Chrysler Daytona Automatic Transmission Oil Pressure Switchs

Chrysler Daytona Automatic transmission oil pressure switchs

Starting at low prices, AutoBuffy stocks multiple automatic transmission oil pressure switches from top OE-quality brands. This sensor monitors hydraulic pressure inside the transmission and signals the PCM to trigger the transmission warning light or limp mode when pressure drops out of range. A failed switch causes false warnings, shift problems, or a no-start condition on some vehicles.

Signs your Chrysler Daytona needs a new automatic transmission oil pressure switch

  • Transmission warning light or CHECK TRANS light illuminates on the dashboard with no other obvious cause
  • Vehicle enters limp mode — stuck in a single gear — despite normal fluid level and condition
  • Harsh, delayed, or erratic gear shifts that appear or worsen after the transmission reaches operating temperature
  • Transmission fluid pressure-related fault codes stored in the PCM, such as P0840, P0841, P0845, or similar pressure circuit codes
  • Engine cranks but will not start on models that use transmission pressure confirmation as part of the neutral safety circuit
  • Automatic transmission slipping or hunting between gears under light throttle when fluid level and condition are known to be good

Which automatic transmission oil pressure switch should you buy for your Chrysler Daytona?

The right switch is determined by its thread size, connector type, and pressure rating — all of which are transmission-specific. Buying a switch matched to your exact transmission code matters more than brand alone. Your main decision is between OE-equivalent aftermarket parts and genuine OEM units.

OEM / Dealer-sourced switch
Best for
Owners who want exact factory specifications and connector fit
What you get
Precise pressure calibration, guaranteed connector compatibility, highest cost
OE-equivalent aftermarket (direct-fit)
Best for
Most daily drivers seeking a reliable, cost-effective repair
What you get
Matched thread pitch and pressure rating, plug-and-play installation, moderate price
Multi-function pressure switch (combined unit)
Best for
Transmissions that use a single switch to monitor multiple pressure circuits
What you get
Replaces several circuits at once, reduces future leak points, confirm fitment carefully
Remanufactured / reconditioned switch
Best for
Budget repairs on older or high-mileage vehicles
What you get
Lower upfront cost, inspected and retested internals, shorter warranty than new units

Replacing the automatic transmission oil pressure switch on a Chrysler Daytona

Moderate⏱ 30 minutes – 1.5 hoursSocket set or box-end wrenches (sized to switch hex)Transmission pressure switch socket (crowfoot or dedicated switch socket)Drain pan and shop ragsOBD-II scan tool for reading and clearing codesThread sealant or new sealing washer (if not included with switch)

Locate the switch on the transmission case or valve body — position varies by transmission. Disconnect the electrical connector, remove the switch using the correct socket to avoid rounding the hex, and install the new switch hand-tight before torquing it snugly to avoid cracking the case threads. Reconnect the connector, check the transmission fluid level, clear any stored codes, and confirm the warning light extinguishes on a short test drive.

Frequently asked questions

How much does it cost to replace automatic transmission oil pressure switches on a Chrysler Daytona?
Parts start at low prices at AutoBuffy. Add one to two hours of shop labor if you are not doing the job yourself. Total repair cost varies by transmission access and whether additional seals or fluid are replaced at the same time. DIY installation keeps overall cost closest to the part price alone.
Can I drive my Chrysler Daytona with a faulty transmission oil pressure switch?
Short distances may be possible, but it is not advisable. A failed switch can keep the transmission locked in limp mode, cause undetected low-pressure damage to clutch packs and solenoids, or prevent the vehicle from starting. Continuing to drive risks turning a simple sensor replacement into a costly transmission overhaul.
Will replacing the transmission oil pressure switch clear the limp mode on my Chrysler Daytona?
If the switch itself was the cause, yes — replacing it and clearing stored fault codes should return the transmission to normal shift operation. If limp mode returns after replacement, the underlying issue is low actual fluid pressure, a failing solenoid, or internal transmission wear rather than a faulty sensor.
How do I know if the switch is bad or if I actually have low transmission fluid pressure on my Chrysler Daytona?
Connect a scan tool and read live pressure data or fault code freeze-frame information. A dead or open-circuit switch typically sets a rationality or circuit code rather than a genuine low-pressure code. Confirm fluid level and condition first; if both are good and the code points to the circuit, the switch is the likely culprit.
How many transmission oil pressure switches does the Chrysler Daytona have?
It depends on the transmission. Many modern automatic transmissions use two to four pressure switches — monitoring circuits such as line pressure, reverse, overdrive, or torque converter clutch circuits individually. Check your vehicle's service information or use your year and transmission code in our fitment filter to see exactly how many your Chrysler Daytona requires.
Does the transmission oil pressure switch on a Chrysler Daytona require any programming after installation?
In most cases, no programming is required — the switch is a passive pressure sensor that either opens or closes a circuit at a set threshold. However, after replacement you should clear any stored DTCs with a scan tool and perform a short drive cycle so the PCM can confirm normal pressure readings and cancel any pending codes.
