I have been having an intermittent problem with my car. Some days it's runs great and other days in will go through the gears...1st, 2nd, 3rd and then will stay there, it doesn't shift into 4th. I thought it originally was a transmission issue so I had it replaced. The rebuilt transmission does the same thing. ?? It even will go in and out of 3rd and 4th sometimes. I took it to various repair shops and they can't find anything wrong. Could it be the computer ?

Hi reybob,

Thank you for the donation.

Transmission not upshifting to OD or intermittently working could be due to computer, 3-4 shift solenoid or wiring system.

Have you tried to retrieve for trouble codes?
Was the 3-4 solenoids tested?
