If you buy a used truck with an auto trans. and the trans. aint been serviced often but seems to be in good working order and you change the fluid, the tranmission comes to pieces. Anybody ever heard of that. I've been told that if the fluid hasn't been changed regulary don't mess with it cause if you do change it it'll screw it up and to just drive it. How would you know anyway less you know for sure you can trust the previous owner?

When I changed ATF in my tranney a few months back, I broke off 4 of the bolts holding the pan on. Nothing I could do to get them loose. They were froze tight. All 4 had holes that were exposed and open at the top, and I assume were corroded fast. Those in blind holes were not corroded. Resorted to lotsa silicone gasket material on the oil pan on reassembly, and it's held so far. You might want to consider your options when you get to changing oil - are you going to get into trouble with taking the pan off? I suggest that maybe sucking the fluid out with a tube down the dipstick tube might be an option. Also, you might consider putting a drain fitting in the pan for future drainings, and another thought - put a magnet on the bottom of the pan before reassembly. Mechanic put one in mine, and after a couple years operation, there was a suprising amount of magnetic dust and dirt attached to it.

Heat, time, and dirt all react with ATF (and any other hydraulic fluid) to increase viscosity. As the fluid gets thicker it compensates for wear in the clutches and erosion of metallic parts. Same thing applies to powershifts on tractors.

Either change them every 20,000 or never. Ran accross some Chrysler products in the mid 90's that recommended never changing the fluid. The three shops I work most closely with all say an automatic is good for about 150,000 or until somebody decides to change the fluid.

Seems I have the same problem when I put a different engine in pickups. So when the bolts are removed I have the trans. gone through too.

It also seems to me that things like that happen frequently. But if it fails shortly after such a change, the failure was imminent anyway. If you do not change it yourself, be sure to use someone you trust.

I had the trans fluid changed by A1 transmission using one of those oil exchange machines. I thought I would check the level to be sure it was full after I drove home, a distance of about 5 miles. What I found was very used fluid which smelled burnt and was a dark amber in color. I went right back and they pulled the pan and drained the converter and filled with new oil. Of course they said this is the first time it has ever happened. Stay away from oil exchange machines. Instead drop the pan, change the filter/strainer, drain the converter and then fill using the manufacturer recommended trans oil. There are so many tranny oils now you have to be very careful to get the right one. It can change from one model year to the next as the manufacturers try to improve gasoline mileage, improve the performance of the transmission electronic pressure controls, maximize the torque capacity fthe friction materials, and eliminate the slip stick (shudder) of the converter clutch.

A local tire and mechanic shop down here refuses to change the AT fluid and filter on a tranny with over 150 K. He got tired of being accused of tearing up peoples transmissions when all they wanted was an oil change and thats all they got.

It must clean out all the gum that holds them together at that age.

Years ago when I worked in a service station (remember those?) we saw this happen many times on trannies with over 100K miles on them. They were fine until the fluid and filter change. Then they started to slip.

A neighbor is a trans mechanic. He says the same thing. It is the sludge and gum dislodging that clogs up the filter, valves, and ports then burns up the neglected slushbox.
