If you want to consider rebuilding it yourself check the details and links in the threads below. I’m pretty sure at least one of the ASTG manuals mentioned in there is posted here on OB I thought there were links in here to the other one as well but I can’t find those posts right now. Most of the “upgrades” folks did back in the day became standard parts in the 4R100 a few years later. Which makes them much easier to come by. In fact there are guys out there that have taken salvage yard 4R100s and swapped the front pump and solenoid packs with E4OD units and been good to go. You can still blow your life savings on upgrades but my experience has been that adding extra standard clutches in the suggested drums, swapping the aluminum planetaries for the 4r100 steel equivalents, updating the center support and its snap ring, using a hardened sunshell, making sure your pump halves aren’t warped and upgrading the pressure regulator and something else, and then working over the valve body with your choice of transgo or sonnex kits, making sure the surface of the case and valve body are flat and not leaking, installing a good and large cooler and putting a quality triple disk converter in front of it will make it go at least another 100k. I’ve got about 140k on my DIY rebuild now with quite a few reasonably heavy trailer trips and lots of in town driving and it hasn’t given me a bit of trouble yet. Read the engineering documents from sonnex and transgo about each of their offerings. They each designed their products to solve problems in slightly different ways so mixing and matching products from each doesn’t always produce the best results.

Well, I got around to draining the fluid and pulling the pan today. From what I can see the fluid looks good and red, does not smell burnt. The valve body looks surprisingly clean. The solenoid pack has an etched number on it and 06, not factory, I suspect it was done by the last shop that overhauled the tranny in 2006. Just a guess. I am curios what year the trans might be, lots of factory stamped numbers on the valve boy parts, I few look like they could be a date.
The bad is there is some metal filings stuck to the magnet, and a few small pieces of metal that appear to be parts of a broken spring about a quarter inch in diameter.
