Just to further clarify the neutral cable for anyone else that may stumble upon this thread. If you're not going to use a cable and just rely on a screwdriver or pry bar for activating neutral, make sure you have some heavy duty zip ties as the lever does not stay in neutral once put into neutral, it springs back to park. You would need to activate neutral, tighten the zip ties and then you can keep the pre-sized/tightened zip tie setup and lever of choice in your vehicle, should you ever need it.

Great thread guys, appreciate all the knowledge transfer here. I finally dropped a new motor in my 2013 Ram 1500 2WD Tradesman, secured my 8HP70, driveshaft and shifter. Still need to source the misc cables and build a harness as my truck doesn't have the necessary wiring waiting for me. However, I do have a full 2022 engine wiring harness that I can grab the tranny connectors off of. Just need to fab up a drive shaft bearing support or find one in a wrecking yard. Have my HP Tuner ready to go, already played with it to complete my MDS delete on the new 5.7. Just need to find an OEM 8HP70 tune and hopefully will be swapping the tranny in by Spring.

I'm curious about the improved drive-ability, is it overall snappiness that improves or just the shifts? The 6-speed is leaving a lot to be desired as far as general peppiness with a new crate motor in front of it.

It's a night and day difference especially if you get it tuned by flying Ryan and add the zip kit :favorites13:

The way this transmission holds gears is incredible. I only got my truck up to 185 km and it was still pulling. :driver: but being on a 6" lift on 37s made it scary AF. :anitoof:

The 8HP70 always seems to know what gear is should be in, and always has another gear (or four) in reserve when you give it gas...if you want more acceleration.

Gear shifts are pretty much seamless. There is no drop in power during a gear change due to how the next gear solonods are engaged before the prior gears are released.

Check out my swap thread, I talk a bit about how much better the overall drivability is as well. I have a light throttle acceleration video that will be eye opening.

I know there's been a couple 2500's with the 8 speed swap over on the hi-po Ram pages on facebook,but i'm not sure anybody on here has done the swap into a 2500

Any chance you could share a link to the groups/posts here? I've yet to see any tech/info on anyone swapping into a 2500.

Anyone tried using one of these instead of the rotary dial yet?



Ken, neither of those links works on my laptop.

When I mouse over, they both show 'rover' preceding and following http://ebay.com and the https is missing the s for ebay.



And, the URL is enormously long.

I removed the http so it would display as text.

//rover/ebay.com/rover/1/711-53200-19255-0/1?pub=sportscardforum&toolid=10001&campid=5338805061&customid=&mpt=7969626&mpre=https%3A%2F%2Fwww.ebay.com%2Fitm%2F226656344803%3Fmkcid%3D16%26mkevt%3D1%26mkrid%3D711-127632-2357-0%26ssspo%3D5JRzZL5PRiu%26sssrc%3D4429486%26ssuid%3DytI2ZkxnS2q%26var%3D%26widget_ver%3Dartemis%26media%3DCOPY

It's the 8hp70 shift lever for the 2020+ Dodge Durango's. The wife's Durango has one.

It seems to also be used on Chargers, Challengers, 300s, and others

View attachment 565344

I could see the picture in the link and wanted to check it out. :cool:

I could only find a 2018 shifter on ebay, I don't know if it's the same or compatible.
The link is also crazy long, but it does work for me.

I take that back. It did work, now it doesn't and I noticed the addition of 'rover' in the URL again. It must be the RF site is mishandling this URL.

I'll try a few more tests and report the fault. :cool:

I reported a fault for the mishandling of the ebay links above.
I would be surprised if it isn't happening elsewhere on the RF site, too.

Every eBay link I've clicked on Ramforum has done that, for the last few months.

I just assumed something was going on with eBay.
