Good Day to you All.

I have a 1991 Honda Accord LX 2dr Coupe. Automatic transmission.

The transmission fluid looks OK and smells OK. It is filled to the proper level and having no issues with the transmission.

I have had the car 3 years and only put about 18,000 miles on it.

I'm the second owner

First owner drove it a lot more then I do. So total mileage is around 256,000.

Car runs and drives great. Last oil change I went full synthetic on the engine oil. I thought I would give it a try.

I believe the transmission fluid was last changed about 40,000 miles ago.

I'm thinking about changing it. I have a pump that connects to a drill so I just put a hose down the "dip stick" fill tube and suck out as much as I can get.

Then fill with new fluid. I know some old fluid gets left behind.

What transmission fluid should I use? What about dinosaur oil, or full synthetic, or synthetic blend?

How much does it hold when bone dry?

I know to check fluid level the oil needs to come up to temperature. But what about when draining it?

I can get oil locally from Walmart, AutoZone, or O'Reilly's. Other than a one location Independence store that's it for auto parts around here.

Honda dealer is 120 mile round trip.

As always I thank for your response and help.
