Thanks. I got only 100k on my 05. Lets hope it gets to 260k in one piece.

How many miles when it failed?

149k. I bought the truck in December of 2015 to pull our travel trailer and it had done a lot of trailer towing in the 8 months before the failure. Plus the 4L60E has some weak points, which the rebuild fixed (basically cheap parts that they put in at the factory that can be replaced with better parts if/when it fails.)

The "good" news was that it "failed safe", that is, I lost 3 and 4 but 1, 2 and R all worked so I was able to "limp" home in 2nd gear. Not fun (it went out in Kremmling on the way home from Steamboat Lake and I had the wife, dog, trailer, 2 kayaks and a whole bunch of camping gear on board!) but it beats having to be towed.

These old GMT 800 trucks were fairly reliable but they do have known weaknesses. So far I've experienced just about all of them (besides the transmission, there were the stepper motors on the instrument cluster and the intake manifold gasket, intermittent 4wd actuator motor issues, etc) except for the fuel pump, and I'm seriously contemplating replacing the fuel pump pre-emptively. Oh, the alternator went out (again, on a camping trip) but due to the fact that I installed a 2nd battery I made it home with no issues and replacing the alternator took me literally 30 minutes on a Sunday afternoon (nice thing about Chevy trucks, you can find parts for them EVERYWHERE.)

Please keep me updated on the health of the rebuild. I've got 178K on my 02 Ex. The 4R100 has been well maintained, but I know that a rebuild will be in my future based on the towing I do. I'd bring it to Denver for a quality job. Was considering sending the tranny to the guys at A1 Transmission in GA when the time came, but would rather spend my $ in state if possible.

Will do. Took it to the mountains yesterday, did great. I feel like I need to put a transmission temp gauge on it due to towing.

You may be able to use a Scangauge II to show trans fluid temperature. It worked on both of my 4runners and it works on my Suburban.

Much easier than installing a gauge - just plug it into the OBD-II port. There are other OBD-II port readers that will show trans temp as well. Some of them will send the info to your smartphone.

FORSCAN and a cheap wifi OBD2 adapter.
Not the prettiest app, but is the best diag/service scanner for a Ford and a phone or computer without getting into the high dollar mechanic scan tools. (PC version can even run some service procedures)

The cheap WiFi odb2 scanners don't work on my f250. Diesels need other units.

After shopping for a month I ended up buying my pillar 4 Guage pod on amazon from glowshift. Best deal and came with all the install fittings. If you want to look at it and the two small mods I had to do just let me know.

This should work, I use Torque Pro and a ScanTool 427201 OBDLink LX Bluetooth (on a cheapo tablet) to keep track of tranny temps and a lot of other info.
