Why does my Chevy Tahoe not go into 3rd gear?

Click to expand… Hi, The gearbox contains two shift solenoids, one for the 1st & 2nd, and the other is for the 3rd & 4th. Your problem is a blown shift solenoid. The pan is to be taken out and the solenoid replaced.

Is there a problem shifting from 2nd to 3rd gear?

Have check engine, the computer says it needs the shift solenoid, the problem is it will not shift from 2nd to 3rd gear on an automatic transmission. Also found a vacuum line near to transmission disconnected but not sure where it goes.

What kind of transmission does a Chevy Tahoe use?

The 4L60-E is found in nearly every GM rear-wheel-drive application, including the C/K Truck, Sonoma, Jimmy, Tahoe, Yukon, Astro, Safari, Suburban, Bravada, Firebird, Camaro and Corvette Before the Late 4L60-E transmission, there was the Turbo 700R, which was introduced in 1982.

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.

What happens if there is no 3rd gear on a 4L60E?

Without being able to lock, it won’t be able to facilitate the transfer of energy to the upper gears and the transmission will remain in 2nd gear. Your 4L60E has a set of clutches that work with both 3’rd and 4’th gear. It’s referred to as the 3-4 clutch pack. A bad 3-4 clutch pack can certainly cause the 3’rd and 4’th gear to stop working.

What causes the No 3rd or 4th gear problem?

One of the most common (and most frustrating) problems that happens to the 4L60E is when it loses 3rd and 4th gear at the same time. This leaves you driving around a car or truck that screams down the road. So, what causes the no 3rd gear or 4th gear problem?

What to do when automatic transmission won’t shift into 3rd gear?

Check the Throttle Cables. Changing the fluid solves plenty of transmission issues but if the problem of automatic transmission won’t shift into 3rd gear persists, the parts you should check are the throttle cables. A defective cable with excessive slack is likely to create issues with smooth shifting of the gears.

Why is my 4L60E not shifting into 4th gear?

Below are some common things that fail in the 4L60E and cause this problem. It probably goes without saying, but if you put the vehicle into second gear manually, you’ll still be able to get to where you need to go. If you end up with a bad sprag, the 4L60E won’t be able to shift into 3rd or 4th gear.

Can a bad clutch pack cause 3rd gear to stop working?

It’s referred to as the 3-4 clutch pack. A bad 3-4 clutch pack can certainly cause the 3’rd and 4’th gear to stop working. In fact, once the transmission “shifts” into third, it’ll feel like you lost the whole thing. You can shift into second to get yourself home. Just be careful on the highway.

What causes a car to have no 3rd or 4th gear?

If your transmission happens to be having an electrical problem, it could very well disable the third and fourth gear. If you have a service engine soon light on, it’d be a great place to start looking for your no 3rd or 4th gear problem.

Are there transmission problems in the Chevy Tahoe?

No warning messages in the message area. Currently sitting at a GM service dealer until they reopen on Tuesday. 6-9 months ago we had to have a pressure regulator solenoid replaced in the trans because of extended delayed shifting going from 2->3. Not sure if it’s related to this but these transmissions should last longer than this.

What to do if your transmission won’t shift?

If the level is low, check for a leak in the input and output shaft seal, fluid lines, pan gasket, and the cooler. If there is no leak, flush out the old oil and refill the container. Also, don’t forget to look into the radiator for checking the coolant fluid. Sometimes, the cooler inside the radiator can leak and spoil the radiator coolant.

What causes a car to not shift gears?

A defective cable with excessive slack is likely to create issues with smooth shifting of the gears. It may also totally stall the shifting. A defective PCM could be the reason too. A faulty PCM (powertrain control module) will affect the transmission performance because it controls the gearbox mechanism in most car models.
