So from what I've gathered, if I don't have external plug for a lock up solenoid, I don't have a lock up trans?
Just wanna make sure, thinking about putting a new torque converter in while I have my engine out.
92 Spirit 2.5 NA 3 speed, the only plug I see going to trans is neutral safety switch.

Should have a lock up with electrical connector beside the trans dip stick.

Even Turbo cars got a lockup by 1991.

Possibly an older Turbo unit??

Thanks

Ok took a good 2nd look at my trans. It DOES have a lock up solenoid :(
Does this mean I'm stuck buying an almost double the price lock up converter???
What are the advantages and disadvantages for either???

Lock up and non lock up converters don't directly swap so you're stuck with what you have unless you want to change input, pump, valve body etc.

Differences are slightly lower stall speed and reduced cruising RPM.

Lockup stall is about 22-2400 RPM where a 2.2 Turbo stalls to about 3200 RPM per Chrysler service manual.

Disadvantage is the lockup part of the converter can slip when under high power.

Unplugging the connector prevents lockup if for some reason you don't want the lockup to function.

Overall the lockup converter is a good unit, especially if you do any highway driving, reduces Engine speed approx. 3-400 RPM when locked.

Thanks
