The only solenoid in the A440F (91/92 FJ80) is for cruise control unlocking of the torque converter in certain conditions. In reality it does nothing of any consequence and will not effect shifting as it is 100% hydraulic.
The setting of the...

Only the 93 -94 US spec has the A442F which is electronically controlled using solenoids. The 91 -92 models use the A440 which is hydraulicaly controlled, no solenoids.
Black exhaust smoke is usually unburnt fuel.
Since this happens when the engine is under load, I would suggest looking for wiring issues.
With the motor under load, it will shift on the mounts possibly grounding out a set of injectors (the 3FE...
You are all spoiled by modern vehicles. Back in 1994, this was state of the art, and plenty fast. I'm plenty happy with how mine work and they're completely stock.
Runs are a big part of it, though if your regulator and motor are worn out, they make their own contribution. I'm also sure he's right about low voltage getting to the motors - 30 years of corrosion makes a difference. That said, for $300, I can...
I’ve actually reached out and been in contact with them. They are going to help me square it away.
I also talked to my local 4x4 shop. He recommends the Napa alternator. Lifetime warranty, and good quality vs other parts stores.
Looking at the website, it appears that it plugs into the POWER MAIN RELAY socket as it is shown mounted in the left kick panel. So everything downstream will be getting the boosted voltage (sunroof and widows). As you stated, it's not going to...
It appears to be a 12V to 15V 30A DC to DC Step Up Regulator: Example $65.54
The extra $229 is for the bracket, relay, and relay extension.
Amps will stay the same, but voltage increases by a couple of volts = increased power. P = VI.
The...
You have an 80 amp alternator with an external fan behind the pulley.
Those units are not easily serviceable like the newer units unless you have significant soldering experience.
I would either retrofit a rebuilt 90 amp unit using the...
"The Window Rocket replaces the power window relay. Using a 40 amp relay to pass the necessary current, then boosting the voltage several volts with a special module ensuring the window motors get the 14 volts they were designed to run on."
