Transmission issue

Welcome to 2CarPros.

The first thing I suggest is to check the transmission fluid. Confirm it is clean and full. There is a dipstick used to check it under the hood. When checking, make sure the engine is at operating temp, running, in a level surface, and in park. Let me know what you find and the fluid color.

Also, let me know if the check engine light is staying on when the engine is running.

Take care,

Joe

Welcome back:

That looks and sounds normal. Now, it could be several other things. It could be related to a partially plugged transmission filter reducing line pressure, a pump issue, a shift solenoid issue, or even a problem with the transmission control module (TCM). Since the check engine light isn't on, most likely there are no diagnostic trouble codes stored. At this point, it becomes a guessing game. When I say guessing, I mean which thing do we check first. The easiest would be to drain the fluid and check for contaminates in it such as clutch material or metal shavings. Next, transmission line pressure would need checked to make sure it is within spec. And the list goes on.

If you want to walk through it, let me know. Honestly, without a trouble code, it makes things much more difficult.

Let me know.
