2024 tranny questions

[fh4ever]

I have just over 30k miles on my recently purchased of an used 2024 edge 2.0.  I have noticed a couple things regarding the transmission.   I have noticed if I pull out onto a street that is steep and allow it to coast downhill to get up to speed (without pressing the gas pedal), it seems the torque converter is already locked up.  As the car goes downhill faster, the engine rpm increases to a point the tranny shifts into the next gear.  The rpm falls back with the gear change, and as the car picks up more speed again, the rpm goes up to a point and again shifts to the next gear.   This repeats a few times until 25 or 30 mph is reached.  At that speed, its hard to tell if the engine is still holding the car back.  

My question is, did Ford design the transmission to operate this way?  All other automatics I have ever owned have freewheeled going downhill and will go faster and faster without the engine or transmission ever holding the car back.   I asked the "very young" service tech at the dealership about this and he said with his 2 years on the job, no one has ever complained about it.

My second question... I have noticed in heavy stop and go traffic, there is some tranny shudder around 20-25 mph while barely giving it throttle.  Almost as if it it hunting the gear it needs to be in...or as if the torque converter is already locked up not allowing smooth shift.  It seems this is more noticeable on the hot summer days in heavy stop and go traffic from stop light to stop light.  If you give it more gas and go on and accelearate, I do not notice it.  I have also noticed at less than 20 mph speeds, when you let off the gas pedal, the engine is slowing the car down...again as if the torque converter is already locked up. I would expect you could coast to a stop with the engine slowing you down.  Anyone elses Edge do the same thing? 

Todays trannys are so complex, temperamental, and costly that if there is an issue, I want to address it before the warranty expires.

First and most obvious question:

 

Was the transmission fluid ever changed?  Most likely not and you probably have no idea how that car was treated before you bought it.

 

Step 1:  Change the transmission fluid

 

Whenever one buys a used car, one has to expect to perform routine maintenance, at least, on the car just purchased.

Transmission fluid change at 30~40K miles might be prudent for a vehicle that's frequently used for towing, otherwise around 50~60K miles for typical use - being a used vehicle with unknown history is may be good insurance to change it early.

 

@fh4ever I have owned other vehicles that exhibited similar transmission behaviour you describe and it was considered normal.

 

If still in doubt take a test drive in a similar vehicle at your local Ford Dealership, and if still in doubt after that have it checked by a transmission specialist shop.

 

Do you still have warranty on your vehicle? - if so submit a warranty request.
