fuuu ****** up my truck

here's everything rele:vant I can think of

-installed Volant on Friday
-tuned 91 performance tune from 5star with update for the volant
-went offroading today, at the very end of the offroading I get a CEL on dash
-check CEL, code was p0657, and transmission stuck in 3rd gear
-tried clearing code with the SCT tuner, it came right back
-drove home 50 miles and checked codes again, got p0740, p0750, p0755, p0760, p0765, p0770
-reset tune to stock, no help
-reset KAM, no bueno

now what do I do

I did not go offroading today I got No problems. You had way more fun. Somebody give my man parts to someone else.

Simple answer. Don't get a tune or **** with shit that causes PCM issues. Hope it all works out.

P0657 Actuator Supply Voltage "A" Circuit/Open, I'm gonna say you lost power to your transmission control module in some way, which caused all the other codes you're experiencing, make sure you have your dealership focus on the p0657 code if you're going to have them work on your truck

The rest of the codes are shift solenoid malfunction codes, they aren't the cause of your problem, just a symptom

makes sense

Sometimes after you install a Tune it helps to disconnect the battery to force the PCM to start a new learning cycle.


But with all those error codes something else might be going on.

P0740 Torque Converter Clutch (TCC) solenoid TCC solenoid circuit/open The PCM detected that the TCC solenoid control circuit failed open. MIL ON
TCC is disabled
DTC P0743 may set
GO to Pinpoint Test
P0750 Shift Solenoid A (SSA) SSA The PCM detected that the SSA circuit failed open or shorted to power. MIL ON
5th and 6th gear only
DTC P0753 may set
GO to Pinpoint

P0755 Shift Solenoid B (SSB) SSB The PCM detected that the SSB circuit failed open or shorted to power. MIL ON

Seems to all point to the Torque conveter

The tunes and other modifications have nothing to do with jb's truck failures, he's most likely having a wiring failure
