Well it looks like this after 68000km The Valve Body didnt have any issues.

Il be doing mine again at 120xxxkm.

Thanks for tons of great info. I have a question about the trans service. What mileage interval do you recommed? Presume no towing, generally easy driving.

ZF reconmends between 50,000 and 80,000 miles or 8 years to service the 8 speed

Thanks for tons of great info. I have a question about the trans service. What mileage interval do you recommed? Presume no towing, generally easy driving.

I believe manufacturer's (ZF) current spec is 90K for initial service, normal driving or in the 50-75K mile range for "severe duty" (offroad, towing, racing or "sporty" driving). I personally believe that fluid changes are cheap preventative maintenance and I did mine early. I've done 2 drain/refills in 86K miles. The first time I used a Mopar OEM pan/filter unit. The 2nd time I found a retailer that had a ZF branded unit and that's what I used.

As stated in this thread, you'll get a lot of different answers and "reasons why" - these are just the thresholds that I've decided to use. On that note, based on my learnings/experience, I would not recommend going beyond a drain and refill as some do. Replacing ALL of your fluid (e.g. "flushing") is not a good idea in most cases. Gradual change is better tolerated by transmissions vs. "change it all at once". There is some science/mechanics behind that thought process and you can read about it via an internet search if interested. Some opt to drain/replace a quart of transmission fluid at every engine oil change interval. That just seems like extra work, but it works for some folks. I will keep my subsequent fluid and pan/filter changes around the 30K mark.

Hope that helps and answers your inquiry.

What was the purpose of the tear-down? Just inspecting?

What was the purpose of the tear-down?

I installed the PPE Pan and Sonnax Zip Kit when I did my 8 speed swap.

Anyone who says this is a lifetime fluid is full of sh1te ! Same goes for the fluid. Looking forward to see how the Maxlife fluid will look in 60xxx km

I've looked at that Sonnax kit. How was the install? Fairly straight forward?

65RFE to 8HP70 Swap , Lifted Truck Edition!

I used this thread to get me started https://www.ramforum.com/threads/8-speed-swap.180898/ My cost breakdown, And parts list. in Canadian Pesos! - I already have HP tuners ( not sure why anyone wouldn't ;)) - Im lifted 6.5" in the rear, so there's zero reason to get the 8 speed rear drive...

Just completed a 3700 mile trip across a few states. Running mostly interstate or state highways, 65-75mph, mixed rolling hills and mountains, I averaged 22.6 mpg over those miles. I feel that's pretty good for a V-6 powered full-sized truck. Temps ranged from mid-teens to 65 degrees. Truck ran a consistent 195-197 degrees coolant (hit 205 a couple of times pulling grades and higher RPMs), 185-192 degrees transmission, and similar oil temps. The computer said I had consumed 39% of the oil life (for whatever that's worth to you, or 61% remaining).
