Due to some tranny shudder I decided to check the TPS voltage and found it at 0.4 V. Attempted the fix by widening the slots and couldn't get it above 0.9 V. After I was worried about nothing being left of the slots I decided to check the throttle linkage length (Recall #B15 was done before I bought the truck). It was 1/8&quot; too long. Easy adjustment with a 10 mm wrench, set right at 5&quot; (Recall B15, Throttle Linkage). Rechecked the TPS, voltage easily up to 1.2 V. Transmission felt less sloppy and quicker throttle response. Long and short of it. Before TPS changes - check idle, check throttle link then adjust. Hope this may help someone out before the blow out the side of a $200 TPS.<br><br>Paul
