Year-1994
Engine- 4.0 v6
Trans-Mazda M5OD-R1
Drivetrain- 4x4
Transfer case-manual
Heres the deal. Truck began shifting hard. I had not replaced the fluid since I bought the truck in the transmission.
So I replaced it with Valvoline Multipurpose ATF, it stated that it meets the Mercon specs needed for the transmission.
This helped the shifting when cold or when going for short drives.
Went for a 150 mile drive that required no shifting or stopping, the truck stayed in overdrive the entire 150 mile stretch. When I left the highway and was on the off ramp I put the truck in neutral and coasted to the stop light. The light turned green, I clutched to the floor and hit a "wall" as I tried to put it into first, then hit a "wall" as I tried 2nd, 3rd, 4th, OD. I wound up shutting off the truck and pushing it hard into gear with the clutch depressed, then starting the truck up.
Now, I got home and immediately checked my transmission level. It was just fine, I checked my transfer case and that was just fine also.
So I took it for a drive and it drove fine and shifted nice and smooth.
So I have been driving it 6 short low speed miles to work and back everyday this last week. No problems shifts great. So I got curious. I went for a drive and beat on it. Getting the motor and trans up in the Rpms and getting the transmission hot, immediately the "wall" came back. I once again checked all the fluids and they were fine.
I did notice this though. When i was in the garage, transmission hot, transmission in first gear (by the way the truck will shift into all gears when the motor is off and clutch pushed in, no problems) and then started the truck. When I let the clutch out, so from the floor, I only had to let it out about a 1/4 of the way to get full engagement of the clutch. When normally or when cold, i have to let it out till about half to get it to engage.
The next thing i did was crawl under the truck and pull the viewing window off and look at the slave cylinder in action. With the truck off, I had a friend push the clutch in to the floor and watched the slave cylinder, If I had to say the distance it traveled I would guess a 1/2" and thats all. This seemed like a low amount of travel to me.
The clutch fluid reservoir stays full and does not empty, therefore this leads me to believe that there is not a leak in the system. Unless, there is an internal seal that has gone bad. I was thinking of bleeding the system just for the heck of it to see if that made a difference but have not had the time.
The main factor to remember in all of this is that this problem is time and heat sensitive.
Now to this date, I have taken it to two dealerships, with the trans warm to have them do a "diagnostic test" needless to say, $500 later, none of them were able to "safely" say what the problem is.
I am a college student and can not afford to just have someone taking things apart till they find the problem, so I am coming to you all. Hopefully someone has had this problem or knows what is going wrong.
Thank you all,
