95' Intrepid Tranny issues!

[IntrepidHelp!]

Hello all,

I have a '95 intrepid 3.3liter. My tranny sometimes, not all the time, get stuck in second gear and I have to restart the car again. It seems like after the car is driven around for awhile. Also, all the time, in reverse, it grinds when I first step on the gas. One of the chain tranny places says just rebuild it and mentioned the fluid is burnt. The fluid is a light brown and there is extra fluid that I put in awhile ago with an additive which is causing an overflow I think. Realizing after the fact Dodge tranny's are sesitive to certain fluids and all additives, should I get it all flushed or just changed? Can this just be the problem, to much wrong fluid and its time for a fliter and fluid change?

Thanks in advance :D

I've read many statements that fluid type cause the problem. I've tried to change fluids, use of special addictions. In some way it helped for a while(500 miles) but problem was always coming back again. Rebuilding the tranny solved the problem. The auto shop used the regular tran fluid, and when I expressed my concerns they laughed at me. In fact they were right - I'm running on my rebuild tranny for more than 45K miles now without any issues. The cost ~$1700.
