Applications to find an A-500?

Huh? The automatic you want to shift manually?
Off hand, I don't remember the first year they came out. It was in the 90's. The big thing here any how is you want to have a non lock up.
Do your home work before purchasing.
I myself would like to get there as well for my '79 Magnum. When the time comes, I'll be looking around the net to see how has them the way I want it.
Sorry to say that from here, my knowledge well is only a Dixie cup in size & 90% empty.
I've been running an A-833 pretty much my whole life. Any automatics have received little if anything over stock.

I just like to row my own boat. And with vigor! LMAO
