Is P0700 a Dodge PCM or transmission problem?

It depends on the companion codes. If P0700 appears with P0601 or P0606 on your Dodge, the PCM has failed. If it appears with solenoid codes like P0750 or P0760, the transmission internals are the issue.

Can I drive my Dodge with P0700?

Your Dodge may be in limp mode — stuck in second gear with no overdrive. You can drive short distances but continued driving risks further transmission damage.

How much does it cost to fix P0700 on a Dodge Ram?

If the Dodge PCM or TCM has failed, dealers charge $1,000 to $2,000+. Quality PCM sells pre-programmed Dodge PCMs and TCMs starting at $200 to $400.

P0700: Transmission Malfunction — Dodge & Ram

Q: What does P0700 mean on a Dodge?

P0700 on a Dodge means the Transmission Control Module has detected a fault. It's an informational code — you need to read the companion transmission codes to find the actual problem. On many Dodge vehicles the PCM and TCM are integrated, so P0700 can indicate PCM failure.

What Does P0700 Mean on a Dodge?

Code P0700 on a Dodge is an informational code from the Transmission Control Module (TCM). It means the TCM detected a transmission fault and flagged the check engine light. P0700 doesn't tell you the specific problem — it tells you to read the transmission-specific codes stored alongside it.

Here's what makes P0700 important on Dodge vehicles: many Dodge models use an integrated PCM/TCM, meaning the same module controls both the engine and transmission. When that module fails, you'll often see P0700 paired with PCM failure codes like P0601 or P0606.

P0700 Symptoms on Dodge Vehicles

Check engine light on your Dodge, often with the transmission temp light
Harsh or delayed shifting — very common on Dodge Ram trucks with the 45RFE and 545RFE transmissions
Dodge stuck in limp mode — locked in second gear, no overdrive
No overdrive on the highway — Dodge engine revs high at speed
Transmission slipping between gears on Dodge Caravan and Grand Caravan
Dodge won't shift out of park in severe cases

What Causes P0700 on a Dodge?

P0700 is always accompanied by other codes. The companion codes tell you where the real problem is:

Failed Dodge PCM/TCM — the integrated control module can't manage the transmission. Common on Dodge Ram, Durango, and Dakota.
Faulty shift solenoids — the electrical solenoids inside the Dodge transmission wear out, especially on Dodge Caravans with the 41TE transaxle.
Dodge transmission wiring damage — corroded or chafed wires between the PCM and transmission. Road salt accelerates this on northern Dodge trucks.
Low or burnt transmission fluid — causing hydraulic pressure issues in the Dodge transmission.
Internal Dodge transmission damage — mechanical failure inside the gearbox.

Dodge Models That Commonly Throw P0700

P0700 is one of the most common transmission codes on Dodge vehicles. We carry both PCMs and TCMs for all of these:

Dodge Ram 1500, 2500 & 3500 (1996–2007) — especially with the 45RFE, 545RFE, and 48RE transmissions. The Dodge Ram 5.7L Hemi and 4.7L are the most frequent.
Dodge Durango (1998–2007) — common on 4.7L and 5.7L Durangos with the 545RFE.
Dodge Dakota (1996–2007) — frequent on 3.9L and 4.7L Dakotas.
Dodge Grand Caravan & Caravan (1996–2008) — the 41TE transaxle on the 3.3L and 3.8L is prone to solenoid and TCM issues.
Dodge Intrepid (1998–2004) — the 2.7L and 3.5L Intrepids with the 42LE transmission.
Dodge Stratus (1998–2007) — transmission control failures on the 2.4L and 2.7L models.
Dodge Avenger (1995–2008) — both PCM and TCM failures reported.

Is It the Dodge PCM or the Transmission?

Read the codes stored alongside P0700 on your Dodge. This table tells you where to look:

Codes on Your Dodge	Most Likely Cause	Fix
P0700 + P0601 or P0606	Dodge PCM has failed internally	Replace Dodge PCM
P0700 + U0100 or U0101	Dodge PCM/TCM communication failure	Replace Dodge PCM/TCM
P0700 + P0750/P0755/P0760	Dodge transmission solenoid failure	Replace solenoid pack or wiring
P0700 + P0715/P0720	Dodge speed sensor failure	Replace input/output speed sensor

How to Fix P0700 on a Dodge

Read ALL codes on the Dodge — use a scanner that reads TCM codes, not just engine codes. P0700 alone is meaningless without companion codes.
Check Dodge transmission fluid — should be red/pink, not brown or burnt-smelling. Low fluid causes most Dodge transmission symptoms.
Inspect wiring on the Dodge transmission — check the harness connector on top of the transmission for corrosion or damage.
Diagnose based on companion codes — see the table above to determine if your Dodge needs a PCM, TCM, or transmission repair.

Dodge PCM/TCM Replacement Cost

Repair	Dodge Dealer	Quality PCM
Dodge PCM Replacement	$1,000–$2,000+	$250–$400 (pre-programmed)
Dodge TCM Replacement	$800–$1,500	$200–$350 (pre-programmed)
Solenoid Pack	$300–$600	N/A — local transmission shop
