Anyone had any issues or concerns with it? (I know of the parking rod plate recall on 2017 Job 1 trucks.)

 

Been a few reports of odd shifts. But no major issues. The transmission in base (ZF HP26) form has been around for a long time and the real issues were worked out long ago. Stay within limits of it and you will be fine.

 

 

18k on mine and running like a top.

 

only one small issue is a shudder when in reverse...does not happen all the time. I have 24k on mine and its a smooth trans. for sure

 

There are a number of reports about the 6r100 having a clunk sound/feel. No resolution that I know of.

 

You having issues with yours h20?

 

I've noticed the clunk sound/feel mentioned above when reapplying gas and traveling at ~25mph and its in 4th gear. More like U-joint. My 2002 had similar issue but it had 125k vs 14k.
I have also noticed on rare occasion when shifting to reverse more noise than I would expect.

 

Where there's smoke, there's fire. I would be concerned. I had a '91 Ranger with 200K miles on it that did the clunk. Replaced u-joints and rebuilt the rear axle. That helped a bit but the clunk was still there. That left the transmission as the culprit. I knew I wasn't keeping the Ranger long term and opening a working but noisy transmission wasn't cost effective.

 

My 2018 has had the clunk since I drove it off the lot, 5k miles now. I wonder if they've fixed whatever is making that on the 19s?

 

Under what conditions do you get 'the clunk'?

 

Exactly like described in this thread:

When letting off the gas or suddenly re-applying it, frequently causes a "Clunk" to be heard and felt below the truck - best way to describe it is slop in the drive-line somewhere. Seems to be almost exclusively reported by those with 6.2/TorqShift-G.

 

Thanks for sharing the thread. I hadn't seen that one. It does seem related more to TorqShift-Gs but not exclusively. It almost seems related more to Sterling rears as there was a few F250 6.7s in the thread. They'd have 6R140 trannies but most likely have the Sterling rear vs the Dana rear.

 

I"m up to 30k with the 6.2 and have had that "clunk" since about 15k miles. Just noticed this past weekend my transmission case is leaking fluid so she's going into the shop in the next few days. No other problems than that.

 

18 4.30 with 6K miles and haven't noticed a clunk. I tried hard yesterday and nothing.

Easily the smoothest trans I've driven
