Absolutely not dude! Don't do it! ALWAYS and ONLY use Mopar ATF-3 or 4 Type 7176. You may also want to check with a Chrysler/Dodge dealership to see if you can use Mopar Type 9602, which is now used as a factory fill in for your first gen trep.
Dexron even Dexron III does not meet the requirements and specifications of the Mopar ATF for most Dodge/Chrsyler/Plymouth vehicles, especially the Chrysler Ultradrive type transmissions Dodge Intrepids and other Chrysler Corporation vehicles have.
My 1995 Intrepid: I topped my Tranny fluid off with Dexron just once, only a little and my tranny soon after started to fail then the seals were going.
My mother in 1997 law's Chrysler Town & Country.... She used to take it to those quick lube places that would top off her tranny fluid with that kind of stuff and soon after her tranny began to slip, shift rough and the seals began to go.
The Chrysler Ultradrive transmission has had many problems since it's introduction in the 80's. There have been many changes to try and correct these issues, updated fluids, TCM (Transmission Control Module) updates and such to try and deal with the problems. I would play it safe with this and even use the Type 9602 if it is cool to use with a first gen trep otherwise go with the Type 7176.
It's up to you, but that's what I know and hopefully some of that info helps!
Take Care! Trep lightly!
