New member question about pimpxshift

New member don’t know if this is the right thread but bought a pimpxshift ecu struggled to install it, had problems with the transmission staying stuck in 3rd gear on drive and would work normal in gear 2, overheated the transmission and messed it up, just got a fresh rebuild but it is still having same issues, mechanic told me to check the ecu and wiring harness because everything under the truck seemed to be working properly, been on the stinger pro boards and now looking for answers here too thank you
 
Did you change the supplied transmission tune at all? If not, it has to be in the wiring. Have you double-checked the wire colors vs the pin location for the wires that had to be moved?

What year truck?
 
Followed the instructions pretty well, will go back and take another look at the pins I moved again, wesk helped me mess with the voltage on the gear position and stuff like that but other than that I haven’t messed with it, trying to figure out my issues currently but pro boards answers takes a while, do you also know how to make the temp gauge for the transmission work I’ve messed with the thermistor table but nothing changes

Alberto, there is nothing AT ALL that needs to be changed in the tune, thermistor tables etc. Please give us information about your truck, any wiring changes, etc, etc.
 
1992 Ford F-150 347 stroker rebuilt E4od, only repined wires as shown in the instructions and video from stinger only problem is for pin 5 for the transmission clutch coast-drill accidentally barely scraped it but seems to be good and also won’t fully lock in, pin 18 for the trans temp wouldn’t fully lock in either, harness did get some humidity because of the rain in Texas but fully dried it before doing anything else don’t think that would be a problem because truck turns on fine

Problem is truck won’t move on it’s own power in drive like if it is stuck in another gear, when I put it into 2 or reverse it moves perfectly fine
Transmission shop rebuilt the transmission and checked the signal from the shift solenoids and said everything was good that I should focus on the ecu. Wesk did walk me trough changing the voltages on it and it did help but not that much

This problem caused the transmission to overheat and mess up so really frustrating going trough this hopefully joining the nloc will help
 
tune im using

below is the tune im using,wont let me add datalog of it

What year is the E4OD and what did it come out of? I thought you had a Lightning when I recommended you to the site. Good bunch of guys here, hopefully they get you sorted.

There is a setting you have to change to make the trans temp read correctly but I don’t remember what it was. I never had any trans related issues after the swap.

So the trans functioned normal before swapping to the pimpXshift?
 
I think the first thing I'd do is unhook the wiring at the transmission and see how it behaves. You will have reverse and 1st and 2nd if you manually select them (in D you'll only have 1st). The transmission will shift into those gears very hard. But it will at least tell you if the problem is electronic or mechanical. You really only need to pull the control plug (passenger side), but I'd pull both and give them a really solid inspection. Also check the connectors on the inner fender.

I'll have to look up the value to change for temperature when I get home. You have to scale the transmission temp thermistor to the Ford values (which should be selectable from a dropdown). Keep in mind this only changes what you see on the TunerStudio screen; it doesn't change what the ECU sees - it doesn't need to.

The TunerStudio screen for the transmission will show the solenoid states as well.
1st gear : Solenoid 1 On, Solenoid 2 Off
2nd gear: Solenoid 1 On, Solenoid 2 On
3rd gear: Solenoid 1 Off, Solenoid 2 On
4th gear: Solenoid 1 Off, Solenoid 2 Off
 
Yeah I’ve always posted on the lightning page it is way more helpful than the regular obs page,So it is the original e40d from the factory just got the transmission rebuilt,shop tested everything under the truck and everything seemed to be perfect mechanic told me to figure out what’s going on with the ecu

- - - Updated - - -

I’d rather avoid the mechanical test because the transmission was working amazing before the ecu swap and it was just rebuilt so shouldn’t be any issues with it mechanically
 
If you're dead certain it's not mechanical, it has to be the wiring. You'll have to retrace your footsteps. All of them. You can't just say, "I did it right."

In my opinion, you're going to want to primarily make sure that Pin 52 moved to Pin 54 cleanly.

If it were me, I would still check the wiring harness at the solenoid pack (passenger side) on the transmission and be sure there are no bent pins or crud in the connector.

Start the truck and put it on jackstands like the instructions say. You did do this, right, and made sure that it ran through the gears before driving it? Take it through the gears and watch the TunerStudio transmission screen to be sure that the solenoids are being asked to do what they're supposed to.

Yes I did the process multiple times, wesk explained very well, but didn’t make a big difference, Shannon from stinger told me to test the resistance on the pins but I’m still trying to figure out where exactly to place the multimeter, I also went over the wiring and I did do it correctly as shown in the instructions
 
He told you in the post. Check resistance against pin # (I don't remember the number.) Post here what he told you to test please.

Wesk had told me a few months ago to Check the resistance of the following pins to pin 57 (ecu unplugged):
54
19
38

Im still trying to figure out how to check it, don’t know where to place multimeter and how many ohms it should be putting out if it’s good
 
Measure Resistance with Multimeter

Using a multimeter to check for resistance is a much simpler task. The test leads will be kept plugged in the same sockets as for the voltage checks, but the selector switch will need to be turned until it points to the ”horseshoe” resistance symbol.
Touching the probes across the device whose resistance is to be measured, the meter should properly display the resistance in ohms:
[data:image/svg+xml;charset=utf-8,<svg height="399px" width="610px" xmlns="http://www][https://instrumentationtools]
One very important thing to remember about measuring resistance is that it must only be done on de-energized components! When the meter is in ”resistance” mode, it uses a small internal battery to generate a tiny current through the component to be measured.
By sensing how difficult it is to move this current through the component, the resistance of that component can be determined and displayed. If there is any additional source of voltage in the meter-lead component-lead-meter loop to either aid or oppose the resistance-measuring current produced by the meter, faulty readings will result. In a worse-case situation, the meter may even be damaged by the external voltage.

ok so before i did anything i checked again under the trans, next to it is a plug that goes in both ways. i flipped it over and sure enough the trans temp gauge started working and i put the truck in drive and it launched in first gear and moved on its own power perfectly, took it out for a drive and it went into first and second without a problem but wouldn't go into 3 and 4

so now im trying to figure that out truck ran perfectly fine temp went up to 120 but it wouldn't change into 3 and 4
