Good Afternoon,
I have a 1996 F150 4x4 with about 77,000 miles. When driving at about 40-50 MPH it would shudder (this has been going on for quite some time). Once over that speed it would be fine. I seldom drive the truck but the last two days it threw two codes at me: P1120 (Throttle Ps Sens A Out of Range Low (Rath low)) and P1741 (Tourque Converter Clutch Solenoid Ctrl Error). So my questions are:
1. are they related?
2. Would they cause the shudder?
3. Anyone know where the TCC solenoid is located on a 1996?
I've researched these forms quite a bit over the years and I always that it was the tourque converter itself. But now that I have the codes maybe its the solenoid. Is that easy to replace? Any feedback would be very helpful.
By the way, the transmission fluid was recently flushed earlier this summer.

 

Well, if your TCC is malfunctioning it sure will shudder
Better work on that 1120 code and the 1741 before thinking about replacing the converter
Some of those big TCs did shudder slightly in your trucks era
I would not replace it now, wait till it needs a new trans
Fixing the codes might help or solve the problem

 

Thanks ManicMechanic! That's my plan. I'll work on the codes and report back. I have no desire to replace the converter, nor the ability! So hopefully fixing the codes will do the trick.
