I HAVE A 1994 CHEVY G10 WITH A 4.3 VORTEC V6 AND AN ELECTRONICALLY
CONTROLLED 4SPD TRANS WITH OVERDRIVE. IT HAS AN INTERMITTENT SHIFTING
PROBLEM. SOMTIMES IT WILL SHIFT FINE AND OTHER TIMES IT DROPS INTO WHAT I
BELIEVE IS 2ND GEAR AND WILL NOT SHIFT. I HAVE REPLACED THE SPEED SENSOR
THAT IS LOCATED ON THE DRIVERS SIDE REAR OF THE TRANSMISSION. I WAS TOLD
THIS IS THE ONE FOR THE SPEEDO. I WOULD GREATLY APPRECIATE ANY HELP.
THANKS

1. Turn off your caps lock key. All caps is SHOUTING and we don't like
it.

2. What are the fault codes from the PCM? You did get codes *before*
wasting money on unneeded parts, right?
