Delayed Shifting When Accelerating: How To Cure and Maintenance Tips

We’ve all been there at least once before, the moment of paused heartbeats that your car happens to be delayed shifting when accelerating.

So, is this common issue a really bad sign for some repair-needing components? Or are there any cures that can help the situation?

Read on for no more vexing nuisance not yet resolved!

What Is Delayed Engagement In Automatic Transmissions?

Delayed Shifting When Accelerating

The first thing you should know about your engine’s transmission is that it is not supposed to cause the vehicle to operate lingering every time you start traveling.

Yes, intricate mechanisms are undoubtedly the right term to refer to automatic transmissions.

They comprise several car parts, and all of them have to keep their nose to the grindstone so the drivers can achieve their expectations regarding on-going journeys.

That’s why it’s hard to ensure your transmission will not undergo any single deadlock throughout its lifetime.

Nevertheless, saying so doesn’t mean such problems are nothing to worry about. Delayed engagement when accelerating is one of those notably alarming.

This stagnation implies the delay in the period of time, usually responding to whenever your car gear shifts from park mode to a moving gear, like Reverse gear or Drive gear.

The time taken can neither be fast nor extensive, depending on your engine’s inner issues. The acceptable longest one often lasts up to 60 seconds.

If, by any chance, you have to wait for more than that, then perhaps the vehicle is all ready for a trip to the nearest service center.

Sounds like we are making a big deal out of it, but once the worst has come, you’ll figure out the truth eventually.

Why Your Transmission Delays When Shifting Into Drive

The most common culprits are frequently excess mileage and inadequate maintenance.

Yet, the incident in which your transmission suddenly delays when shifting into drive can take place anytime and anywhere because of other numerous reasons.

Among those, one of the leading factors you should highly take care of is transmission fluid.

Functioning as a coolant, this special liquid aims to lubricate interior seals so the engine can steer clear of weariness or hardening.

Once you leave the fluid out of sight for a decent amount of time, there may be a high possibility that your transmission will run out of fluidity.

As might be expected, the result left afterward is no other than integral components that are defenseless and deteriorate in the time to come.

How To Fix Delayed Shifting When Accelerating

To treat the trouble that transmission won’t shift when accelerating, below are the recommended directions.

1. Seals And Bands

Worn-out seals and bands are another explanation that makes sense for delayed shifting high RPMS when accelerating.

Automatic transmission is the contribution of various sorts of mechanisms. Solenoids, bands, gears, and clutches are all those that make appearances.

Here is the sad news: Merely one of these components failing to work well can already cause low internal pressure, leading to delayed engagement and CVT transmission jerks when accelerating.

Unless you’ve got decent engine-related knowledge, there’s no way to get it fixed on your own.

The simple resolution is just to head straight to the nearest garage and let the experts do the job by replacing the needed parts.

2. Shift Solenoids

Shift solenoids

Shift solenoids are the valve body that manages fluid flow through the transmission.

Due to frequent vibrations and heat exposure, the electromagnetic coils or little plungers on the transmission solenoid eventually break, causing the delay in the shifting of gears.

So make sure you check up on that on a regular basis so the changing cure can be on the way in time.

3. Transmission Filter

Transmission Filter

A clogged transmission filter is one more consideration that raises the alarm.

Such a problem can bring hydraulic pressure in the gearbox into becoming lower and lower, resulting in delayed shifting high RPMS when accelerating Ford Escapte as the clearest example.

To iron out such a pickle, the first thing is to take your car to a technician.

That way, they will detach the transmission pan so that the filter can be accessed and get geared up for a whole brand new replacement.

4. Transmission Pump

Transmission Pump

The transmission pump is also what to make a point of. Once the pump fails to progress, it is incapable for the device to deliver the necessary hydraulic pressure.

In such a case, the hydraulic system as a whole will derive shift delays as well as internal damage.

Do’s And Don’ts For Transmission Slips When Accelerating From Stop


  • Get your transmission fluid renewed per 60,000 miles to guarantee that you always have fresh, dust-free fluid in your transmission.

Since such a substance not only lubricates working parts but also serves as a chiller to keep other components from overheating, you’ll know it’s worth the shots once the mission is completed.

  • Frequently checking fluid levels is another must on your checklist.

Little did you know, internal seals might deteriorate or harden due to the lacking or aged, used transmission fluid.

That explains why it’s vital to ascertain that your car is receiving the proper kind as specified by the manufacturer.

Otherwise, it may lead to numerous shifting issues or even catastrophic transmission failure.

  • Make sure that the transmission fluid pump is functioning correctly.

Some simple steps to check your transmission fluid pump are what you can get done at home all by yourself without even the help of experts.

You’ll be good to go if the pump does not fail to produce adequate fluid pressure, which leads to a pretty weighty chain reaction.

As such, the hydraulic system will go astray and result in probable internal damage, delayed engagement, or transmission jerking when accelerating.

  • Get your transmission filter examined by an expert and competent transmission technician.

Swift to a new one once it shows any warning signs of becoming clogged. And that’s how you can avoid permanent transmission damage.


  • Make an effort to resolve a delayed engagement on your own.

You’ve achieved a whole new level of home-tech mechanisms after evaluating that your fluid levels are proper and the color is appropriate.

But this should be where you take a halt; otherwise, a further attempt may likely mess things up and sabotage the engine forever.

The simple solution is just to bring your car to a transmission professional in case you still seek further examination or repairs.

Time-saving and perhaps cost-effective are both coming on the way at the same time!

  • Rev up the engine.

Don’t you have any nostalgia looking back at a scene that happens every single time your vehicle gets delayed or the automatic transmission slips when accelerating from stop

It is understandable that this action is merely a part of our instinct to get the car moving when such things stumble upon.

However, this might trigger substantial injury since increased engine speed causes friction, which can further damage bands and clutches.

How Does Automatic Transmission Know When To Shift Gears?

This procedure is actually pretty straightforward to catch on. It is all thanks to software updates featured in the transmission that incorporates data from several sources.

Due to the program, not only can it tell how fast the automobile and the engine are moving, but it also knows how much strength you slam on the brakes.

And believe it or not, such an attitude giving toward your accelerator pedal reveals quite decent your desires for the trips coming. The more you hit the gas pedal, the faster you want the speed to turn out.

Since the transmission is also aware of the engine’s redline as well as its various gear ratios, there are many distinctive, adaptable shift programs that are functional.

Shifting Problems With An Automatic Transmission

Because of the heat and friction created by the multiple components that operate, the gearbox experiences greater wear and tear than most other vehicle parts.

The reasons which derive transmission hesitation upon acceleration are also diverse, including:

  • Transmission overheating
  • Torque converter failure
  • Filthy gear oil
  • Clogged gear filter
  • Transmission solenoid failure
  • Problems with the valve body
  • Burnt clutch disc
  • Rusty gears
  • An electrical issue exists in the transmission control module (TCM)

Aside from that, your automatic transmission fluid level is also one of the most particular circumstances to take into account.

Several gearboxes nowadays feature a dipstick that assists you in monitoring this horizon. Thus, the work left is absolutely tricky-free to get done.

All you have to do is merely take note of the transmission fluid’s color and smell for a burned odor.

Just two times a year, and that’s all needed for preventing any onward extravagant restoration.

Maintenance Tips

Here comes the in-depth details to keep your automatic transmission away from the case where manual transmission revs but doesn’t accelerate

Tracking The Transmission Fluid Again And Again

Such a tip has shown up quite a lot during this topic regarding manual transmission slipping when accelerating, but it is actually worth the stab, and you’ll know that.

So, how exactly to check up on the transmission fluid quality?

Seeing whether its level is too flat will be the earliest step, to begin with. If so, you may want to fill it with additional fluid.

As bad as what happens if you overfill power steering fluid, the worse situation is if this occurrence happens too often, then perhaps the system has already been attacked by a leak that can only be mended by a skilled mechanic.

The sign of it is usually dark red coloured transmission fluid, completely different from normal engine oil, which is in mild-brown color.

Be Sensitive To What’s Wrong With The Functions And The Sounds

The transmission system can be extremely delicate and sophisticated. Something that you thought of as a small fault is possible to snowball into a huge one at any chance.

Hence, by sensing the failure of the sounds and the functions susceptible, you may somehow foresee their crises and handle them better.

Quit Bad Driving Habits That Put Unnecessary Strain On The Gearbox

This reason for automatic transmission slipping when accelerating is because unstable shifting can trigger the gearbox to heat up and cause rubbery elements such as vital gaskets and seals to run aground.

Hence, lousy driving behaviors such as racing, towing heavy loads, rocking your car out of a snow bump or a pothole, and so on can be of no benefit at all to your transmission.


Can A Torque Converter Cause Delayed Engagement?

Yes, it can. If your transmission won’t shift when accelerating, the torque converter may appear as one of the most likely culprits to blame.

Since a one-way clutch in the torque converter permits components to only rotate in a single direction, the car will not go into low or reverse gear if this section is not operating adequately.

Can A Transmission Cause Hesitation?

Yes, your transmission can be one of the top reasons that cause hesitation.

As such, slow, delayed, weak acceleration accompanies hard shifting gears, and whining, grinding, or humming noises when accelerating are the most feasible clues for you to get there faster.


Annoying delayed shifting when accelerating is something abiding and yet not at all easy to get rid of.

It is completely incomparable to other manifest damages that can get dealt with by determining only a few causes.

Once you don’t get it fixed right, you get yourself into a pitiful infinite loop that eventually has no cure.

Hopefully, this article can somehow be of use to your issue. See you then!
