Re: car doesnt shift
Expensive ?? Yes so try a Salvage yard and easy to fix Yes. It's located on the passenger side fender just back ot the head light with a large wire harness attached to it. Check the harness for any corrosion and the fuses under the dash, drivers side. The other thing to is a bad VehicleVelocity Sensor (VVS) so double check the DTC Codes. The VVS is easy to replace and cheaper then a new TCM. Good luck and hope this helps. Keep me posted ne glad to help.

P0700 is simply the ecm recognising that the tcm (tranny) has an error code stored/registered. The one to worry about is your p0733 code. This code means the tcm detected a gear ratio error in third gear. There's 5 main possible causes. Simple/cheap -> expensive/difficult. .. Low or dirty ATF. Add fluid if low or change fluid and filter If burnt smelling or dirty/discolored. Shifting solenoid . Check or have tested the shifting solenoids . They control fluid flow and transfer to various clutch packs for gears. Hydraulic control circuit and mechanical failure. Both of these require full rebuild. Control circuit is expensive and hard to get to . Mechanicalso is usually either a worn out/pourly adjusted clutch pack causing the gear to slip or a failing torque converter.
P0732 FORD - Incorrect Second Gear Ratio Transmission in second gear and the ECM detected an incorrect gear ration. This diagnosis monitors actual gear position by checking the torque
converter slip ratio calculated by Transmission Control Module (TCM) as
Torque converter slip ratio = A x C/B
A: Output shaft revolution signal from revolution sensor
B: Engine speed signal from Engine Control Module (ECM)
C: Gear ratio determined as gear position which TCM supposes
If the actual gear position is higher than the position (2nd) supposed
by TCM, the slip ratio will be more than normal. In case the ratio
exceeds the specified value, TCM judges this diagnosis malfunction.
Symptoms - Engine Light ON (or Service Engine Soon Warning Light) - Incorrect transmission shifting
A 2002 is not an "older car".
You should easily be able to get 15 years out of any decent car.
But the PCM and TCM are not likely bad.
First start with a simple tuneup, with plugs, wires, etc.
Then you try diagnostics on the fuel injection, such as temp, O2, and air mass sensors, as well as filter, fuel pressure, etc.
Then check things like ERG valve, fuel vapor purge valve, etc.
The last thing you do is give up and buy new control modules.
The TCM is stuffed up in the drivers side dash just left of the steering column on this disposable vehicle. There are 2 modules there. One is a pcm and the other is a tcm. The onewith the large single black plug is the TCM.
