That reminds me, I still have a few wires to hook up on that shift controller, including the OFF light and the OD control switch. The new controller is pretty aggressive about locking the TC. That's good, this time of year.
At least half the year I'll be more concerned with getting it warm than cooling it. I think I'll want that loop through the radiator when it's -40.
It's an older transmission, no signs of damage, but the OFF light would flash intermittently, and then it would shift very hard. I figured the new...
I'm not sure yet what's plumbed in there. I'll need to put it back in the shop and trace those lines.
After I posted this, I found several threads with folks talking about running 100F above ambient. 155F is right in that ballpark.
I don't think it has a bypass - that's going to be a pipe...
I took my ambulance for a test drive with the new US Shift controller. I drove a few miles on flat ground, ambient temp around 50F, running empty so vehicle weight probably around 11,000 pounds, cruising about 50mph. The controller told me the torque converter was locked up must of the time I...
By the way, I got lucky on fleabay a while back and got a decent quality hydraulic crimper set used, with all the dies. I had been using a little hammer crimper that required laying the cable on the floor and pounding away with a hand sledge.
This was the first time I've used the hydraulic one...
I have some wire in stock I'm planning on using to make up new cables for the red truck. If I ever get that finished I'll be able to give the brown truck a rest. Someday.
The cables from engine block to battery- and between battery+ are 2/0, the cable from passenger side battery+ to starter is...
Those cables I thought were good weren't so good. I cut into the wire leading from the battery+ to the starter relay, and it was pretty cruddy. This may not have been the problem, but it was fixin' to be a problem.
So I redid the cable ends, and replaced the piddly wire from battery to starter...
My EVTM for the '89s arrived in the mail yesterday. I'm planning to look for the source of power in that, then try to find it on the truck. Odds are good something is corroded in there.
