Can a car shift in and out of gear when not running?

The transmission will shift in and out of gear without any issue when the car is not running. It won’t come out of the reverse gear when the car is running. You can push the clutch to the limit but the engine almost halts upon allowing the clutch out.

What happens if there is no lubricant in the gearbox?

Can a 4L60E have a bad 3-4 clutch pack?

Your 4L60E has a set of clutches that work with both 3’rd and 4’th gear. It’s referred to as the 3-4 clutch pack. A bad 3-4 clutch pack can certainly cause the 3’rd and 4’th gear to stop working. In fact, once the transmission “shifts” into third, it’ll feel like you lost the whole thing. You can shift into second to get yourself home.

What happens when the TCC fails to disengage?

If the TCC fails to disengage when the vehicle comes to a stop, the engine will stall . Before attempting to diagnose converter clutch electrical problems, mechanical checks such as linkage adjustments and oil level should be performed and corrected as needed.

When does the torque converter slip during lockup?

About 10K miles ago, I started noticing that at lower speeds when the torque converter should be fully locked (50-60MPH), that it will lockup like expected, but then there will be a couple seconds of slippage, allowing the engine RPM to increase 200-400 RPM, and then back to full lock.

What to do when PWM valve slips on 4L60E?

A quick fix for this is to lock the PWM valve into full pressure position (via inserting a spring in the bore), and getting on/off TCC engagement as in the pre-electronic 4L60E (the 700R4s used an on/off strategy until 93 when they became the 4L60E).
