***CAUTION*** I do my own stunts!
Figured I should update this thread.
Nothing terribly interesting to report.
I modified my modified oil system again.
Originally I had removed the factory oil filter and installed a remote oil filter adapter and added 2 BIG filters on a remote mount (on the inside of the passenger frame rail in front of the crossmember that goes under the oil pan) along with an aftermarket oil cooler out front.
Later on I upgraded to the Cold-Case all aluminum radiator that had an oil cooler built in but I didn't hook it up originally.
Fast forward to the present and I had, what I thought was a small leak at one of the hydraulic line fittings at the remote filter assembly. So I decided I would change out all the oil lines and add the radiator oil cooler into the mix while I was at it.
I decided to ditch the spin on remote filter adapter I had installed at the factory filter location and use the "Factory" oil cooler lines that bolt to the pan right above the filter.
I say factory because I bought the oil cooler lines and then cut the crimps where the rubber meets the aluminum tube and attached my own rubber hoses to go where I needed them to and to hopefully avoid the leaks at those junctions that everyone seems to complain about eventually.
My oil now goes through the filter at the original location, out to the 2 oversized remote mount filters, through the oil cooler in the radiator then through the aftermarket oil cooler out front and back to the engine.
3 filters and 2 oil coolers make for about a 10 quart oil change, but I also run 15k mile OCIs, while sampling oil and sending it to Blackstone for testing, without issue.
The Burb now has 333,000 miles on the original engine and transmission... until a few days ago.
I thought I had an oil leak at the rear of the oil pan but long story short it turned out to be the rear main seal leaking.
I hate leaks and I didn't have the time or place to really do the job so I farmed it out to a guy that rebuilds transmissions.
I was very conflicted about having a perfectly good transmission, with zero issues, rebuilt... but I also couldn't, in good conscience, put a transmission with 300k+ miles back in without rebuilding and upgrading it while it was already out for the rear main replacement.
The guy who Rebuilt it confirmed my suspicions and said that the transmission looked amazing inside and that the frictions and steels still looked basically new.
Oh well, I have peace of mind knowing that it is ready to go another 300k+ miles.
I also have a new converter, a Transgo HD2 "Big Box" shift kit, as well as Corvette servos installed with a Kevlar band and frictions.
Details of the shift kit...
transgo.com
I have been out of town for work alot so I haven't had an opportunity to drive it since the rebuild but my oldest son says it shifts amazing, firm, fast, and crisp.
I am not certain how much of that is due to the tune I already had combined with the shift kit but I think I will be quite happy.
And the best part is I no longer have an oil leak, did I mention I hate leaks?

As a follow up to my previous post about the transmission rebuild/shift kit install. The truck definitely shifts great, super fast and the truck seems a little faster over all.
Also, I followed @iamdub 's lead and bought and installed a physical ethanol content sensor on the Burb. I haven't really had any issues out of it since installing the correct O2 sensors, (previously I was having issues with it calculating the ethanol content way to high), however I can tell you that I checked the ethanol % before turning the physical sensor on in HP tuners and it was reading 14.9% and after installing the physical sensor, and turning it on in the tune, it immediately corrected to 9.4%.
I know it probably won't amount to a tremendous savings in fuel economy but it would have to help since it is getting a more accurate reading and constantly updating instead of only recalculation after a fill up.
According to the research I did the difference in fuel mileage between E10 and E15 is only about 1-2%, but that still adds up over time I guess so I will call that a win.
I didn't take any pics as this was already pretty well documented by Dub.
