Transmission is slipping, shuddering at low speeds making car unsafe to drive

Transmission startes slipping then went out

Filed Jan 27, 2024 · Transmission · PA

I noticed shuddering while driving my car and when I took it to my mechanic upon test driving and inspecting it he realized the torque converter is not strong enough for the size of the car. He informed me driving it with the improper size will cause it to shudder and accelerate or not accelerate correctly while driving and cause slipping while shifting gears. Those issue have been happening the entire time I've had it and if the car slips and goes too fast or slips and loses power it is a danger to me and the other cars on the road. There were no codes or warning indicators while this is happening.

When it is parked and idling it sounds like it wants to stall. When I am driving it it shifts hard and the transmission starts slipping. I took it to a reputable mechanic for an assessment of the problem and he said his computer said that it was the traction control module in the transmission and that it would cost about $1500 to repair it including labor. He called the dealer to see if it was in stock and they said they had many of them. I would assume that they would not stock a $700 part in that quantity if they were not having quite a few problems with this part. Other SUV's have been recalled and I was wondering why mine was not. I would appreciate it if you could look into this matter for me and get back to me with an explanation. Thank you for your time as I may be getting stuck somewhere with my wife and children in the car..

The transmission is slipping or shuddering under certain conditions. Most frequently noticeable around the shift points between 2nd&3rd, or 3rd & 4th, especially when the engine is downshifting to climb a hill. There is a strong vibration and RPM bounce a bit before it finally engages after a couple seconds. I have recently learned that acadias have a long history of transmission problems, notably the torque converter and wave plate.

While driving at highway speeds last week my 2012 awd acadia having a major malfunction. 1. While driving, door locks engage/disengage 2. Trans appears to slip into neutral (high rev/ no power) 3. On the dashboard digital readout the transmission "blinked" into p from d (while driving) 4. Traction control engages/disengages and the vehicle lurches forward and hard stops 5. Trans enters some sort of limp home mode where it allows me to drive only up to 60mph, @4000 RPM (like 3rd gear) this process repeated continually for over an hour drive to the dealer, normal operation appeared to occur at speeds below 45mph, but only temporarily and the issue continued again at the lower speeds. I call onstar and they pull codes for me while enroute to the dealer: ECM code =u0101 TCM code= none (failed to probe module) ABS code= u0101 ABS code= c0561 (issue with traction control system)- "service within 7 days" a quick search in automotive forums reveals several other people with almost the exact same issue, with no specific solutions.

Tl* the contact owns a 2012 gmc acadia. The contact stated that the transmission had been slipping in any gear from shifting out of park. The contact had to apply the emergency brake to prevent a potential failure if it may progress with no warning while changing gears. The vehicle has been inspected by an independent mechanic who suggested that the vehicle be taken to a dealer for inspection, diagnosis and to determine if there was a recall to service the transmission. A dealership has not been contacted yet. The manufacturer was contacted, had issued 38 tsb on power train and no recalls for power train/transmission yet. The vehicle was not repaired yet. The VIN was not available. The approximate failure mileage was 115,116.
