Moreover, a faulty fuel pressure regulator may easily overwork or underdeliver fuel by the fuel pump, leading to erratic engine behavior. This inconsistency can cause hard shifts, particularly during acceleration. Replacing a malfunctioning fuel pressure regulator will generally range in price between $150 and $300, though proper fuel pressure helps in preventing transmission problems.
A recall by Ford in 2018 of over 50,000 vehicles for problems with fuel pumps highlighted the interrelation between rough gear shifts and engine performance. With weak or failing fuel pumps, the vehicles in question stalled and had rough transitions between gears because of low fuel pressure. This is a good example of how a compromised fuel system could affect other components, such as the transmission, and make it malfunction.
Not only is rough shifting uncomfortable, but longer-term effects of this can be damage to the transmission. Repeated rough shifts because of problems in the engine could result in wear and tear of the components of the transmission at an increased pace. This would increase the likelihood of costly repairs. According to estimates by AAA, the cost of repairing a transmission could range from $1,000 to $4,000, depending upon how serious the damage is.
However, while its impact may predominantly center on the engine, a bad fuel pump easily and rapidly works its way to poor shifting. In conclusion, though a bad fuel pump's impact is primarily experienced in the engine, these issues do have a way of cascading to rough gear shifts with great ease. Thus, regular maintenance of the fuel system will prevent rough shifting and keep both the engine and transmission running longer. For more on how to keep your fuel system healthy, go to Fuel Pump.
Can a Bad Fuel Pump Cause Rough Gear Shifts?
Sure, it can-rough gear shifts in a vehicle can be because of a bad fuel pump. This fuel pump always operates to deliver a continuous amount of pressure and flow of fuel to the engine. If the proper amount of it could not be delivered appropriately, the performance from the engine may falter or experience some sort of impact on the transmission. Most fuel pumps usually push the fuel at either 40 psi or 60 psi, depending on the needs of the vehicle. In instances where there is a failing pump, if the pressure drops, the engine may not be able to generate enough power. This could result in rough or late shifting.
Transmission systems rely on predictable engine performance in order to time shifts properly. A weak fuel pump, for one, can result in hesitation or misfiring in the engine-when trying to pull under load or when accelerating. If the required power from the engine is not delivered, the transmission may be unable to shift very well. According to Consumer Reports, a rough-shifting problem is related to poor performance of the engine about 5-7% of the time, owed to the fuel system.
Another cause for rough shifting is a clogged fuel filter. While in operation, the fuel filter may block due to accumulated debris over time and reduce the flow rate of fuel. The restricted flow will apply more stress on the fuel pump to be able to produce its rated capacity, and this may eventually result in fluctuating fuel pressure. Bosch recommends the replacement of the fuel filter every 20,000 to 40,000 miles to avoid any fuel delivery issues that may eventually result in rough shifting. Neglecting the fuel filter can lead to the fuel pump becoming incapable of performing up to 30% of its full capacity, hence directly impacting the performance of both the engine and the transmission.
