Limp mode?

Maybe you misunderstood, the pins I checked where on the Tcm not PCM and there are in fact 60 pins, 56 is fused b+, 57 is ground and both checkout iv added the diagram of TCM harness

OK so here's an update, I've changed the tcm, when I was finished I started the van and no light came on, I went for a test drive and as soon as it was suppose to shift, the light came on. This time I got p0755 along with the other two codes, I changed the shift solenoid which was associated with p0755 and no luck, I started checking for wires and found that on pin 19 of the tcm, it is the shift solenoid 2-4 wire, I have no power at TCM but I have it on the solenoid harness. Any thought. And thanks for your help I really appreciate it, I've been to aamco and a couple of other shops, they all say the same thing and wanna hand me a big bill, believe I personally would love to just get it fixed but unfortunately that option is not available to me, thanks for bearing with me

I got the TCM Used, I did check the relay and fuse #15 20a, they are both ok, the wire at pin 19 on the TCM harness is for: 2-4 shift solenoid, that wire has low amps coming out of the TCM but it has good amps on the solenoid harness, could there be a break in between? Does that wire go from tcm to the IPM first and then to solenoid? Again thank you for the input.

OK I have a multimeter, with the dial on 200 0hms, I tried testing pin 19 at the TCM(which is 2-4 solenoid control) and pin 8(2-4 solenoid control) at the solenoid wiring harness and didn't get any reading, am I checking the right wires? Am I on the right setting for the multimeter? Or am I right and that wire is broke? Again thank you so much I feel that I'm inches away?

Hey, Just thought I should update this: I did find and repair the problem, the 2-4 solenoid wire (#8 on the solenoid pack)(#19 on TCM) was corroded at about the center of the harness, I replaced with a 14 gauge wire by cutting approx 1 inch of the corroded area. The van is now shifting fine and no codes are followed, will update in a couple days if any problems occur, just wanted to say thanks for the help!

Also screw a multimeter, a test light gave me the fix, the multimeter wouldn't even get a reading.

I believe the problem is related to the etax circuit. Possible wiring issue as with a test light and a multi-meter. I have done a small amount of diagnosing in the fuse panel under the hood. Did some testing on the etax relay circuit. I have desperately been trying to find a wiring diagram for this circuit in order to trace the wiring and identify which wires are what. I am a pretty knowledgeable mechanic I just do not have the time to take it to the shop and I do not have one of those scanners that will tell me what exactly is going on transmission wise on the other hand I do realize the issue could be related to the solenoid pack itself internally, but I figure if I could trace it down without taking something apart first that may be a little easier. I just cannot seem to find it wiring diagram for the etax circuit.

Stuck in limp mode. Does not shift into third. I have found that from 2001 and up this has been a consistent issue dir these vans. On the Etax relay circuit the side that is meant to receive constant twelve volts one side has twelve volts and the terminal above that one reads less then twelve. This was done with a jump. I apologize. I do not have the relay in front of me to tell you what the pin numbers are. I am at the moment assuming a harness or wiring problem. Maybe corrosion. Thank you so much for the information I will post once I have more information.

Van was driving like brakes were on, right front brakes started smoking. Stopped, backed up, pulled forward an few times, seemed to loosen up. Went by a Firestone store as were we desperate and 40 miles from home. They said brakes were turning, but both front calipers were hot.. They wanted $1000 to fix didn't say what caused the problem. Did nothing drove home. Next day went to drive after about 15 min, trans went to limp mode. Started for home and them remembered to restart it and it cleared the limp mode and drove ok home. Haven't driven it since. Can the front brake problem cause the limp mode?Check engine light is on, no ABS light. Front brake were rebuilt about a year go with new rotors and pads.
