Help ID'ing this 4L80e?
Help ID'ing this 4L80e? Besides the fact it's dirty!
I know there's small nuances different between the years, just wondering if those with a sharp eye had any info on it. I was told it was behind a SBC in a "street rod" - but given the level of dust on it, maybe it was a street rod in need of a restoration.
I had read the "earlier years" had the cooling lines on the side?

IIRC Better Cooling/Lubrication. But 2000+ Years had stronger hard parts etc... That's what you really want just. Add a TransGo and have a pretty damn strong trans for just a shift kit.

Actually the early style units have a better OD sprag design, and all the" improvements" didn't seem to help from what I've seen tearing down hundreds of cores.
I don't have a problem using any year model core, on big power builds I always use the early OD parts even on a late unit.
The improvements GM did seem like a good idea but in practical application I haven't seen any real difference.

I agree with this statement the only issue I have seen is on the first or second years of this unit. The OD planet in some cases does not have any lube slots in the planets spline area. Also I ran into an issue with the input shaft not fitting into the later assemblies. For what I could tell the first year of shaft and planet assemblies were just a bit different and I had an issue with getting the snap ring on when swaping stuff around. I would make sure to use an OD planet with at least two slots in the planet for any unit in my opinion. Vince
