Hey guys quick question..


I have a jakes 4l80e stg 3 that I purchased from a member here 1 1/2 years ago, he bought it new but ditched his build..

Fast forward to today, I started my car for the first time 2 days ago with the new tranny installed and it only has 2 minutes idle time and I shifted through the gears while I had my foot on the brake and turned the car off. Then refilled with fluid, it has about 14 qts in it to full mark.

Well my tcc solenoid wasn't getting power so I pulled the pan to look at it and noticed some metal flakes in the drain pan and some tiny black specs? Maybe gasket flakes?

Here's some pics of the drain pan and the pan itself

Did you flush your cooler?

It's a brand new cooler with new cooler lines..

Could be some tiny rubber from when I cut the AN lines?

Here's more pics of the pan

Really in the picture that is nothing. Sometimes its still hard to really get out every particle but new hot transmission fluid really flushes things out.

I agree, I never got it to operating temps. I felt the flakes.. It's dust, nothing big but just wanted to check to see if its common

Put a magnet in the pan like GM did.

Well the drain plug has a magnet on it, just wanted to know how much flakes/debris come out after a new tranny install

I don't see anything to be alarmed about.

One thing that I'm glad I was reminded of (since I'm writing some stuff for the website and customers today).
Even a new cooler needs to be flushed.

We sometimes see debris from new coolers when we flush them, sometimes WAY more than you would expect. I suspect they are soldered together and not thoroughly cleaned. I will add a line about this in our installation tips.

I'm not super alarmed, just curious!

What's the best method to flush the cooler lines out?

I cut the filter open a little and I see no metal

Put a magnet in there. Listen GM would of saved some money if there were no magnets in the transmissions and that little drain plug magnet is not enough. If its not wearing in your not using it!

You can use transmission flush that comes in an aerosol can. You can use brake-clean and compressed air. You can also use A/C flush and a pressurized canister.

Any flushing solvent and compressed air.

I like to flush both directions until clean. If the cooler has seen a serious failure, a new cooler would be advised.

Most transmission remanufacturers require a hot flush be performed for warranty purposes.

Also,
there is always going to be some debris from a new trans build.
Clutches will shed some friction material. I describe it as a "lint" like material.
New bushings will shed some non-magnetic sparkly material.
I also believe there is some welding slag material that often comes out of a new converter from the welding process.

Yes it was like a lint, it's a new converter as well..

I'll flush the cooler, add new fluid/filter..

After a few hundred miles I'll do another drain/filter change and see if it goes away

Jake hooked you up. Change the filter slap a magnet in there because parts do wear as you use them. Good to go!

Since your a magnet pro how do you install one in a cast aluminum pan..

I heard someone say to put one on the bottom of the filter?

JB weld it to the bottom. I have a neo magnet in mine.

I used a 2"x 2" sheet magnet, drilled a hole in the middle to fit over a foot of the filter and then epoxied it to the filter.

Hmm that sounds pretty easy, I'll have to try that
