Shift but won't go into gear just revs

From the sound of your problem, I suspect that your problem lies with the clutches and bands. When your transmission is operating normally, you make your gear selection and the torque converter responds by ramping up its revs so that the transmission spins up and the proper gears are set. In response, the clutches and bands come into play so that the engine and the transmission link and your car then moves forward in the proper gear. The problem is that the clutches are not engaging properly (or at all) because the bands, which tighten in conjunction with the clutch action, are likely slipping. The result is that your engine revs, but your pickup doesn’t go anywhere.

There is another possibility, though, which is that one or more of the solenoids on or in the valve body have failed. When you lose a solenoid, however, you only lose one or two gears and the transmission should go into limp-home mode so that you can get your vehicle to the service area. It is highly unlikely that both of the solenoids that act for your pickup’s forward gears have failed. It is a possibility that should be checked out.

There is one other possibility that I am throwing out so that you will know it. It is that the valve body has failed and is not directing the transmission fluid to the correct sections of the transmission and your vehicle is standing still, as it is doing. And, believe it or not, it isn’t because the entire valve body has failed, either. You see, the valve body contains a series of galleries through which the transmission fluid is directed. That direction is handled by a series of check valves — little more than a ball-bearing seated on a spring — that open and close in response to the flow of the transmission fluid. So, if it isn’t flowing down the gallery or galleries needed for your truck to move ahead, then you have a valve body problem.

As you can see, there are many different ways for this problem to play out. Why, it might even involve the torque converter and the input shaft, though, it is really unlikely in your pickup.

So, you are looking at putting a rebuilt transmission in place which will cost you between $3,000 and $3,200, depending on your location (at some particular brands and in some locations the bill could actually hit $4,100, while at other spots it might be as low as $2,850). I hope I’ve helped. If you have anymore questions please let me know here. I’m always glad to help.
