The thing STALLS on me, intermittently, when I stop. Usually around 40% of the time (estimate)
Here's what happens:
I'm driving along all fine and good, until I have to do a Stop and Go, like at a stop sign, or a red light. When I'm almost at "stopped", it seems like the transmission wants to keep pushing the truck, and won't allow the truck to just idle, like normal, and then it SHUDDERS and STALLS! It's almost exactly what would happen if it was a manual transmission and trying to come to a stop, in gear, and not using the clutch. Starts shuddering, RPMs drop, and she stalls.
Once this happens, I have to put the truck into Neutral or Park, turn the ignition key all the way to off, then start the truck again. It starts and I'm able, then, to put it into drive and carry on. It's like the key turning off, then on again, kinda "Resets" whatever is wrong.
More info: I've tried shifting into Neutral as I'm nearing the stop when it feels like she's gonna stall... So I COAST to a stop. That will recover the RPMs and allow me to stop with the truck idling, but if I then put it back into gear, the stall process continues from where it was before going to neutral. So, even when I coast to a stop in neutral, I can't go again unless I turn the key off, then restart the engine.
Also, I've noticed that it doesn't seem to be affected at all in REVERSE gear.... just a DRIVE gear.
Also, I've tried hitting the O/D OFF button. No effect.
I've been doing a LOT of reading. Lots of stuff about how the Ranger uses a series of sensors that feed a main computer unit that controls stuff, like this IAC thing that is there to control idle and idle rate.
The thing that has my biggest interest is the Torque Converter Clutch. Have a look at the article in this link:
https://www.freeasestudyguides.com/automatic-transmission-tcc-torque-converter-clutch.html
Where it discusses about what it does, it almost perfectly describes what happens to me. It seems to be that it's supposed to put the transmission into a kind of Temporary Neutral and that if it doesn't kick in, it'll force the vehicle to stall.
A buddy of mine is a mechanic who works from his garage at home. He and I went out for a test drive today and, guess what... it WOULDN'T STALL! Crazy. (Normally, in the drive we did, I'd have expected it to stall at least 3 or 4 times!) Put the code reader on it... no codes except one that identified a startup problem. He thinks that's a coil pack problem. Tomorrow, I'm getting new plugs, wires, and coil pack (and fuel filter). Also, he's gonna drain the tranny fluid and replace, along with a new filter. The fluid is pretty dirty, but didn't smell burnt, so happy about that. He suggests to do these things (which needed doing anyway) and that this "MAY" also fix the stalling problem, thinking that the current tranny fluid may have lost the required properties to make the Torque converter clutch work properly, and hoping the new fluid might fix it. If it doesn't, then he figures the Torque Converter (clutch) is the next thing to look at, but to do this first. From our little drive, he's also satisfied that the transmission, itself, feels and acts healthy.
Anyway, I think that's about everything I can think of to describe it to you. Have a good ponder and, please, feel free to offer any suggestions, places to look, ideas.... whatever. Any questions, also, please ask. I'll answer whatever I can.
