For the last month my 80 has been shifting a little slower, I didn't think much of it since the 80s aren't known for their fast shifting, but yesterday, I put my car in park and left the AC running while I was waiting for someone. About 10 minutes of keeping the car in park the RPMs started jumping after being stable for the 10 minutes prior. After the RPMs had been jumping for about 30 seconds the car just died and the dashboard lit up like it usually does when it dies. I put the key back into the ignition instantly after it died and it started back again with no issues with RPM. I just checked my transmission fluid after letting the the car sit over night and the fluid read HOT despite not driving it over 16 hours ago. I attached below what the transmission dipstick read. I am a complete newb with this. Oil level and engine temps are fine. Any help would be greatly appreciated!!!!!!!!!!!!!!

Transmission is unrelated to the engine dying.

To properly check.your transmission fluid, you must drive it 10 miles or more to warm it up.

Then you check it with the engine running and with it in Drive. (wheels chocked or parking brake set or against a curb). Truck must be level.

What you are seeing is typical for cold transmission with engine off.

Thank you I was pretty sure the transmission wasn't related to the engine dying but just wanted to make sure.

If you drove it 10+ miles, stopped in DRIVE, pulled it, wiped it off, reinserted, pulled it and that's the result, I would say.you are one PINT low. Add the correct fluid (check owners manual), drive it, and check again.

It should be at the TOP hash mark, but not over it when it's correct and full.

Does it really need to be in drive? I am not doubting you I have just never been told this. It seems like a dangerous task for the factory to recommend.

You are correct. Toyota states in park.

See attached photo.

Every other vehicle I've owned is hot and idling in D with parking brake set.

Lets get back on track.

What year 80 series are we working with here? 93-94 have the A442F with a stand-alone transmission control module which you can jump for diagnostic codes and the 95-97 have the A343 which has the transmission control module integrated within the ECU.

I've always checked my fluid with the trans in Neutral, I thought this was the standard because that's what my other Japanese cars require but I did just look at the FSM and now realized I've been doing it wrong............................

I'm going to have to look into this for my '93. It's started acting oddly in the shift from 3rd to 4th.

FWIW, when my 95 exhibited a slow/early shift it was broken kickdown cable, not saying that your problem but worth looking at.
