2010年7月13日 · Code Description: P1740 - TCC / OD Solenoid Performance Functional Operation; In order to ensure proper operation of the torque converter clutch and the overdrive clutch, the PCM monitors the engine RPM and the output shaft speed while applying the TCC and/or OD solenoids.

2014年7月4日 · In plain simple terms this code P1740 is directly related to Torque Converter itself, which is being control by couple solenoids inside the transmission for TC to go into lock. I happen to know about this as I have an 2005 year 48RE series trans. It is throwing the P1740.. 140K miles.. second owner..

2016年9月30日 · P1740 is thrown when the pcm doesn't detect tq converter lockup. If you haven't noticed any difference in drivability, what the problem LIKELY is is your lockup is weak. I myself have been rolling around with the same code for 5 years now and my truck gets beat to hell. Lockup is virtually undetectable in my truck but it does do it.

2011年8月15日 · P1740 fix Hey guys, so I may have gotten lucky with mine, a few times now. So this is the 2nd time this has happened to me: When I am driving down the period after an extended period of time my truck will pop a 1740 and drop out of OD on me. Had a tranny expert friend take a look the first time (2009) and it turned out it was a "speed sensor."

2015年4月7日 · I recently had the 48re in my 06 megacab rebuilt with a shift kit, billet servos, and some other upgraded parts, including a low stall, single disc torgue converter. The truck right away had a p1740 code while still at the shop. It was cleared at the shop using a scan tool, driven for a week, and popped back up while my wife was driving it one day.

2017年2月9日 · The other day engine light went on. Went to 3 different shops (Advanced, O'Reileys and Auto Zone) and the reader showed code P1740, TCC or OD Solenoid/Automatic Transmission Control Solenoid. Does anyone have a schematic where this is so I can change it? Is this correct diagnosis? It is confusing reading the responses on this code.

2009年1月19日 · About a week ago, the check engine light came on and I took it into Autozone to get checked out. It was the code P1740 which is TCC or overdrive solenoid. I need to get this fix asap cuz it is my daily driver. If anyone has pointer for me in …
