Guys - you may have seen, I got a new '87 V10 - great truck. It's been sitting since 2002 with minimal starts. - Runs great (other than popping the heater core).
After driving it a day, it started drop rpm's at a stop or even a slow roll (like parking in a parking lot) - it happened more when turning - I serviced the t-case and it helped. it was still dropping at stops and slow idle moving. -
So, I put a can of seafoam trans tune in the tranny - after about 40 miles - beautiful it was!! It would come to stop and or slow idling thru a parking lot purring like a kitten. It would slow roll - beautiful.
Well, it was short lived - 2- 3 days --- and it's back at it. Its as if the converter is not unlocking as it should- when I feel it happening, I can put her up on Neutral and it idied- purrs perfect) -
