Hello, I'm Danny.

The first thing you should check is the transmission fluid level and condition. Make sure the fluid level is within the proper fill range and the fluid condition is not burnt or dark brown in color. Here are a few tutorials for automatic transmissions for service and repair:

Next let's run the codes to see if any are stored:

It sounds like the first gear shift solenoid is stuck and not working. Please go over these guides and get back to us.

Conversation Summary

A 1991 Dodge Stealth RT automatic with 86,000 miles will not upshift or downshift and appears stuck in high gear, with very slow takeoff until about 45 mph. Manual selection of 2nd or low also produces no gear change. The expert advised checking fluid level and condition, retrieving trouble codes, and investigating a possibly stuck first gear shift solenoid.
