Hi there. The 4l60e transmission could have two things wrong with it. Either the park arm is not disengaging inside the transmission making the transmission load up but not rotate the drive shaft or the transmission is low on oil. Check the oil on the transmission dip stick and see what the level is. The level must be checked with the engine running. If the oil level is at the full mark, then it is possible that the torque converter may have damaged the pump.

Remove a cooler line and put it into a bucket, and for a brief moment start up the engine and shut it off. If oil sprays out of the cooler line, then the pump is producing pressure. However, if no oil comes out of the cool line, then the pump is not working.

If you need further assistance troubleshooting your transmission, then I recommend having the transmission problem diagnosed by a local expert, such as one from YourMechanic. You will be be able to make a better decision about the car after finding out exactly what’s wrong with it.

Q: I drove my car about 50 miles without the oil cap it started rattling and cut off and now it wont crank

Having driven that far with no oil cap, it is likely that the engine oil level ran low enough to cause engine damage, possible seizing the engine. If that is what happened, adding oil will not help once the engine...

Q: Transmission is slipping into 2nd gear (transmission fail safe).

Hi there. Sounds like the accumulator in the transmission for the shifting from 1st gear to 2nd gear could have a cut on the seal or a broken spring. This will make the transmission slip out of 1st gear and...
