I'm curious as to what kind of mileage people have found on good used ZF transmissions.

I have one that had 120k on it when I got it. Drained the oil cleaned it a little and installed. So far it's good no issues.

Mine has over 300k on it now, 3rd gear syncro is toast but the rest are good. I'd say most jy trucks have well over 150k.

Thanks guy's found one with 138K I guess I'll check it out tomorrow. Thanks again for the input.

Thank again for the input finally was able to get a good working ZF.

Awesome!! You'll love it!!

If you've done any research here, there's lots of good advice for these. Mine is always "get quality hydraulics!"

What qualifies as quality hydraulics? I'm hoping to get mine in before next spring and am starting to collect parts.

Well all I can really say is avoid the chain parts stores. I used one and had to pull the tranny a year later to do it again. Second slave came from BCB.

Good to know, thanks.

I'd source from a tranny shop or something. Just not a job you want to do more than once in a 5yr period.

I can get sachs clutch slave & T/bearing set the clutch master that my supplier has is doorman not thrilled with doorman but at least that's the master not the slave. Thanks it felt like a never ending search to find. Let me know if I can help with parts.

There are two (or more) different master/slave cylinder sets and they are designed to work together with matched bore/stroke sizes.

Sounds like you're on the right track. I remember when my first slave let go. The night before a big run. Took the wind out of my sails for sure! It started to fail while I was waiting on my Atlas to show up, so I babied it along for a little while and replaced it with the BCB one when the Atlas went in.
