Is there a manual shift on a 4L60E?
Is there a manual shift on a 4L60E?
Transmission does not shift automatically, only manually. New PCM, check wiring, check other sensors such as VSS and TPS. 23. 3rd gear starts, can manually shift through all gears. When car has been turned off for a bit, then back on it will run normally.: VSS dropoff w/ Hi-stall converter.
What are the problems with the Chevy 4L60E?
23. 3rd gear starts, can manually shift through all gears. When car has been turned off for a bit, then back on it will run normally.: VSS dropoff w/ Hi-stall converter. The rpms are too high, but VSS is showing no movement. Happens after a tire burning take-off.
What to do if your 4L60E transmission breaks?
Check the yellow spring inside the accum housing for breakage. Also, if the accumulator housing walls are scored, the housing must be replaced. TPS needs to be checked for smooth and linear electrical response over the entire range of motion.
What’s the worst case of a transmission leak?
Middle case: leak in the 2nd gear apply circuit (servo assembly or 1-2 accumulator). Double check by using the pressure gauge and watch for a big drop when the PCM commands 2nd gear. Worst case: poor line pressure rise (see below).

How does acceleration affect the gear transmission system?
The issues with acceleration can lead to gear transmission problems as the ECM doesn’t get the correct information about the acceleration. This leads to incorrect shift points which can cause both early or delayed shifts.
What causes soft shifting on a Honda Accord?
Soft shifting, gradual performance degradation: Poor line pressure rise due to leaking boost valve, clogged EPC filter screen, failing EPC solenoid, or worst case: leaky seals throughout. Seal restorer may fix last problem, but probably remove and rebuild needed.
