why are dodge transmissions labeled as crap(no offence)

I wish is was as simple as using the correct fluid. We are a Dodge dealer and used at that time the type 3+ fluid. That wasn't the issue. Mostly it was Electronic. We went through so many updated trans controllers I lost count. The computers would tell the trans to do foul things. They'd come in in limp-in and burned up half the time. But you are correct that you had to use the correct fluid or cause permanent damage. Mostly with any transmission; watch the heat, keep the fluid fresh and clean and the trans will last a long time.
