I’m genuinely surprised. The M50D is known to be reliable, as long as you keep fluid in it. But I haven’t heard of any with as many miles as yours.

Maybe 200k miles is the service life? I mean, that’s right about the life expectancy of most cars sold in the US (12 years/200k miles)
No it isn't the M50D is always known to be junk. It had an internal slave cylinder that would leak and get clutch fluid onto the clutch disc. The Ford ZF5 manual was much better.

Weird. Rangers with the M50D don’t have those issues.

Then again, yours might be the highest mileage one on the road.

It's characteristic of that transmission.

Mine is not the highest mileage on the road. I know of many Ford F150/250's on the road with over 500,000 miles on them.

I know of a couple of guys who after their trucks fell apart, removed the 300 straight six and used them for irrigation pump motors.

I find it fascinating.

After a lifetime as a car geek, who has worked in engineering focused firms, an insurer specialized in classic cars (where we had our own mechanics and body shops to train our staff), and for a Detroit Big 3 automaker for years, as well as doing some anonymous side work for automotive blogs... I've never once met a person who considers a transmission that required two rebuilds in almost half a million miles to be a bad transmission.

Even a Toyota Land Cruiser - known for very high long term reliability - would still be on its second engine and transmission rebuild after half a million miles.

Woo, woo, woo..... I'm calling you out on this one. First of all it's not an automatic transmission (which needs rebuilds), it's a gearbox, just a shaft with gears on it. BTW, Toyota's are not all that, they got their reputation from the 1978 to 1982 models. In fact in an interview with the president of Toyota he stated that if they knew how good their cars were at that time, they would never have made them...lol, hows that for customer comes 2nd.

You can literally rebuild a manual transmission. I've had it done on old track toy Mk3 GTI since it was cheaper than replacing it.
