Hey guys...

I just picked up a 4l80e from a 97' k3500... Its going behind a 4bt cummins in my 03' tahoe.

Anyways... gave $350 for the trans and transfercase.. guy said it had around 100k on the clock and drove fine...

Fluid was a little dirty but not burnt... the filter was aftermarket so it had been serviced... and there was very little material in the pan... everything looked great.

When I wiped the magnet in the pan off... I found a little sliver of metal... looks like a piece of a small snap ring... it was thin and flat... 1/16" (probably smaller)or so wide... maybe a 1/4" long.. rounded like the ear of a small snap ring.

So.. 4l80e gurus... where could this have come from? I was planning on just running the trans as is but I dont want to cause damage... will most likely go through it now.. but wanted an idea of where the piece could have come from.

Thanks guys

Hmmm not sure but sounds like an interesting project you have there !

 

It has been a fun project... it runs and drives now but has eaten two stock 4L60Es in the last few thousand miles... number 2 is on its way out (I had the trannies so it wasnt a cost thing... but I'm tired of the truck being unreliable)

Here are a couple pics of the truck... its not finished... still have a lot of detail stuff to get finished... but want to get the major stuff out of the way first.









Got tired of averaging 11mpg... With a junk trans... I've managed to average mid teens... once the 80e done and in... I should be able to get it into the high teens/low 20s pretty easily. A smaller compound turbo setup is also in the works... (hx30/hx35 or 40).. basically will make for instant boost of idle and 35-40ish psi up top with the 35... more so with the 40.

Anyways... if anyone can help... please do.

Thanks guys
