Might as well provide a current update while I'm in here... I SHOULD be riding around right now enjoying this 80 degree in March day with my not quite done but back on the road 80. Instead I'm pilfering with things like interior and paint waiting to order parts Monday. During the drive to the alignment I had little to no power when easing on the throttle, shifts weren't happening at the right times, and they were pretty hard. Also I had an idle between 1600 and 2000 RPM. I've found a couple things this weekend. Simplest was the trans fluid was low. I had filled it on level ground in the garage, and had even drained some because it showed over filled on the stick. Even after running it through the gears a while (not moving). Just like the power steering though, it fooled me. Must have had some air in the system somewhere that didn't clear out until it took a real drive., I suspect the torque converter. I'm not sure I have even posted it in this thread, the tranny never left the truck, but I dropped the pan to replace shift solenoids and pulled and drained the torque converter while the engine was out. The initial drain of the TC may have been slightly less than intentional.

That improved the shifting somewhat, but it still wasn't good. Adjusted the trans to throttle cable for another incremental improvement, but still not good, and still have a high idle. At this point I suspect my nice, new, Toyota OEM throttle position sensor is bad. The spec at idle / closed is 2.3 KiloOhms "or less" across the idle circuit. I have 13.5 Ohms reliably as long as the sensor is anywhere before open. While that is "less than 2.3 KiloOhms", it doesn't seem right. I did find the old sensor I took off, but it gives me 33.6 KiloOhms for the same test, which is just, well, bad. With the TPS unplugged I get a nice ~600 RPM idle.
Speaking of the power steering and expensive new (or at least rebuilt) parts, I had a couple of nice puddles of Mobil DTE 24 in the garage floor Saturday morning. Looks like I am bleeding from the adjuster screw on top of the steering box. Sounds like a not uncommon problem after rebuild with both West Texas Offroad and Red Head Gear. This box was done by West Texas a few months before I started hearing less than great things about them (remember I have been working on this thing for a long time). Guess I'll order a new seal and nut with the new TPS and hope that takes care of it.
I really want to get this thing moving, local cars and coffee has an old 4X4 theme next weekend and I want to be there. No, I'm not kidding...
