fm145 is dying! (like you havent heard that one)

[kunar]

my fm145 has started making a strange ticking sound. it seems to be in direct relation to the input shaft speed. its also grinding when you upshift. i can drive it without grinding gears, atleast not much, but you gotta be really touchy with it. now i know its junk, and i want to swap in a mazda, but i need to make this transmission any better if i can, and make it last just a little longer. its got about 210K miles on it and its started the grinding maybe 10-15K miles ago. its never been much of an issue, i just have to shift a little slower. but today it started clicking. i drove to columbus and back (300 miles total) but this was over about 5 or 6 hours total. toward the end of the trip is when it started sounding strange, and it got louder as i drove. when i got home, i drained the fluid (it was only a couple months old) and it was dark but not black. it had a little brass shavings floating around but not a ton. i added 2 new quarts of 75w-90 and took it for a test, and it was better. its a lot quieter but it still does make noise. basically all i wanna know is can i do anything to help slow down this failure so i can drive it another week or so?

Hope I didn't cause you to need a new transmission. Althought, as we talked today you already know those are junk.

hey, no worries bud. 300 miles is only a weeks worth of driving for me so i would be needing it soon anyways. now i have a little cash to buy it though

If it's clicking or knocking in neutral, it's having severe chest pains. When it will actually die is a wild guess, but when it does, you're completely stuck.

yeah, if i put it in neutral and let out the clutch, it ticks in time with the engine. it seems to be in direct relation to the input shaft. so is it an input shaft bearing or something along those lines? what about the hard shifting, can i try to thin the fluid a little or something along those lines?

any body have any idea whats failing and why? whats it gonna do when it finally lets out?

My FM145 made the same noise. It sounded like a little clicking, nothing turning up the radio wouldn't solve, and it whined when the clutch was out and the truck was in neutral. The clicking turned into a clunking and that turned into a noise that sounded like lugnuts in a washing machine when I would drive down the road. I found another FM145 before it started making any more noises.

mine was doing that to. i rebuilt mine and now its fine. when i had to rebuild mine finally i found the only thing wrong with it was the bearings were all shot.(all of them) wheni took the tail shaft bearing off it fell apart in my hands. but the problem was the input bearing went bad. i abuse my fm145 all the time and i donr ever have a problem.(note when i had to rebuilt mine it had over 300.000) just put a rebuild kit in it and youll be fine. make sure u get the one with the update.
