4l80e swap, 02 Yukon, Limp Mode, no DTC, repinned, segment swapped, I'm stumped
As the title says, I have an 02 Yukon where I'm trying to swap the 4l60e with a 4l80e.
I'm stumped.
4l80e was rebuilt entirely. New everything including solenoids. Internal dual feed mod, Sonnax Sure Cure AFL kit, pump drilled to prevent seal push out.
Attached are the files I used. Stock, Segment Source and Current file starting with Read_2_Seg...hpt
Can someone review my Read_2_....hpt tune?
VSS in front and rear both read seemingly proper values.
I've run diagnostics on the solenoids and here are the results.
---------------
12v verified at pin E on PCM to trans connector.
1-2 solenoid 20ohm, A, OK, clicks with 12v
2-3 solenoid 21ohm, B, OK, clicks with 12v
PCS, pressure control solenoid 4ohm, Force Motor, OK
TCC solenoid 10ohm, OK
Temp sensor 4k ohm, OK
---------------
On stands I...
Tried to force shifting like so, stuck in 2nd:
Tried to drop to first by playing with 1-2(A) and 2-3(B) Solenoids. ON-OFF combo should drop to first, right? No dice! Calculated ratio confirms no shift and still in 2nd.
I even supplied 12v to the trans and forced 1-2(A) to ground and no 1st gear or change of any sort.
Here are the DTC I've enabled on first MIL: DTCs (P0500, P0608, P0700 to P0724, P0740 to P0757, and P1504)
I could really use some input. I'm stuck. This is my first swap ever and I've tried to do my homework!
I verified the input VSS is working. I read that if it wasn't then the trans goes into limp mode. I disconnected it, got 0 rpm on input VSS log and caught a DTC immediately.
