Hello this is my first post on here. So Im thanking all of you for any input on this problem. Here it goes............
Im having transmission problems on my 2001 GP-se. First off its giving me these three error codes (P0753, P0758, P1860), 1-2 and 2-3 shift solenoid and TCC pulse width modulator errors. When you stick it in Drive and take off it starts out in 3rd gear instead of kicking down to 1st. When you pull it down into 1st it will only take off in 2nd gear, or while driving I can pull it form 2nd to 1st and it will not engage 1st gear ever. It will not kickdown while moving in drive if I step on the pedal to get it up a hill, I have to pull it down into 2nd to get it moving. I have checked voltage down to the trans housing on the harness connector. Im getting the proper 12 volts to pin E on the harness, and also checked the resistance of each solenoid on the transaxle case connector. 1-2 gets 23K, 2-3 gets 23K, and TCC is getting 12K, I have also Cleared these error codes after testing and they keep coming back. My routine to get the car moving consists putting shifter in 2nd then shift to third then I can here it shift to 4th but the convertor never feels like it locks up, I have to do this since if I leave it in drive it stays in 3rd. I looked at the ohms resistance chart and see that all three of my error codes are tied into pin E (pink) on the harness. 1-2 is A-E, 2-3 is B-E, TCC is T-E, I have checked there resistance by going through A-E for the 1-2. Im not sure if my 1-2 solenoid is stuck in 2nd or if I have a problem with my range selector. Im lost as of now and will be greatly appreciated of any knowledge I can pull from you guys/gals.
