barberben Posted June 22, 2005 Report Share Posted June 22, 2005 Can shift solenoids malfunction intermittently? Could they be bad and not throw a code? Link to comment Share on other sites More sharing options...

Ranger Posted June 23, 2005 Report Share Posted June 23, 2005 My guess is no to both questions. Link to comment Share on other sites More sharing options...
acklac7 Posted June 23, 2005 Report Share Posted June 23, 2005 I believe someone else had solenoid conditions with a 92' (4t60E?)....And didn't throw any codes....could be wrong A.J. Link to comment Share on other sites More sharing options...
adallak Posted June 23, 2005 Report Share Posted June 23, 2005 Perhaps you need to wait and watch. Sooner or later some codes will show up and make it easier to diagnose the problem. The saddest thing in life is wasted talent Link to comment Share on other sites More sharing options...
barberben Posted June 28, 2005 Author Report Share Posted June 28, 2005 Still no codes. Is there a way to test the solenoids without dropping the pan? Also, could any combination of solenoid failure even cause a loss of 1st and 4th? Link to comment Share on other sites More sharing options...
navion Posted June 28, 2005 Report Share Posted June 28, 2005 barberben, My 94 manual for the 4T60E transaxle says that you can check the resistance for the solenoids as follows: Disconnect the wiring harness at the transaxle, Using a good quality volt/ohm meter check the resistance at the transaxle connector. Cavities A-E ("A" shift solenoid) 20 to 50 ohms resistance Cavities B-E ("B" shift solenoid) 20 to 50 ohms resistance Cavities C-E [NOT 4CMW] (TCC PWM solenoid) 10 to 15 ohms resistance Cavities D-E [NOT 4CMW] (TCC APPLY solenoid) 20 to 50 ohms resistance Cavities C-D [4CMW] (TCC APPLY solenoid) 20 to 50 ohms resistance Cavities F-G (Temp. Sensor (some models)) resistance varies with temperature Cavity Description: Cavity A = Ground (PCM) - "A" Shift Solenoid Cavity B = Ground (PCM) - "B" Shift Solenoid Cavity C [NOT 4CMW] = Ground (PCM) - TCC PWM Solenoid Cavity C [4CMW] BATTERY (FROM BRAKE SWITCH) - TCC APPLY Solenoid Cavity D = Ground (PCM) - TCC APPLY Solenoid Cavity E = BATTERY (IGNITION ON) - ALL SOLENOIDS [4CMW - "A" & "B" ONLY ]Cavity F = 5 VOLTS (IGNITION ON) - TEMPERATURE SENSOR (SOME MODELS) Cavity G = SIGNAL - TEMPERATURE SENSOR (SOME MODELS) Remember, the above is out of a 1994 manual. Your vehicle may or may not be the same. The word "cavity" refers to the individual connection points inside the connector. Additionally, I don't believe that the solenoids in the 4T60-E are as prone to failure as the ones in the 4T80-E transaxles are. The main reason that the solenoids in the 4T80-E transaxels failed was due to the fact that they were used to secure a screen assembly in the channel plate. The new solenoid kit supplies a bracket to perform the function of holding the screen assembly in place. I may be mistaken, but I believe that the shift solenoids in the 4T60-E are under the transaxle side cover, not in the lower pan as in the 4T80-E. So replacing them would be a serious undertaking. Good Luck, Britt Britt Link to comment Share on other sites More sharing options...
barberben Posted June 29, 2005 Author Report Share Posted June 29, 2005 Does anyone have any info on 4t60E solenoids? Link to comment Share on other sites More sharing options...
adallak Posted June 29, 2005 Report Share Posted June 29, 2005 Does anyone have any info on 4t60E solenoids? navion provided you with lots of info... did you go through the procedure to determine the condition of your solenoids?
