Why is my 4L60E not shifting into overdrive?
As the 4L60E ages, one of the most common problems that it develops is that it won’t shift into overdrive anymore. Without overdrive, your vehicle turns into a time machine and takes you back to an era where it was the norm for a vehicle to scream down the highway at 3000 RPM.
What happens when there is no overdrive in the transmission?
When the temperature sensor reports 30 degrees F or colder, there will be no overdrive, and below 50 degrees F, there will be no torque converter clutch. If the transmission fluid temperature sensor reports an overheating condition (over 260 degrees F) and the transmission is currently in overdrive, the TCM will downshift to third gear.
Why is my overdrive gear no longer engaged?
Band Failure – Most of the time the overdrive gear is going to fail to engage due to the wearing of the band for the Overdrive. The servo will no longer be able to engage it because of this wear. This is the physical problems that stops overdrive most of the time if no other issue is detected.

When does the transmission go into overdrive?
Oh, 45 mph for example. The transmission shifts into overdrive and engine rpm drops below 1400 rpm. At this low engine speed, the transmission downshifts to 3rd gear, as designed, but then rpm goes up again and it meets one of the conditions to go into overdrive.

Why does my Dodge truck not shift into overdrive?
Truck makes absolutely no effort to shift into over drive. Shifting is NOT erratic. Cruise control and speedometer STILL work. Is this a bad overdrive solenoid, tps sensor or something else!?!! :doh: :confused013: I also get “CODE 36”. Try pulling codes with an OBDII scan tool.
