I did a 411 PCM swap in an 89 camaro and I want to use the PCM to control the TCC on a 700R4. I have the TCC enable soleoid wire (pin 42) wired to the TCC lockup solenoid. I can command it to lock through the DVT page in the scanner but it wont lock by itself....anyhelp?
monitoring tstate9 says that the tcc is not locked due to cold transmission and due to range.
Can I put a resistor between pins on the ecm for the temp sensor...but what is the range error?
Yes, you can place a ressistor, look at this table: Attachment 8620
You may be able to place an engine ECT sensor someplace on the trans and use that (the ECT seems to have the same temperature-vs-resistance transfer function as the TFT sensor).
Joe I still get the tcc off due to range..what is this? I placed a resistor and the tcc off due to temp is off now..
I believe it has to due with pins c1-32, c1-34, c1-72, c2-62. In the harness 32 and 34 are connected to my shift lever switch which grounds them in park/neutral. What is needed for pins 72 and 62?
Do you provide a VSS signal to the PCM...?
You maybe do need:
- P/N Position switch input (C1-34),
- TCC Brake switch position input (C1-33),
- Manual Valve Pressure switch input (C1-17,18, C2-63).
In my schematic, C1-32 is Clutch Pedal Position (i.e. manual trans)...?
I don't see c1-72, c2-62...
what vehicle/year/model schematic/harness are you using...?
The word range refers to the range indicated by the manual valve position pressure switches (3 or 4 switches depended on car/truck application).Quote:
