Dave, The P0700 code is a generic fault code indicating the the TCM (transmission control module) has recognized a problem and the P0755 is the indicated problem. I'd recommend you check your transmission external electrical connector for water intrusion and corrosion at the terminals by disconnecting the connector. If nothing appears wrong, I'd then recommend you drop the lower transmission pan and take a look at the residue deposit that is laying on the bottom of the pan. You should only see a relativily minor amount of grayish, black clutch material residing there. Pay particular attention for a gross amount of this or any large particular material, including any metal, either filings or chunks, or any brass or aluminum. If this checks out to be fairly clean, then I'd recommend you replace that "B" solenoid (2-3 shift solenoid) and have the trans. pan and filter replaced.; I'd also highly recommend you have the trans flushed for anyother particular matter that may reside internally inside the transmission. You'll have to have the codes cleared and the transmission relearned for shift feel, at that point.

It's in limp home mode. You'll have to check wire connections and electronic controls. If it has a vacuum modulator you can remove it and look for trans fluid on the vacuum hose side (meaning ruptured diaphram). Double check the parts you replaced as well, especially if they were used parts. My dad went through three speed sensors in one year on his Caravan. You should drop the pan after checking other components. It could be a bad relay, shorted module or wire. The three speed transmissions are much more reliable than the four speed overdrive transmissions but with age and miles things can go wrong and parts will wear out.

sorry to say trans is fried.
Consider a used trans from the bone yard
or a rebuilt one.
An independent auto shop is likely to give you a fair price!!!!!!!!!!!!!!!!!!!

SOURCE: Error Codes P0700 and P0605

0605 is for an Internal Control Module Read Only Memory (ROM) Error. This is typical of a malfunctioning computer. If the computer is bad, your retrieved codes are probably wrong anyway. May need to replace computer, drive, then see if if your check engine light returns.

1997 honda accord tranmission problem code p0700 drive 4 flashes


Many vehicles have a control module for the automatic transmission called a transmission control module (TCM). The engine control module (ECM) communicates with the TCM to monitor the automatic transmission for faults. If the TCM detects a fault in the automatic transmission and sets a transmission related fault code, the ECM is informed of this also and sets a P0700 in the ECM memory.
This illuminates the Malfunction Indicator Lamp (MIL) to let the driver know there is a problem. If this code is present and the MIL (Malfunction Indicator Lamp) is illuminated that basically means there is at least one transmission code set in the TCM's memory. P0700 is an informational code only. It doesn't point to a direct fault in the engine, only a general fault in the transmission. More diagnosis is necessary to identify what the transmission fault is. This requires a scan tool that will communicate with the transmission module.

Symptoms Symptoms of a P0700 DTC may include:
  • Malfunction Indicator Lamp (MIL) illumination
  • The transmission may exhibit drivability problems like slipping, etc.
Causes More often then not, the cause of this code is that there is a transmission problem of some kind. The TCM detected the problem and set a code. P0700 means that a fault code is stored in the TCM. However this doesn't rule out the possibility of a failed PCM or TCM (unlikely).
Possible Solutions For a P0700 the only real solution is to acquire a scan tool that will communicate with the transmission control module. Extracting this code from the TCM will be the first step in repairing the fault in the transmission.
If the TCM compatible scan tool will not communicate with the Transmission Control Module then that is a good indication that there may be a fault with the TCM itself.

What is the code p1684 and p700


The P1684 code means simply that the battery has been disconnected within the last 50 starts, You can effectively disregard this unless you know that to be false. Then it could be an indication of an impending battery failure.The P0700 code is more troublesome. I collected this information from another source:

What does that mean? Many vehicles have a control module for the automatic transmission called a transmission control module (TCM).

I have a 2001 Elantra GT. with the auto trans in drive the trans slips when I'm doing 50-65 mph and the trans is in 4th gear if i have my foot to heavy on the gas. it doesn't do it as bad if I have...


First of all, Hyundai Transmissions use a 'specific' fluid called 'SPIII' and ONLY SPIII. Any other fluid doesn't meet Hyundai's specification and can cause 4th gear slippage (which is the TTC - Torque Converter Clutch - frequently referred to as the "lock-up" converter). You should have had a Check Engine Light. The problem you describe regarding 'doesn't drop back to first when I'm at a stop' sounds like the transmission has gone into 'Fail-Safe' mode because of the 4th gear ration incorrect. In "Fail-Safe" mode, the trans stays in 3rd gear until you cycle the ignition key off, and then back on. You need to scan your engine's computer to see what/which trouble codes have been set/stored in it. You'll need an OBDII scanner to read any codes that might be there. When a 'check engine light' (MIL=Malfunction Indicator Lamp) is turned on, there is a DTC (Diagnostic Trouble Code) set/stored in the ECM/PCM (Engine Control Module/Powertrain Control Module). This code identifies which engine management system component/function experienced a malfunction. Once you pull/read this/these code(s), you can begin diagnosis.

While some people will tell you to change or flush the transmission fluid and see if it gets better. I would like to warn you it probably won't help much on your car. The Hyundai's transmissions have a high failure rate and the fluid changes and repair in a bottle fixes won't change anything. Just check if the fluid level is correct and make sure that the wires that go to the transmission are on clean and tight with no burns or shorts. Remember the transmission shifts gears based on info from the TPS sensor and a speed sensor. So if the CEL was coming on and you didn't scan the computer, it might just be a bad sensor and not the transmission. Take it to a Hyundai dealer not a Transmission shop.
