OD light flashing

[brettly86]

4/1/14. 2000 Eddie EX. 5.0v8 awd. Hey guys. So I was driving to work the other day and I noticed that my tranny was trying to grab OD then it stopped trying and my OD light started flashing. The whole day my tranny would not go into OD. I've been driving it the last couple days with no problem now but when I back out or turn into a parking spot it seems like my 4 wheel drive is binding. Any hints to what might be going on would sure be appreciated. Thanks.

When the OD light flashes, the computer stores a code as to what is wrong, you need to get the code read.

Scanned the code and it's p0741- torque converter clutch stuck off.

There are many things that can cause a P0741 code, it might be the TC solenoid, gasket failure or seals causing to much internal leakage, valve body, wiring or the torque converter.
Sorry there is no one answer for this problem.

What if you don't receive a code for the problem can it be the button on gear shift

One more time then! You all can check whether it is OD gear or Torque converter Clutch which is failing to engage. Get the vehicle up to cruising speed, watch the tachometer as you do it. Tach shows drop in rpms, now in 2nd. gear. Again, 3rd,. then 4th, then 5th (OD), then yet another drop, a 5th. drop. If you fail to get that one, the TCC has not engaged. Soon the O/D OFF light will b egin flashing.

You can always test whether the TCC has engaged by LIGHTLY applying more gas pedal. If the clutch has engaged, the tach will not jump up in rpms instantly. The TCC is the LAST engagement upon reaching cruising speed. Releasing the gas pedal at cruise will show a drop in rpm on the tach as the TCC disengages; it disengages EVERY TIME you get off the gas. Bring the rpms back up, you will see the tach drop back down, as the TCC engages. imp
