> **Quick Answer:** Yes, call a tow truck. Transmission slipping combined with violent shaking means the transmission is failing under load, and every mile you drive risks turning a repair into a full replacement. Pull over safely, turn on your hazards, and get it towed to a transmission shop. Do not limp it home.
## My Car Is Slipping and Shaking at the Same Time. What Is Actually Going Wrong?
Your transmission is losing its grip on the engine's power output. When a transmission slips, the clutch packs or bands inside the unit are no longer holding the gear, so the engine revs up but the car does not accelerate to match. The shaking you feel on top of that is the drivetrain lurching between engagement and slippage, which puts violent stress on the transmission output shaft, the torque converter, and the driveshaft all at once.
Common causes at this stage: low or burnt transmission fluid, a failing torque converter, worn clutch packs, or a solenoid pack that is no longer controlling fluid pressure correctly. The shaking usually means it has moved past "early warning" territory. The torque converter in an automatic can fail suddenly and lock up or disengage completely with no further notice.
## Is It Safe to Keep Driving If the Transmission Is Slipping and the Car Is Shaking?
No. Stop as soon as you can safely pull over. Driving a slipping, shaking transmission does not just risk more transmission damage. When a torque converter fails completely, you can lose the ability to move at all in live traffic. If a planetary gear set inside the transmission sheds material, that debris circulates through the entire unit and turns a $1,500 repair into a $4,000 rebuild or replacement.
If you are on a highway, signal, slow gradually, and exit or reach the shoulder. Do not make hard throttle inputs trying to clear the shaking. Keep speed low and steady until you can stop. Once parked, leave it there. See [car shaking violently at highway speed](/car-shaking-violently-at-highway-speed-safe-to-drive/) for more on what violent shaking at speed actually means for your drivetrain.
## How Much Will a Tow Cost for This Situation?
A local tow, say under 10 miles, typically runs $75 to $150. A mid-range tow of 15 to 30 miles will usually land between $125 and $250 depending on your location and the towing company. If you are on a highway and need a flatbed, expect the higher end of that range, since transmission issues usually call for a flatbed rather than a wheel-lift to avoid stressing the drivetrain further during transport.
If you have roadside assistance through your insurance, check your policy before you call a private tow company. Many policies cover a set number of tows per year or up to a specific dollar amount. Check your coverage first; a tow for a transmission job is exactly what that coverage is for. If you are unsure what your insurer covers, [GEICO's towing coverage after breakdown](/does-geico-cover-towing-after-breakdown/) and [State Farm's roadside towing policy](/does-state-farm-roadside-assistance-cover-towing/) are worth reviewing for how these policies typically work.
## What Do I Tell the Tow Truck Driver?
Tell them the transmission is slipping and the car was shaking under acceleration. That tells the driver to use a flatbed rather than a wheel-lift or dolly, because towing an automatic transmission vehicle with the drive wheels on the ground can cause additional damage if the transmission fluid is not circulating. Most experienced drivers will already know to use a flatbed for a transmission issue, but confirm it before they hook up.

Also tell them where you want it delivered. Have a transmission shop in mind before the truck arrives. A general mechanic can diagnose the problem, but for a rebuild or replacement you want a specialist. If you are stranded in an unfamiliar area, ask the tow driver. They deal with shops daily and can give you a straight answer on who does quality transmission work locally.
## What Should I Do Right Now While I Wait for the Tow?
Get completely off the road. Hazard lights on immediately. If you are on a highway shoulder, get out of the car and stand behind the guardrail if there is one. A breakdown on a high-speed road is a genuine safety hazard, and staying in the car on a narrow shoulder puts you at risk from passing traffic.
If it is hot outside, you can run the engine at idle for air conditioning, but do not attempt to move the vehicle under its own power again. Note the nearest highway exit or mile marker so you can give exact location to the tow company. On interstates, call 511 for road condition information or use your state DOT's traffic app to check if there is a dedicated breakdown lane or a nearby emergency call box.
Once the tow is en route, check whether your situation puts you in [limp mode](/car-wont-go-over-30-mph-limp-mode/). Some transmissions default to a single fixed gear when the control module detects a fault, which is why your car may have suddenly topped out at 30 mph before the shaking got worse.

## Common Questions
**Q: Can transmission slipping cause the check engine light to come on?**
A: Yes. The transmission control module monitors gear ratios and fluid pressure. When slippage is detected, it sets codes like P0700, P0730, or a range of solenoid-related codes. If your check engine light is on alongside the slipping and shaking, scan it before authorizing any repairs.
**Q: Will adding transmission fluid fix the slipping and shaking right now?**
A: If the fluid is critically low, topping it off might reduce slipping temporarily, but it will not fix whatever caused the fluid to be low in the first place. If the fluid is burnt (dark brown or black, smells scorched), adding fresh fluid does nothing useful. Still get it towed; driving on it risks the whole unit.
**Q: How much does a transmission repair or replacement usually cost?**
A: A solenoid replacement might run $200 to $500 in parts and labor. A rebuild typically costs $1,500 to $3,500. A full replacement with a remanufactured unit can hit $3,000 to $5,000 depending on the vehicle. That spread is exactly why early diagnosis matters. Driving further when it is slipping pushes you toward the high end.
**Q: Can the car shake from something other than the transmission if it is also slipping?**
A: Yes. A failing torque converter, a damaged driveshaft U-joint, or a broken motor mount can all produce shaking that feels like it is coming from the drivetrain. But if you are also getting transmission slip (engine revs without acceleration), the transmission is involved. Get a full diagnostic, not just a fluid check.
**Q: Does my insurance cover a tow for a mechanical breakdown like this?**
A: Only if you have roadside assistance coverage added to your policy. Collision coverage does not apply here since this is not an accident. Log into your insurance app or call your insurer before calling a tow company. Many plans reimburse you after the fact if you pay out of pocket, so keep the receipt either way.
