- This part is for 2011-2013 Buick Regal models; the car was not sold in the US from 2005-2010.
- Symptoms like harsh shifting, slipping, or being stuck in gear are primary indicators of a failing solenoid.

Is This The Right Guide For You?
This guide is for owners of the fifth-generation Buick Regal in the North American market, specifically model years 2011, 2012, and 2013. The Buick Regal was not sold in the United States between 2005 and 2010, so this part and its related issues do not apply to those years.
Common Symptoms of a Failing Transmission Solenoid
A bad transmission control solenoid can make your Regal difficult or unpleasant to drive. The symptoms can appear suddenly and may get worse over time. Common signs include:
- Harsh or Delayed Shifts: You may feel a noticeable jolt or hesitation when the transmission shifts gears, especially during acceleration.
- Stuck in Gear: The transmission may get stuck in a single gear, often second or third, as a protective measure known as "limp mode." This is to prevent further damage and allow you to drive to a repair shop.
- Failure to Shift or Engage: In some cases, the car may rev high without shifting, or there might be a long delay when shifting from Park into Drive or Reverse. Some owners have reported the car feeling like it's in neutral even when in gear.
- Transmission Slipping: The engine RPMs might increase, but the car doesn't accelerate accordingly. 🎬 Watch this video to diagnose transmission shudder and slipping issues. This indicates the transmission isn't properly engaging the gear.
- Check Engine Light: A failing solenoid will often trigger the Check Engine Light. Common trouble codes include P0750, P0755, and P0760.
Check for Other Possible Issues
Some symptoms of solenoid failure can overlap with other transmission problems. For 2012-2013 Regals, a Technical Service Bulletin (TSB #12222B) noted that an incorrect internal o-ring could cause sluggish shifting and poor acceleration, mimicking solenoid issues. Always consider a full diagnosis before replacing parts.

When replacing the transmission control solenoid, you have a choice between Original Equipment (OEM) and aftermarket parts. For a critical component like this, brand quality matters.
- OEM (ACDelco): ACDelco is the original parts supplier for General Motors. Choosing an ACDelco solenoid guarantees a perfect fit and original performance. This is the safest, but usually most expensive, option.
- Premium Aftermarket (Standard Ignition): Brands like Standard Ignition (Standard Motor Products) specialize in producing parts that meet or exceed OE specifications. They are a reliable and cost-effective alternative to the dealer part, often with their own robust warranty and quality control. For this repair, a brand like Standard Ignition is a dependable choice.
- Store Brands (Duralast, etc.): Retailer-specific brands can be a budget-friendly option. While some perform well, quality can be less consistent than premium brands. Given the labor involved in this repair, saving a few dollars on the part itself may not be worth the risk of premature failure.
Pro Tip: Consider a Solenoid Kit
Your Regal's transmission has multiple solenoids. If one has failed due to age and mileage, others may not be far behind. Often, solenoids are sold in a pack or kit. While the initial cost is higher, replacing them all at once can save you from having to do the same job again in the near future.
Estimated Replacement Costs
The cost to replace a transmission control solenoid can vary based on your location and whether you do the work yourself. The part itself is relatively affordable, but accessing it requires labor.
| Part/Service | Estimated Cost |
|---|---|
| New Aftermarket Solenoid (Standard Ignition) | $80 - $90 |
| New OEM Solenoid (ACDelco) | $110 - $150 |
| Shop Labor (2-3 hours) | $250 - $450 |
| Total Professional Replacement | $330 - $600 |
Frequently Asked Questions (FAQ)
