Old beaten tranny.

The L-185 has a f52 transmission. I serviced it today. There is about 1/8 inch of mud in the bottom of it. Very small chunks and plenty of flakes to make a prospector very happy. (wrong color, its all silver) The guy that owns the trans shop in town said that if I can't get all the stuff out than it is best to leave it alone. Better stuck on the bottom than floating all around. I guess my question is how much of a beating can an old tranny take and still be OK?
Help! I'm stuck in the garage and I can't seem to pull myself out.

Nothing better than a nap on the creeper under the old truck.

Re: Old beaten tranny.

You will know that answer when the sound changes. Add 300 meters to the new sound and that is when the transmission reaches the end of its service life. Really a transmission could sound really bad for thousands of miles. Replace the gear oil and see how it goes. Watch for a suitable replacement transmission. There may be another model transmission that fits.

I guess I will know when I finally get it running. At the rate I am going, it will be 5 years. Does that mean that it is still good until proven to be junk?

Re: Old beaten tranny.

It means that it may be nearly impossible to know for sure from here. I am about14.5 hours and nearly a 1000 miles away. This adds to my STD. Senior Transmission Diagnostics.
Ask your local transmission person then follow the advice.
Old trucks make noises that are not heard in new vehicles. It is a similar situation to the questions, "Why does Grandpa make those embarrassing noises and smell unusual?" Grandpa is very old and can suffer some settling and audible leakage followed by that smell that only an old truck and Grandpa can make. https://youtu.be/-xRhkLDaj_I

Re: Old beaten tranny.

non syncro trans all get some metal in the bottom. It is just part of the beast. I would pull the top, flush out as much as I could. With new oil in it roll the shafts as feel for rough bearings. while rolling the shafts over, look for chipped or missing teeth on the gears. If all looks ok (minor, small chips aren't going to effect much) than I would use it. Bearings are the major cause of failure. if they are ok than the trans probley is.
Minor chips on teeth can be "dressed" with a stone to remove sharp edges that can lead to fractures.
