Question about 1997 Chevrolet K1500

Open Question

Want to know what color is c1,c2,c3,c4 on my vcm side of wiring harness

I was in the process of converting my 1997 chevy ext cab from the 4l60e to the 4l80e. Had the 4l80e installed and started convertion on wiring. I followed all steps on wiring diagrams tranny side then VCM WIRING SIDE. Now im converting it back to 4l60e and i dont have my print outs of when i did the convertion,so if anyone can help me out on details on converting everything back to its original state would be great.Also, i wasnt ever able to get VCM reprogrammed for the convertion. I'm still not sure which plug for vcm is c1,c2,c3,c4 as they are color coded. Its been about two years since the truck has been converted. Thanks alot , Dustyj.

What transmission will interchange with my truck a 1998 chevy 1500 with a ext cab with a 4l60e

You can replace it with another 4L60E 1998 and newer and you can upgrade it to the 4L65E which is the same but uses 5 planetary gears in stead of 4 that is used in the 4L60E.
1998 was the change off year i believe where they started to section off the transmission in to three parts. The bell housing, body and tail end. The tail shaft housing uses 5 bolts to connect to the transmission and the 1997 transmission and earlier uses 4 bolts, but internal parts had no changes other then the 4L65E.
Thank you for using fixya and good luck.

The following diagnosis might be helpful if the vehicle exhibits the described symptoms.

Check Engine Light with a P0300 due to 2 - 4 cylinders misfiring on the same bank of the engine. DTCs P0171, P0172, P0174 or P0175 may also set for the misfiring bank.

If the published misfire diagnostic does not isolate the cause, perform the following suggestions as necessary:
  • Perform a fuel injector balance test for all 8 cylinders. If a fuel injector concern exists, it is possible to misfuel an entire bank of the engine, causing multiple cylinders on the same bank to misfire even though the root cause is a single fuel injector.
  • Inspect O2 sensor connections on the misfiring bank for corrosion or water intrusion. If water intrusion is found on the right bank, it may be due to the AC Evaporator Condensation dripping onto the O2 sensor harness. If this condition is found, reposition and shield the harness to prevent a repeat concern and repair the connections.
  • Check for excessive exhaust backpressure using the restricted exhaust diagnosis.
  • Swap the Position 1 O2 sensors side to side to see if the misfires move to the other bank of the engine. If so, replace the O2 sensor.
Please follow this diagnosis process thoroughly and complete each step. If the condition exhibited is resolved without completing every step, the remaining steps do not need to be performed.

NOTE: GM bulletins are intended for use by professional technicians, NOT a "do-it-yourselfer". They are written to inform these technicians of conditions that may occur on some vehicles, or to provide information that could assist in the proper service of a vehicle. Properly trained technicians have the equipment, tools, safety instructions, and know-how to do a job properly and safely. If a condition is described, DO NOT assume that the bulletin applies to your vehicle, or that your vehicle will have that condition.
