check engine light on after motor/trans mods
I have these codes on after dropping a 5.3L in my truck with a 224/224 cam, 3600 stall, longtubes, transgo hd-2, and vette servo
P0740-TCC circuit malfunction
P1810-TFP valve switch malfunction
P2761-TCC controler 1 circuit open.
Before I tow it to Don@slowhawkperformance to tune it, i would like to resolve these issues so i dont waste his time, nor my money.
Did anyone else run into these? solutions? right now my truck stalls out. the video of that is here:

oh and it should also be known that the wiring harness for the truck is from a 4wd, not 2wd. everything is unplugged and no "service 4wd" is on

still have these codes, I checked to make sure I have voltage at the transmission plug and verified the 250K impedance through the wiring.
next step is dropping the pan to check out the wiring inside, unless Im suppose to just tune this out

any suggestions on where to start? im thinking about dropping the pan and checking the connections on the valve body. Its the only thing i touched. the trans has 55k miles on it and was 100% fine before i put the converter/servo/hd-2 kit in

First post here, but i thought i would chime in. According to my chiltons your codes are....
P0740 - Torque converter clutch enable solenoid circuit
P1810 - Trans pressure switch assembly malfunction
P2761 - (was not listed)
Im not sure if that really helps or not you listed pretty similar causes. good luck.

yeap. my truck was a bottom of the line V6 with crank windows. now its got a v8 with power everything. every harness was changed. even the chassis harness because the fuel pump was different (returnless now)
for an update, i went out to the garage yesterday in preperation of removing the pan, i checked the codes and none of the transcodes were there. i drove it around the block, everything is fine. i just need to figure out the fan harness and have the other codes shut off. the only problem it has is when the torque converter locks up the truck shakes. not sure if this is because its a 3600 stall with 3.42s or if the line pressure is wrong. i checked the codes after it happened and nothing popped up. its also a brand new converter so i cant see it being that
heres a vid for you guys of some of the progress
