What is the shifting solenoid on a Chevy S10?
The shifting solenoid on a Chevrolet S-10 pick-up is designed to regulate when the transmission shifts. This solenoid is part of the electronic transmission control system, and is controlled by the powertrain control module, or PCM. The PCM actuates the shifting solenoid when it determines that an upshift or downshift is required.
Why does the RPMs get high when changing gears?
The main problem is that the rpms get high when I shift gears. I’ve taken the car to 3 mechanics and they can’t find the solution. There’s no air leaks. Throttle body, throttle position sensor and mass air flow sensor replaced. I’ve had mechanic do a tune up, oil change and I got new battery.
Is it normal for car RPMs to go up at startup?
Based on your follow-up comments, this all sounds like normal RPM ranges. 2,000 RPMs right at startup is normal, just as long as it goes back down after a few seconds or so. (it may stay higher for longer when it’s really cold out).
What does DTC stand for on Chevy S10?
Power on the scan tool and select “PCM” from the main menu. Select “Transmission” from the PCM sub menu. Select “Clear all current and stored DTCs.” DTC is an acronym for “Diagnostic Trouble Code.” Disconnect the can tool from the vehicle and start the engine.

Why does my transmission rpm keep climbing up?
It seems that the gears are slipping and causing the rpm’s to climb up. Check the transmission fluid and make sure that it’s full and red in color. Very dark red or black transmission fluid is an indication that the transmission is burning the fluid for getting too hot from either overloading or slipping gears.
When do I put my truck in drive, the RPMs go up?
When I put my truck in drive and step on the gas the RPM’s go up to 3,000 but my MPH will stay at 10-15 When I let go of the gas a little bit I can feel the truck kind of pull and the RPM’s will g… Stack Exchange Network

When to engage the 4 wheel drive system?
Some older and more basic 4WD systems must by engaged manually with the vehicle at a complete stop and the transmission in either Park or Neutral. Don’t try to engage these 4 wheel drive systems when the vehicle is moving or you can damage expensive components.
What causes a 4 wheel drive car to turn slower?
When driving on a surface with good traction like tarmac or concrete in 4WD mode, this can cause difficulty when turning corners as the inside wheel needs to turn slower than the outside wheel. This situation is called “axle binding” ,”drive-line binding” or “drive-line wind up”.
What causes a 4WD car to under steer?
This phenomenon is caused by the front wheels battling the rotational force coming from the front drive shaft as it tries to slow down the front wheels, causing the massive under-steer effect. You should avoid engaging 4WD on a high traction surface at all costs.
Can a push button 4×4 engage on a 2002 S10?
I have a 2002 4.3 s-10 with push button 4×4. When i select 4 high or 4 low the transfer case will engage and turn the front driveshaft but the front axle will not engage. I jacked up all four tires and tried this.

When to switch from 2 wheel drive to 4 wheel drive?
Most modern 4 Wheel drives allows you to safely switch between 2WD and 4WD provided your speed is below 62 MPH and driving on a slippery surface like snow, sand or muddy tracks. However, those are the only suitable conditions you should engage 4WD mode.
Why does my S10 transfer case not engage?
When it’s open, vacuum will be supplied to the actuator and the cable will be pulled. The cables sometimes do get frozen up – 3/8 inch of movement seems like not enough. If there’s vacuum always on the 4×4 actuator, there’s something wrong with your transfer case vacuum switch.
Why is my Trans bad on my 4L60E?
Trans seems noisy when moving in 1st and Reverse, noise goes away instantly if you shift to N or the transmission goes into 3rd gear: Reaction planetary is worn out due to high miles or insufficient lubrication. Not a critical failure, but not a good sign either.
What causes a WoT Shudder on a 4L60E?
3. 1-2 Shift shudder at WOT (Wide Open Throttle); delayed or abnormal 1-2 shift; There’s a problem ONLY on the 1-2 shift: 1-2 accumulator piston cracked or stuck cocked in the bore. Check the yellow spring inside the accum housing for breakage.
What to do when 2.1-2 shift does not happen?
2. 1-2 shift does not happen at WOT (Wide Open Throttle) until you let off the gas: Best case: try replacing the TPS. Middle case: leak in the 2nd gear apply circuit (servo assembly or 1-2 accumulator). Double check by using the pressure gauge and watch for a big drop when the PCM commands 2nd gear.
Can a GMC Sierra shift into any gear?
Answer: There is no solenoid that will prevent the transmission from going into any forward gear. Shift solenoids control shift 1-2, 2-3, 3-4 and downshifts. You need to get a scan done on the computer to see what code (s) is set.
What did I do with my 1988 Toyota S10?
The vehicle is old and worn, but didn’t burn oil. Before it died there was an issue with chugging, it would shake and buck and rattle the whole drivetrain real bad. I replaced the fuel filter and put some Sea Foam in the fuel and it settled down some but didn’t stop chugging completely.
What kind of fuel spray does a 1988 S10 use?
1988 S10 2.5 TBI, 5 speed. No fuel spray from injector. Got this for my step son who is 1st year electrician apprentice. The vehicle is old and worn, but didn’t burn oil. Before it died there was an issue with chugging, it would shake and buck and rattle the whole drivetrain real bad.
How many volts does a 1988 S10 have?
The red has 12 volts, the blue is supposed to pulse on cranking. It does not pulse. I hooked up a voltmeter and it shows .5 volts for an instant when you start to crank, then 0 while cranking. I have tried a dozen remedies from discussion forums.
Why is my transmission solenoid not working properly?
If the transmission control unit is not able to open, the shift solenoid with help the power or ground, and it will store a trouble code in the transmission control unit on the affected shift solenoid. It’s also possible that the shift solenoid has an internal problem or is stuck so the transmission control unit can’t open it properly.
How much does it cost to replace a shift solenoid?
In the picture above, you see the shift solenoids located on the valve body. The shift solenoids are the tubes with yellow, green, and black colors. A single shift solenoid’s replacement cost is between 100$ to 350$ and a shift solenoid pack costs between 400$ to 700$, including transmission fluid, filter, parts, and labor work.
How do you reset the solenoid on a truck?
When the codes are cleared from the PCM the solenoid is automatically reset. Shift the truck’s transmission into first gear (manual) or park (automatic). Turn off the engine and set the parking brake. Turn the ignition back to the “ON” position but don’t re-start it.
