The trans. may not shift out of 1st gear for several drive times in a row , then it may not occur for several weeks. I have had to stop on the side of the road and turn it off for atleast 2 min. , then restart it, which will allow it to shift normal. I have had times when it wont reset for several hours after the drive time.I never get a diagnosis light,/ code.I changed the trans. with a working one, and It made no difference. then i changed the trans. control module, and it made no difference. thanks to whom ever can shed some light on this problem.
at random times, the transmission will not shift out of 1st gear. on 1995 Mitsubishi Eclipse

Your Transmission system needs to be re-inspected, we at RepairPal have put together a Diagnostic Sheet that will help you or your shop to organize this inspection process. You need to do a LIVE data scan of the transmission and engine while driving and look at the input and output speed sensors and all the engine sensors, not just 'code read' . It may be a wiring harness problem and a live data scan will help with this. http://repairpal.com/automatic-transmission-diagnosis
