PPE Pan on a 2016 5.7 Hemi - 8HP70?

[tfeni52355]

I am considering changing the transmission oil pan on my 2016 Longhorn 5.7 Hemi with the ZF 8HP70 tranmission to a PPE pan. Some things I am concerned about are:

1) There have been some conflicting posts about whether or not the PPE pan can be installed without modifying the Y pipe for the exhaust. Is this true or not?

2) There was also a post about the fact that the extra fluid would take longer to heat and cool down due to the extra mass of the fluid in the pan. Should this be a concern?

Would like to get some input from someone who has made this modification and can provide their experiences.

I say go for it and report back! I agree with the conflicting posts but I have stumbled across someone who looked like it worked out fine for them. My bigger question, is the drain plug accessible? From the images it appears that it would be. This would allow for a fluid change without drop inbetween a full filter/fluid change interval.

Can't answer your questions, but use you tube to see how to refill with fluid. You have to us a Jack to level the trans or you will under fill. This will fry your trans. You can find more info on the synthetic oil thread, or you can just post a question in the thread.

I would contact PPE, unless it was designed prior to the 8 speed there should be no issues with clearance using the OEM downpipes.

Circulation speed to heat should not be a concern with this trans, their engineering team would certainly be aware in the PFMEA.

Another question might be what about the guys that have installed headers and have a different cross pipe. Will the pan clear or does the pipe have to come off? Some of those pipes are 3" and the newer ones are 3 1/2"

I was curious, so I looked up the PPE pan. $264.

Should clear Jay. I never had any issues with clearance with my 1 7/8" JBA's when i was using their cross over pipe unmodified.Had probably close to 3" of clearence between the pan and the JBA cross over

there is a pic in another thread showing no problem with fitment . look on the engine performance title.

And the answer is YES to both the clearance and drain plug location.

Hey. Has anyone ever wrapped the section of exhaust pipe, with a header wrap type of product, that runs under the transmission pan to prevent heat from that pipe heating the pan which would in turn elevate the trans fluid temp?

 

[Hookedup87]

Also, has anyone who has installed that pan noticed a cooler transmission temp due to the extra fluid and cooling fins on the pan?

I did. I used Heatshield Products Armor 170102

 

[Hookedup87]

Did it help? Notice a little cooler temps? I would imagine it must help somewhat right?

My long tube headers and complete exhaust system is header wrapped to my X pipe,life expectancy of the 3" maggy mufflers isn't great though,lol.I use the mufflers as a poor mans expansion chamber

I also installed the Revmax thermostat bypass kit at the same time so I can't say that the pan/extra fluid or the heat shield did anything for cooling, but I like to think it had too. I'm also running a 3k stall converter so YMMV.

This is gonna make me feel really old and out of touch......but......can someone please tell me Wtf YMMV means?

How do you like the Revmax thermostat bypass kit? What are your tranny temps with it? If anybody can make an 8 speed hot,it should be your truck,lol

I was seeing average temps around 165-170. I haven't run with the new engine yet.

Hurry up and get that thing installed,there's a few of us trying to live vicariously through you,lol

LOL trust me I want to!
Soon, within the next month or so for sure.
