4l60 valve body diagram

Pressure too low, pump worn or internal leakage. Also sticking valve body valves or checkballs.

Went from 2nd to 4th? 3rd clutches are gone. Wouldn't shift to 3rd or OD. Solenoid or valve body problem. Have the codes read. Not sure for the year... 4l60 or 4l60e?

YEP 4T60E HAS A THROTTLE DOWN SHIFT CABLE.YOU NEED THROTTLE CABLE TO CONTROL THROTTLE VALVE AND ALL SHIFT VALVES IN VALVE BODY.YOUR THROTTLE VALVE CABLE CONTROL TRANSMISSION LINE PRESSURE THROUGH THE VALVE BODY.WHICH CONTROLS ALL SHIFTS.

It s inside the transmission and there several of them along with other valve body solenoids for tempature and fluid pressure . Icould sent you pictures out of the manual of the locations .But all of these valve body shift related valves are related and one valve can send a code for an other and with out the proper test equiptment to correctly diagnosis the problem its complacated and not likely the real couse of the problem . If you give me an Email address you should have the 4L60-E transmission in that truck . But honstly I would take it to a transmission shop its just to speicalized and two many things can be wrong. If you want it i will send it good luck with it

what kind of transmisson is this 4t40or 4t60 or 4t65 or 4L60 ..well most general motor solenoids are located on the the transmisson valve body . which means on a rear wheel drive the transmisson pan needs to be remove to gain access to the valve body . On a front wheel drive the valve body is located under the side cover on the transmisson . Now if i remember rigth there are 3 or 4 control solnoids . 1-2 shift 2-3 shift and a Tcc solnoid . you need to know which one to replace and what location are they on the valve body

there is a recall with these transmissions, th correction involves removing the valve body from the tranny and drilling larger holes, its not something easily done as u have to be extra clean and precise. google 4l60 problem, and you will find many articles about it

The key distinction of the Later 4L60-E (1997-2006) from the Early 4L60-E (1992-1997) or 4L60 (1990-1992) or 700R4 (1982-1989) is the six-bolt "hex" rear output or tail housing / adapter pattern. The previous versions featured a four-bolt square bolt pattern at the adapter or tail housing. This is where that made the small change and the 96/97 year was a change over year so you may have the newer housing or the older housing, but if your replacing the transfer case with the transmission your good to go, the electronics are the same. Just the body housing is different. Good luck and hope this helps. And why wold you want to convert the transmission, there are lots of easy simple up grades with out dropping the transmission or valve body. 

The shift solenoid is in the valve body in the transmission, i recommend that if you have not worked on a 4L60 transmission before. Have a transmission tech do it for you, if money is the issue. You can drop the transmission oil pan and then drop the valve body and bring  it to a transmission shop and have them clean and replace the shift solenoid in the valve body just to make sure you replaced the right solenoid. There are more then one. Good luck and hope this helps. 

It sounds like you may need a rebuild but it could be you have a valve stuck in the valve body.
good luck

THE VALVE BODY IS LOCATED INSDIE THE TRANSMISSION PAN UNDER THE TRANS FILTER
