GMC Savana 2500 Valve Body Parts Questions & Experts Answers
Q: How to replace the control valve body in a 4L60-E/4L65-E/4L70-E automatic transmission on GMC Savana 2500?
A: You must start by taking out the fluid level indicator before lifting the vehicle. You should remove the Oil Pan with its gasket and the filter as next steps. A small screwdriver unlocks and rotates the tcc pwm solenoid. This allows easy unscrewing of its retaining bolt. You can reach the tcc solenoid retaining bolts and components (68 and 66) when you remove the tcc pwm solenoid from its spot. Keep the o-ring seal intact. Separate the harness before removing bolt (64) and spring assembly (63), then disconnect all Valve Body bolts. Slowly lower this part after detaching the control body from the manual valve link. You first put the checkballs (1-7) in the Valve Body before entering the control Valve Body through the transmission case while attaching the manual valve link. Secure the manual valve link correctly before manually tightening the bolt (M6 X 1.0 X 47.5) at the middle of the Valve Body to keep it positioned. Use your fingers to install and lightly tighten 15 bolts including 12 Valve Body bolts (62), 2 bolts (59), and 3 bolts (120) into their specified locations. Secure the transmission connecting cables to the Valve Body before installing the tcc solenoid valve and its bolts (68). Tighten these bolts to 8-14 nm (6-10 lb ft) while avoiding excessive force. Check if all bolts are positioned correctly in the Valve Body. Use a spiral pattern starting from the center to tighten all bolts until they reach 8-14 nm (6-10 lb ft). Insert the tcc pwm solenoid valve (396) alongside its retaining piece (395) into position. Fasten the wiring harness into place and link all electrical components (1-6) together. Finish the job by adding the Oil Pan and filter then lower the car to fill the transmission with dexron(R) vi fluid up to its specified level. A scan tool should be used to reset tap values according to manufacturers' instructions because this process involves the ecm or pcm units that could modify transmission response.
