Engine/Transmission (1994 - 1998) Trans coming out of lock on left turns

[Matt S]

Has anyone had a problem with the auto transmission coming out of OD lock on left hand turns? This is on a 95. It happens at any speed and corner to the left.

How do you get it to go back into OD? Does the OD off button light up when this happens?

 

[Matt S]

It just temporarily comes out of lock and then back in. No light or downshift to third. It just shifts back.

This would appear to be an intermittent electrical problem unless something inside the transmission is loose.

The cable that provides overdrive and torque converter voltage runs from the PCM to the transmission. It breaks out of the main harness that runs across the firewall right above the engine and follows the hump back to the transmission. Check the wiring and its connection where the cable plugs into the transmission. Don't confuse it with the start interlock.

The one you want is oval in shape and comes down from above and plugs into a vertical receptacle.

The interlock plug is round an plugs in horizontally.

Add about a quart of fluid and see if it goes away.

My Jeep does that only it locks up and only on right hand turns.
