OMG! What now with the *&^%$ Mazda b-3000 tranny? clutch?

[nancylee]

Please. I am at my wits end with this truck. 1995 Mazda b-3000 4x4 manual 5 speed tranny, 3.0 engine. History= Last year I replaced the slave cylinder and master cylinder, and has been fine for at least 14 months.
Yesterday as I was driving past a school in residential area( so I was Going slow). My truck seemed to lurch as I was coming through a dip in the road. As I tried to shift into 2nd gear I got nothing but a sound like my gears were just rubbing each other but had no engagement. The lurch kind of felt like my u-joint went out or dropped a drive shaft,kind of like heavy shifting. The clutch pedal feels normal and it feels like it is shifting correctly but no gears are working. Also when I have the truck in gear motor off I can push the truck and it stutters forward or backwards. I looked in the housing and the slave cylinder looks ok. no leaks. I dont know what to do next. maybe dynamite? Thanks in advance for your thoughts. You have always been a great help in the past.

Well dynamite will just make it worse... You know what I had a problem like this on my 88 F-150, if only I could remember what was causing it. I need to go play with it some more and I will report back with my findings. But it will probably end up to have nothing to do with your problem. Well see.

I had a problem in a f150 similar to yours. The forks inside the transmission had somehow jammed, apparently common on high mileage m5od-r2's. I was able to fix it myself by removing the shifter and aligning all the pieces I could see inside the transmission so they were a mirror image - side to side and forward to back. I'm not saying this is what's happened to you but is an area to check.
Good luck,

Richard

try this i recently got a ranger for cheap cause the transmission was supposedly blown(the shifter wouldn't move at all) after i dropped the trans i decided to see what was wrong pulled the top cover and it was the fork for reverse jammed popped it back into neutral and now i can shift through all the gears fine.

... Sorry...
Sounds like you stripped the input/countershaft gears.

Super common failure of the M5, and requires a complete rebuild of the transmission. Good news is you can save the shift rails, tailshaft, and the case.

Usually cheaper to find a used transmission.

i have seen the clutch spline on the disk crack and cause this on the 8 in clutches....usually when swapping a 4.0 in. i have had guys not want to buy the 4.0 starter, flywheel, mt engine plate, and clutch kit to save some coin when starting with an automatic donor and replacing a 2.9 in a fm146 truck..

the trans usually dies first but i have replaced the clutch disk....twice for one guy...then the trans died like a week later.

fawker got another 146 and killed it too.

then got a 2.9 m50d...kept the retarded clutch and broke it again.


i went to the junkyard and got all the shit for a 4.0 clutch setup
....got lucky as it was all pretty fresh. 20 bux... never even said thanks

dude sold the truck for 600 bux because it had some trail rash etc but no rust at all..... and never told me he was selling it about a month after that.

and people think i am an asshole.






so let us know whats up with it.

 

[bobbywalter]

well i broke my 4.0 clutch the same way.



whoops.....still tougher then a 2.9 clutch
