\"2009
\nI have Code P0752 on my Chevrolet Traverse 2009 with transmission problems , fault codes P0752 , P0989 , P0877,
\nI want to replace the valve body with TCM & speed sensors.
\nMy question: is reprogramming required after installation?
\n————————————————————
\nRESPONSE<\/strong><\/p>\n

Yes, the new TCM requires reprogramming.<\/p>\n

Code P0752 – 1-2 Shift Solenoid Valve Performance – No Second or Third Gear<\/h2>\n

Code P0752 Possible causes<\/h3>\n

– Low transmission fluid level
\n– Dirty transmission fluid
\n– Faulty 1-2 Shift Solenoid valve
\n– 1-2 Shift Solenoid valve harness or connectors
\n– 1-2 Shift Solenoid valve circuit is open or shorted<\/p>\n

Code P0752 Description<\/h3>\n

The 1-2 shift solenoid (SS) valve controls the fluid flow acting on the 1-2 and 3-4 shift valves. The 1-2 SS valve is a normally-open exhaust valve that is used with the 2-3 SS valve, in order to allow four different shifting combinations.<\/p>\n

Code P0752 is detected when<\/h3>\n

The P0752 code is detected when the gear required by the ECM does not match the actual gear when vehicle is driven.<\/p>\n

Code P0752 Related symptoms<\/h3>\n

– Engine Light ON (or Service Engine Soon Warning Light)
\n– Transmission will not shift gears.<\/p>\n

P0989 – Transmission Fluid Pressure Sensor\/Switch E Circuit Low
\nP0877 – Transmission Fluid Pressure Sensor\/Switch D circuit Low<\/p>\n
