So when the truck is cold, sometimes the motor will stumble and/or stall. It seems to be idling fine and has lots of power. I think it may be related to the trans as it takes a few seconds after being in neutral for the trans to move the truck. It used to be worse. I would get a shudder and take a long time to get into gear before. I changed the fluid/filter and it seemed to get better - but the old fluid and filter were clean. The it was good for a while, but started slipping again. This time the fluid was low. Like 3 quarts. The truck only has 80,000 miles on it, and I see no leaks and notice no smoke as if it was getting sucked into the motor or something weird.

I added fluid and it got better, but still is slow to get into gear and stalls. But is still better than when the problem first appeared. I am scratching my head on this.


I forgot to add - the stalling is when I come to a stop. Not when I start the car or when it's idling or driving.

Is it a 5.7 Hemi with a 45RFE trans ? Ron

that trans is known for cracks in the trans filter that make it loose pressure thus causing slow performance and stalling.
Aftermarket filters are even worse.

Not so much cracking, although that has happened, the backpressure has been shown to actually split the main filter, (there are 2 in the pan),the filters tend to come loose where they are pushed up into the pump. A 125 filter seal will help hold the filter much better than a stock OE seal.
If the filter is sucking air, it cannot push the converter clutch off the lid and will drag/stall the engine.

So sorry for getting back to you guys late,

I got slammed with work and family being sick.

It is a 5.7 Hemi and, I think, a 45RFE (It's been a while since I changed the fluid and I remember being unsure of which trans it was until I pulled the pan). I can't believe I didn't put that in the post!

What is a 125 filter seal? Is this a GM seal? I read in another thread about some GM filter or seal or something like that, but I can't find the thread.

Is this the seal?:

What filters/seal do you guys recommend?

Again, thanks for the answers and sorry for the late reply.

OK.

I found the post buried many pages down.

I will try the 125 filter seal and see if that helps.

Thank you guys!

For anyone else out there having issues, I found this youtube video talking about the filter. A commenter also brings up the 125 seal.
