twalls Posted September 2, 2011 Report Share Posted September 2, 2011 Recently had transmission rebuilt by a reputable shop. However, now when going down the freeway and signal to change lanes, it drops in and out of OD with the turn signal. I am getting a pretty good voltage drop when the turn signals are on and I am assuming that this is interfering with the temp signal for the OD but not 100% sure. I have replace and upgraded the alternator to get a stronger signal but not enough to eliminate the problem. Has anyone seen this before or have an idea where to start looking. I think it may be a grounding issue bu not sure of that either. Link to comment Share on other sites More sharing options...
89PalermoSHP Posted September 3, 2011 Report Share Posted September 3, 2011 First place to start is removing the battery and checking/cleaning every connection down in that corner. Pay extra attention to the fusible link box. Take all of the leads out and get them clean and be sure they aren't burnt. Link to comment Share on other sites More sharing options...
Shelby Posted September 22, 2011 Report Share Posted September 22, 2011 default for our 4 spd auto is OD when power is lost to the relay or swt , so shifting in and out of OD may be a loose wire or bad swt Link to comment Share on other sites More sharing options...
