Question about 1997 GMC Sierra K2500

1 Answer

Sometimes I start my 1997 GMC Sierra k1500 4x4 and the little light that moves under the P R N D 3 2 1 as one shifts the automatic transmission, does not come on. When it does not come on, neither the speedometer or odometer work and the truck drives with considerably less power. It drives as if it's stuck in one gear: it takes a lot of gas to get going from a stand-still, and as it gets to 60 miles an hour (as a guess. I don't know exactly how fast it's going because the speedometer is still pointed at zero) it doesn't shift gears. Further more if, at 60 miles an hour, the truck begins ascending a hill it won't down shift to maintain the speed. What's even weirder is that I came upon this problem about a year ago when it frustrated me for maybe two months; then it went away for six months and my truck ran great. Now it's back. Another thing: I really only have to deal with this when the truck engine gets up to normal operating temp. This never happens when the engine is cold.

More likely the shift cable is binding. Also make sure you fully apply the emergency brake when you park before shifting into Park. This will prevent loading the linkage by the parking pawl making it difficult to move the lever. Especially when parking on a hill.

Also make sure you are pressing the brake pedal when shifting our of Park. Sometimes the brake light switch can be intermittent and either the switch is bad or the switch is out of alignment with the brake pedal lever. This not the most common cause.

The gear shift lever indicators tell you what gear you have an automatic transmission in on your vehicle. The shift solenoid tells the transmission when to shift gears and what gear to shift into. Newer model automatic transmissions have electronic shift solenoids that are activated and change gears based on the speed the vehicle is traveling. Troubleshooting either one of these transmission components is relatively easy if you know a little about automobile mechanics. With the right tools, you can determine whether the transmission shift solenoid is having a problem. Gear shift indicator problems can be determined simply by moving the gears into their designated position.
Transmission Shift Solenoid
  • 1 Raise each corner of the vehicle up with the car jack and place jack stands under the frame. Make sure the car is raised high enough so you can work under the car freely.
  • 2 Slide the drain pan under the transmission fluid drain plug. Remove the drain plug with a ratchet and socket, and let all the fluid drain out of the transmission. Remove the transmission pan bolts with a ratchet and socket. Pull the pan away from the bottom of the transmission, revealing the transmission shift solenoid.
  • 3 Wipe off the shift solenoid with a shop towel. Disconnect one of the two plugs that attaches to the shift solenoid. Turn the knob on the volt meter to the ohms setting, so resistance can be measured. Set the volt meter on 200.
  • 4 Take the black lead of the volt meter and touch the negative battery terminal wire. Take the red lead of volt meter and slide the tip into the terminal plug you just disconnected from the shift solenoid. Look at the reading you get on the digital display of your volt meter. Determine if the reading is between 12 and 25. Readings below 12 or above 25 tell you that the shift solenoid is not working. Reattach the plug to the shift solenoid and pull the second plug attached to the solenoid. Perform the same procedures on this plug wire. Replace the transmission shift solenoid after determining it is bad.
Gear Shift Indicator
  • 1 Move the gear shift into the desired gear. Look at the gear labels and the arrow, or other indicator, to see if the gear shift indicator lines up with the selected gear.
  • 2 Move the gear lever to another gear and look to see if the indicator lines up with the selected gear. Misalignment of the arrow will tell you if there is a problem. Moving the gear shift to "neutral" but having the indicator show the transmission is in "drive" tells you the gear shift indicator is not working properly.
  • 3 Try each gear position to determine how much misalignment is in the indicator. Slide under the car and check for a loose gear shift cable. Check all the gear shift cable connections to ensure they are all tight and are not missing. Tighten any loose gear shift cable clamps or bolts. Replace the gear shift cable if you find that this is causing the misalignment with the gear shift indicator.

How do i check the transmission fluid in a 1997 gmc sierra


Transmission Fluid Fluid Level Checking
  1. Operate vehicle for 15 minutes or until the transmission fluid reaches a temperature of 180-200°F (82-93°C).
  2. Ensure vehicle is on a level surface.
  3. With brakes applied, move the shift lever through each gear range for about 3 seconds.
  4. Place transmission in PARK position.
  5. Set parking brake and allow engine to idle for 3 minutes.
  6. Remove the transmission fluid level indicator and wipe clean. Reinsert the indicator and give it a full twist until fully seated.
  7. Remove the indicator.
  8. Observe sides of the indicator. The lowest level reading must be within the hot cross-hatched area.

1st thing to do is test the system for codes, the problem is most likely a failed or stuck shift solenoid indside the trans, have you ever serviced the trans, sometimes a fluid and filter cahnge will cure these kinds of issues.
