My dodge grand caravan today threw a 700 engine code transmission module, car wont go over 25 and only has powered acceleration for first 5 seconds car is on.


700 is a generic transmission code. It went to limp mode, that's why it drives like it does. Have the codes read with a newer /better code reader or a scanner. Find out what other codes are in there.

The RPM of my engine remains at 4000 while my speed is 120 km/hr


I guess that you have a manual transmission. If that is the case you have a clutch on the way out. Slow slippage that gets worse as the plate gets hotter. If an automatic it is possible that the overdrive is not holding due to low pressure in the box. Have a pressure test done on the box--- have the fault codes read. From experience 120 kph is around 3200rpm for most cars and the 800 rpm difference indicates that the o/dive is not working as it should.

DEFINITE LURCH IN 1ST AND 2ND GEAR,


This may apply. ...............................

Carry out the adaptation drive cycle road test:

Note: This process must be carried out in normal mode (not sports mode). On a flat road, the transmission fluid temperature must be above 60° C (140° f) and below 100° C (212° f) (vehicle at normal operating temperature will ensure that the transmission fluid temperature is above 60° C (140° f)).
9. Accelerate from rest with light throttle (do not exceed the upper rev limit in appendix 1). 1-2, 2-3, 3-4 shifts must occur with engine speed between the following limits:.
Note: Do not move the accelerator pedal during shifts.

• 3.0L VIN ALL 1800 - 2000 rpm
• 4.2L N/A Prior VIN M96321 1450 - 1600 rpm
• 4.2L N/A From VIN M963221550 - 1700 rpm

10. Continue to accelerate gently to 50 mph (80 km/h) so that transmission shifts into 5th gear.
11. Go into overrun and let the transmission shift down into 4th gear without braking.
12. Brake gently to a standstill and hold footbrake on for at least 15 seconds.
13. This process should be carried out at least five times.

RPM drops to zero at idling after engine accelerates when warm


This may been an ignition module or a MAF sensor, this car may need to be diagnosed using a OBD I computer code reader to accurately diagnose the problem.

It could be a spark plug, plug wire, or a coil. Sometimes thay break down intermittently. If it needs a tuneup, that would be the first thing to do.

2001 grand caravan high rpm at 70 mph


It sounds like the last gear in your transmission may not be engaging. Caravans are actually famous for tranny problems. Furthermore, be sure to check your transmission fluid while your vehicle is idling. That ensures accuracy. But you may have to get someone to physically look at it to ensure your problem gets solved. Kind of risky diagnosing something so big through typing.

GM service engine code P1870/2000 GMC Sonoma 2.2 cylinder


you jave a biggie here.
here is some info
CIRCUIT DESCRIPTION
The Powertrain Control Module (PCM) monitors the difference between engine speed and transmission output speed. In D3 drive range with the TCC engaged, the engine speed should closely match the transmission output speed. In D4 drive range, with the TCC engaged, the TCC slip speed should be -20 to +60 RPM .

When the PCM detects excessive TCC slip when the TCC should be engaged, then DTC P1870 sets. DTC P1870 is a type B DTC.

CONDITIONS FOR RUNNING THE DTC
  • No TP sensor DTCs P0122 or P0123.
  • No VSS assembly DTCs P0502 or P0503.
  • No TCC solenoid valve DTC P0740.
  • No 1-2 SS valve DTC P0753.
  • No 2-3 SS valve DTC P0758.
  • No 3-2 SS valve assembly DTC P0785.
  • No TCC PWM solenoid valve DTC P1860.
  • The engine is not in fuel cutoff.
  • The engine torque is 40-400 lb ft .
  • The TP angle is 12-50% .
  • The vehicle speed is 56-112 km/h (35-70 mph ).
  • The speed ratio is 0.64-0.95 (the speed ratio is the engine speed divided by the transmission output speed).
  • The engine speed is 1500-3500 RPM .
  • The gear range is D4.
  • The commanded gear is not 1st gear
  • The TFT is between 20-130°C (68-266°F) .
  • The shift solenoid performance diagnostic counters are zero.
