless you have a vehicle hoist...

Best,
Phil

my guess is the stop leak product will not do anything good except stop the leaking hopefully. but, with the age and 6 figures on the odometer i honestly do not think it harm much either. if it was mine i would give a try. maybe it will help it last long enough until you are ready to repair it etc.

Thanks Phil - I didn’t do the work myself - it was WAY outside of my skill set at the time so I took it to a transmission shop. I was really just going by what I recall the shop telling me what they did.

I do know that I was back within a week when I started hearing a clunk every time I changed gears - not necessarily inside the tranny, but what seemed like the whole truck itself - like something important was loose. I crawled under to take a look - there were two bolts that held the tranny (maybe it was the transfer case) to something under the truck (I think it was a cross member between the two frame rails?) Anyway, one bolt was missing and the other was in place but only one or two threads deep. ? It was a fast trip back to get it straightened out. After I turned the air blue, they got me back on my way.

I can attest to that. I owned an 84 that took 90 weight gear oil. Then I owned a 93 that took ATF. Yes both manuals. The 93 had a Tremec from Mazda if I recall. But I was an idiot and put 90 weight gear oil in the 93.

She drove great and shifted super smooth for about 3,000 miles. Then synchro #1 went. Followed by Syncro #2 and when #3 started going I took it to a shop and then $1600 went out next.

Yeah it's always fun when that stuff happens. One mistake that happens at nissan I people will put GL5 gear oil in the manual transmissions instead of GL4 and it causes so many issues.

Hahaha lol

Sorry, but yes. That is where it goes. Too bad you dont li e close by. I have done a ton of work on manuals for 150s and rangers
