Ok I have searched for answers, all I can find is alot of guessing.

I have a 2006 Ram 3500 SRW 4x4 5.9, I have had the 48RE Built by 2 shops in the last year, so I'm out a few grand there. This third time I built it myself, it has all billit servos, reds in the main case, high energy in the OD, gorend valve body, 3.8 apply lever, billit input shaft, mag hytec pan, GM conversion solenoid, DPC triple disc, low stall, 6 pinion planetary. Every few hundred miles I'm getting P1740. Truck shifts fine up and down. what is the fix? Will this damage it to drive if it's shifting fine?

I have EFI Live, AFE Stage 2, Pusher intake, 5" Diamond eye turbo back, Air Dog 2 100 GPH, 2" level, 285/70R17 BFG TA KO, steering box stabilizer, suspension max away bar end links, rancho 7100 shocks.
 
1740 = Common issue with a few.

My old 07 did it some... Never hurt anything...

Can't remember the fix for it though.

I'd call goerend. I believe he puts a resistor in some of his builds on an as needed basis.
It may be for a different problem but I believe it was this problem.

Also that's the torque converter code.
Did you add a lock up switch. With resistor?

Just a thought.
Confirm it's actually locking the TC when it should.
 
its from the big rpm drop going into lockup with a triple disk,had it for years cleared it out and one day it stopped coming back.
