Idk whats going on

Here's some rudimentary info re. OBDII. First thing is to check pin 16 for battery voltage. Looking at front of dash connector, top row is pins 1 - 8 from left to right. Bottom row is pins 9 - 16 from left to right. Pin 16 is Battery+. No power is usually blown fuse. Pin 5 is Signal...

700r4 torque converter lock up question.

I've got a 700-R4 in my 68 C10. I use a toggle switch on the dash to control the ground for the TCC solenoid. Completing the ground will lock up the torque converter clutch. Breaking the ground will disengage the TCC. To hook up, you only need two of the four pins on the trans connector...

Highly Erratic Speedometer.

I never saw any problems with any of the gages (or tach) other than the erratic speedo.

Highly Erratic Speedometer.

Yep. The new (to me) cluster from LKQ fixed my erratic speedo problem. Still haven't looked into swapping the odometer yet. I also plan to take a look at the old circuit board to see if I can spot any fried resistors or other obvious problems, but I'd guess it's mostly surface-mount stuff so...

Highly Erratic Speedometer.

I have not seen this problem referenced before, so maybe I'm the only one who has experienced it. My '94 GMC C1500 350/4L60E began having speedometer problems maybe a year ago. Started with the speedo needle bouncing around a little, then progressed to bouncing a lot. Would occasionally read...
