Revmax spin on filter adapter 68RFE

[Noneck]

Just wanted to share my recent experience with 2 screw on filter adapters I attempted to install along with my Revmax ultra low stall convertor, valve body and billet flex plate.
Those things have 2 different threads on each end. I tried to explain that to the guy at Revmax but I don't think he was getting it. I asked him if they had the same threads or different threads and he didn't know. (Which kind of surprised me honestly since He said he gets a dozen calls a week about these not fitting. ) He said some are just tight based on what vendor supplies the machined transmission case to Ram. I call B.S.. They aren't tight, they are entirey different threads. If I installed the adapter into my transmission using the end supposed to go into the filter, it threaded right in. If I spun it around it would not screw into the trans casing. Obviously 2 different thread pitches. I initially thought it wouldn't thread in due to a a burr I found on one of the first threads. (Which surprised me as well and not in a good way.) So I tried to clean up the burr with a little file. Still no go. Then of course I spun it around and realized it had different threads. Revmax sent a replacement very quickly which unfortunately had the same results.
So if they get this complaint all the time, why do they not know if the threads are different? Is it different year trucks that have different threads? The fix seems pretty simple. Make another adapter with identical threads on each end and problem solved. If someone calls and says the adapter doesn't fit, send the other one which I'm assuming is normal pipe threads and probably a 1 minute programming change to the CNC machine. No way am I going to strip out my casing for a $29 part!

Definitely good to know for those of us still planning to make the change. I will said before the price is a bit high. Even if it is made from billet
If the threads aren't cut right and unusable the cost outweighs any true value

Wonder if the other companies selling them have the same issue or if they use a different supplier

I assumed they were made in house by Revmax. Don't know who else makes them but of course now I'm slightly nervous about installing the factory plastic one as I see how it could be a huge problem if it cracks.

Transtar sells them to. I'm not sure if they make them or not though

Learning that Revmax doesn't they all may be buying from the same place. And might be from China or Taiwan. Somewhere in Asia anyway to save a ton of money

The guy I spoke to a Revmax said he'd have to talk to his engineers to find out if the threads were different, leading me to believe they were made in house but anything is possible.

I'll be watching for an update

I've got one on my truck...I must have gotten the correct side threaded in the first time because I had no issues. Curious to find out the outcome of this.

My suspicion is that there are 2 (or more maybe?) thread pitches in the transmissions. That's the only thing that made sense. The threads on mine were nowhere close to going in. Unless I flipped it over and then the filter wouldn't screw on.

I wonder if something changed between 2012 and 2013?

Certainly wouldn't surprise me.
