PPE Transmission Pan Install

Devil's advocate here...

 

Who says the dipstick is going to have the level correct?  GM didn't build it with one to begin with and engineered the pan to have the level set/check plug and the tube in the pan to the correct fluid level.  

 

The fact that even PPE engineered it to have a level set/check plug like the OEM plug also tells me that the plug is the most accurate measure.  

Well, the transmission pan has not changed for the 6L90 in a lot of years.  All they did was remove the dipstick for the post 2019 models trucks and replaced it with a plug.  So, adding a factory dipstick in place of the plug has no bearing on a means to check accurate fluid level.

 

PPE using the same plug set up as OEM makes perfect sense. If someone replaces the factory pan with their product, they would still need to ensure the method to check fluid level is adhered to (especially for those who don't have the dipstick).

 

In my case, I installed the dipstick prior to installing the PPE pan.  So, I was able to record the level on the dipstick prior to installing the PPE pan.  After installing PPE pan, I ensured the requisite amount of fluid was filled to match the recorded dipstick level.

I have a 22. It has the stock pan in it still. I just added the trans the and stick. 

 

 

So you have not verified via the stock level check plug if the dipstick has the correct measure point to it...

Nope. I’m just assuming it is filled correctly from the factory. And I put that dipstick in very early on and it registers the proper spot on the dipstick so that’s good enough for me.

That’s wild? So you think most people crawl under their new truck to check the transmission fluid level from the factory? To me that’s “wild” 

And upon the first fluid drop I’ll be able to see how much fluid drains out and cross reference that with the known amount that comes out and put that exact amount back in via the trans stick. Pretty easy stuff.

No.  What's wild is you didn't bother to verify if the level on the stick matched the level when using the check plug.

 

How do you know if the dipstick is actually indicating the correct level???

Because I added the trans dipstick to a new truck. So I’m assuming the fluid is already at the right level from the factory. And because no one has ever opened up my new truck that I got with 5mi on it, I would also assume that the fact it is showing full on my added transmission dipstick, that all is right. 
 

it would be different if I added this dipstick to an old truck that I didn’t buy brand new. Then I get what you’re saying.
